I got a job two months ago working for a subsidiary of Motorola. We install and maintain radios across a Midwestern state for municipalities, counties, and some corporations. I've been to some tower sites, dispatch centers, etc. Mostly I've been installing mobiles in police vehicles and shit like that.

What cool stuff should I look into related to the job? I have a technician license and a couple of baofengs but they are pretty much unused. I know more about programming the radios and installing them than I do about operating them.

Are log periodics the best options for multi-band antennas? Gain similar to a 3-4 element monoband yagi, on every band, with <1.3 swr and no tuner needed. What's not to love?

I bought a portable vertical antenna bc I want to get into POTA. Set it up this morning and had the SWR at 1.07 on 40m. A light drizzle moved in and SWR shot up to well over 5:1. SWR changes are normal when the elements of an antenna are wet, but I've never seen a swing with such a drastic swing before.

>>2795460
So what, you're playing with a tech license and some walkie talkies? They're basically a jailbroken bubble pack frs radio that happens to transceive out of band. There's nothing job related there. Just focus on installing radios I guess.

>>2795476
If that's in your price range, go for it.

>>2795476
>What's not to love?
not a resonant antenna, weight, wind load
certainly pricey
depends on what you want to cover ?
20-17-15-12 3-4 elements yagi seems reasonable compared to that, you can complete with a 10-6m 5-6 elements ?
yagis for 40 are huge and you need to put them really high, but if you can.. Or get those yagis with variable element length, can't remember the name, they are fucking expensive of course.

>>2795478
Check the feedline, connections and antenna for water ingress. What are you using for a ground plane?

>>2795478
you might have a short somewhere because of the rain, can you try to increase the insulation between the radiative element and the rest ? Maybe put some tape, epoxy to make it weather proof ?

>>2795484
8 16.5ft radial wires

>>2795482
>not a resonant antenna
Nta but log periodics are indeed resonant antennas. The elements used are resonant for their intended bands and optimized for amateur frequencies. Take one far enough out of band and you'll see swrs start to spike.

>>2795482
>Or get those yagis with variable element length, can't remember the name
They're just multi band yagis or beams. Unless you mean a steppir that has motor control to move the elements. They're extremely expensive and require steppir software to use. They're also not self-serviceable.

>>2795492
>steppir
thank you, it was that

>>2795476
If you have the tower that will support the weight and heft of the antenna, I say go for it. There are "better" options in the sense that there's higher gain options. A 4 band cubcal quad with full length elements will have significantly more gain, for example. It's also a 3d antenna and has a significantly bigger footprint and windload though. A smaller, lighter, cheaper option is a hexbeam, but they have much less gain and f/b rejection. Keep in mind, a log driven antenna like your pic needs height. It's like a big dog in an apartment. It needs a big yard to roam, so plan on 45-60ft of height to get the most out of that antenna.

>>2795495
>4 band cubcal quad
Sorry, 5 band 4 element (per band).

Is there any point to an Icom R8600 if I also want a 7300 and 9700?

>>2795604
A very expensive way to work spilts when contesting.

>>2795614
I guess I should have explained a little more, I'd like to receive as many bands as I can, not just the amatuer services. I also want something that's a little more oriented toward receiving than my SDS200

Your response is unnecessarily abrasive. The suggestions I was looking for did not have to relate to the radios I purchased.

continue to ignore a literally who

>>2795717
He keeps saying ground the antenna. Most antennas should NOT be grounded, unless utilizing ground radials. Balanced antennas aren't grounded nor are elevated verticals. The masts should be to prevent static. Your radio is grounded, but don't rely exclusively on your outlet for ground.

>>2795689
>I'm just asking if there is anything within the hobby that might come up on my job that I can look into or research
Idk, you're the Motorola installation tech and you're also a licensed ham radio operator. Did they not cover this in your test? You don't know what the hobby is about? Anything radio, there's your answer.

>>2795668
No. And as far as a counterpoise, the coax shielding acts as the counterpoise.

>>2795394
I have a truck with tie down brackets I'm not using.
I like the clean look of these brackets - would it be crazy to get 2 - one for VHF and another for HF? seems like a logical design, but I can only find one manufacturer.

>>2795818
Easier and better to use your whole roof as a counterpoise.

>>2795825
we're back to sticking a 4 foot hf antenna on the roof of a truck cab?
It's an aluminum body and I don't want to do anything permanent.

>>2795826
Ah, yeah that's why I mag mount. Parking garages just knock them over safely because of the mag mount, but it's strong enough for 110mph winds which is as fast as I'll ever drive my truck. You really do want a counterpoise for a vertical and the big metal body works wonders. Usually.

>>2795717
what is blud yappin about
only in ohio...

>>2795733
me personally, i wire a lightning arrestor inline with the coax directly to my cock and balls, so if lightning hits the antenna my ejaculate prevents any arc transmission

i call it a lightning rod

>>2795476
It works for the Vatican.

>>2795476

>>2795916
That is impressive.

Up until the 2000's a lot of embassies around the world sported log periodics on their rooftops.

>>2795476
I've talked to a couple of HF LPDA owners over the years and they bought one so that they only have one antenna on the mast. Sort of a "buy one, now it's done" thing. The trade-off is mild gain when compared to monoband yagis with the same number of elements.

Personally, I like the looks of them.

>>2795717

>>2795944
>The trade-off is mild gain when compared to monoband yagis with the same number of elements.
Logs also have some of the most extreme examples of F/B rejection. He posted an optibeam, so I'll run a comparison with a similarly sized one.

OB11-5 / 45kg:
Bands 20 / 17 / 15 / 12 / 10
Gain (dBd) * 5,3 / 5,5 / 5,6 / 5,6 / 6,7
Gain (dBi) ** 12,7 / 13,0 / 13,2 / 13,4 / 14,5
F/B (dB) 22 / 22 / 20 / 19 / 19

----

OBDYA12-5 (image he posted) / 55kg
Bands 20 / 17 / 15 / 12 / 10
Gain (dBd) * 5,08 / 5,05 / 5,25 / 5,25 / 5,41
Gain (dBi) ** 12,1 / 12,5 / 12,6 / 12,7 / 12,9
F/B (dB) 26 / 27 / 35 / 27 / 29

So less gain but more F/B.

That's with a band optimized log. With a true log periodic like the OBLY16-5 we see this. / 80kg
Bands 20 / 17 / 15 / 12 / 10
Gain (dBd) * 5,4 / 5,4 / 5,4 / 5,4 / 5,7
Gain (dBi) ** 12,8 / 13,0 / 13,1 / 13,2 / 13,5
F/B (dB) 35 / 35 / 38 / 33 / 35

So, logs for good gain and amazing F/B, "mixed" yagis for better gain, less weight, and less F/B.

>>2795700
I agree, we could use something new.
Should I bust the balls of those doing POTA or bust the balls of those busting the balls of people doing POTA?

>>2795953
I'd argue logs look so much cleaner than this mess, so you have to decide if F/B or gain matters more. Especially since logs weigh more. An OB16-5 is even better and has less weight than the log posted above, as it's 75kg.
Bands 20 / 17 / 15 / 12 / 10
Gain (dBd) * 7,1 / 7,2 / 7,3 / 7,0 / 7,7
Gain (dBi) ** 14,5 / 14,7 / 14,9 / 14,8 / 15,5
F/B (dB) 18 / 20 / 22 / 24 / 20

In this case I'd almost prefer this yagi. Assuming price isn't of issue.

What's up with Japan flooding ebay with tons of cheap IC-706s?

>>2795956
>price isn't of issue
What would you recommend for under $800? Coax, antenna, and tower assembly included.

>>2795996
Site prep for a tower is going to easily be over $1k.
>under $800 Coax, antenna, and tower assembly included.

>>2795996
Don't bother with a beam at all. Sure, you can make a hexbeam relatively simply with trial and error for under $400, and it'll be the same as any commercial variation. That said, ~50ft of RG8X, a rotor, and a homebrew mast would start pushing you well over $800. I'd suggest a multi band vertical or making/buying a fan dipole. A good 3-6 band fan dipole will be a sufficient antenna for almost anyone. You can easily make 3 30ft pushup masts, then put one fan dipole N/S and the other E/W, using the same center mast for both ends. Don't run them in series, just use 2 feedlines to the radio or a switch. That avoids the need for a rotor, and you can horizontally polarize both fan dipoles.

This guy did the same thing using a cage fan and traditional fan dipole. The beautiful thing is that the elements shouldn't interact much, so you can actually go 160-6m with the same dipole and feedline. In theory.

>>2796002
You don't need site prep. You dig a hole 5x5ft, place your tower in, level the tower, and fill with bags of cement and a garden hose while tying the tower down or attaching it to a house, wall, etc. Make sure it's level before leaving it. I used to work for a tower install company and this is literally what we'd do, if you have the blueprint for your home or have an available copy you should know where water lines, septic/sewage, gas, etc run. If not, a survey only costs an additional $50 for us to call 811 and mark utiliy lines (a free service in the state). We actually used quikrete because most of the time we couldn't fit a cement truck on site. We did have a pickup with a 50 gallon water tank, however, as well as hundreds of feet of hose hookups.

>>2796011
not him, but that's awesome.
I'd love to get a few acres and setup an antenna farm.
I was hoping with a ghetto harbor freight concrete mixer I could pull it off myself.
just gotta get land and maybe used towers.

>>2796002
Another asshole who has no idea what he's talking about, cute.

Is there anything wrong with getting one of these mounts and sticking a 10ft pole in it on the roof and running a bolt through? Will it hold a 2 element 10m yagi?

>>2795949
It's not that.
Him and this guy seem to think that having a ground wire going from the chasis of your transceiver to a ground rod outside your shack is a violation of the NEC.

Even if that rod is bonded to the house's main ground rod at the meter.

>>2796011
>Just dig a hole, throw the tower in the bottom with some quickcrete and fill it with water
>Don't worry about settling, just tie it to your house
>Also fuck lightning/ground protection it's already in the ground right?
Concrete costs money
Digging costs money
Clearing land costs money
Water costs money
Guy lines + anchor points (more holes and concrete) cost money
Mounting plates and hardware cost money
The permit (or fine you are assessed later because of your freedoms don't need permissions) cost money
After the base is done,do you plan on waving a magic wand to assemble the tower and put the antenna up? I mean you're going for a beam/yagi, so you can just climb the tower with one hand and haul it up with the other. I guess you can use the magic wand to materialize the rotator, bearings, power cables, and the free coax too. I'm sure you'll be doing this over one weekend with the help of someone you paid with 2 cases of piss water.

>>2796206
Why would you call yourself cute, big boy?

>>2796337
>Concrete costs money
$6/90lb bag, probably the least expensive construction material in the world
>digging costs money
A 5x5 hole is shovel work. Ask me how I know.
>clearing land
This really depends on the land. Open desert/dirt? No. Lots of trees/shrubs? Maybe. It's too major of a variable.
>water costs money
Least expensive utility. Filling a 5x5 hole is less than running a pool for a day or two.
>guy wires/anchor points
Most of what we did was free standing towers under 50ft for residential. Beyond 50ft yes you need guy wires. For some 30-40ft setups like a rohn 45 or heavier gauge tower, I suggest guy wires. Costs vary, but another 400lbs of concrete per anchor is under $30, the anchors themselves are like $10 each, and then the guy wires themselves depend on what you decide to use. 660ft of non-resonant Kevlar or Nylon braid with 6,000lb breaking strength was like $150 at the time. More than enough for what you'd need. Way more.
>Mounting plates and hardware cost money
We suggest digging the tower in as opposed to mounting to a mounting plate UNLESS you plan on a tilt over. As for rotors and antenna mounting hardware not included with the antenna for some reason, yes they cost money. In my experience antenna/tower mast mounting hardware can be purchased for $15 at your local hardware store. A rotor will always cost money, which is why I suggested an option to avoid it entirely.
>permit
Our city does not permit amateur radio tower installations. Ymmv. I suggest looking into what costs are, you may not need one under a certain height. You are still required to follow FCC guidelines on tower and antenna installation, and local code for grounding.
>last part about assembly
With a dig-in installation you should be able to climb the tower. Otherwise you're looking at a crane or bucket rental. These usually cost ~$100/day for a wheeled boom lift or bucket. A crane varies from $180-300.

>>2796337
Continued, yes I have climbed towers during assembly. You may or may not need a bucket or boom lift after the first 10ft. It depends on the weight and size of the tower sections. Rohn 25g weighs 30lbs per 10ft, so 2 people with gear can and will climb the tower with individual sections to install them up to 30ft. Beyond that, you need a bucket or crane. I'd often climb the tower while the crane operator gets the section close enough to guide it in and bolt it down, even at 100ft. Someone needs to guide that fucker in and start running bolts. At 30 or 40ft, just climb it. I've free climbed them doing it plenty of times too.

As for labor costs, for some hams I'd do it for free, since they had helped me with my installation in the past. For company work most of our money was made on commercial jobs. On residential amateur radio jobs we'd only get like $150/day each for 3 people. My point though is that you don't need a professional crew to do it, I've erected a few 30ft towers and dozens of masts solo.

>>2795700
>I posted it again for the hundredth time
we will never stop as long as this thread is continued.

>>2796336
At first I thought he was trolling and would make the distinction between bonding and grounding, but he was dead serious.
I've spent some time exploring antenna grounding and adding grounding rods and how many and where I broke was tying grounding rods to grounding rods.
There's no magic added by tying together the grounding rod from my house to the grounding rod to my shed. And to my antenna - because by that logic my house's grounding rod must be grounding to all my neighbors' otherwise the entire infrastructure will be destroyed.

Are there any mobile radios that are particularly/slightly more weather and moisture resistant than others for outdoor base camp use

>>2796415

>>2796430
dude go be a faggot somewhere else if you have nothing to offer

>>2796415
I'll give you some advice. When you take a motorola in for service as a construction crewman, that sucker is abused and CAKED in dust, dirt, concrete dust, and is exposed to moisture all the time. Unscrew the thing, take it outside and hit it with the garden hose. Then wipe it down and hit it with the hose again. Take it inside and put it on a glass or ceramic baking pan and throw it in the oven at ~200 degrees for a few hours. As long as the radio isn't on and the battery is disconnected, there's nothing to melt or get damaged at 200 degrees. In fact, the plastic they use for the mobo and shell is baked significantly hotter when cured to begin with. Knowing this, I no longer worry about super hardcore outdoor radios. The same applies to any HT. That said, an 8-10w HT (they do make them) with a massive battery will serve you just as well as most mobiles when connected to an external antenna. Worst case scenario just keep the thing in a ziplock bag.

>>2796434
Get a tait. Actually I do have something to offer. See this anons comment:
>>2796436
A twenty five year old motorola would be a good investment too. When they say they don't make em' like they used to. Motorola fights in to that. They used to be great before they outsourced all the engineers to india.
Instead of water I would recommend isopropyl alcohol from the pharmacy. More controlled.

>>2796322
>Will it hold a 2 element 10m yagi?
Mine holds a 25ft high 6-20m hexbeam with a medium duty rotor on top. If you have any doubts just throw another cement block on. Make sure the roof is supported too.

I considered juggling 2 radios and splurging on a new VHF/UHF radio, but at that point I may as well spend a few hundred more and get one that does both. Especially when IC-706s are in the $400 range
>>2796636

I have a IC-7300. The IC-7000 seems almost like a prior generation of that. Color screen, same button layout, etc, with the bonus of a removable screen.
For whatever reason, in-between those two models is the 7100 which looks like a big step back. Black and white, an odd, angled screen, and the buttons look as if it were made in China. To their credit they introduced the touch screen. I suppose I mean gimmickly in that I can see this is how it went at the ICOM business meeting

Hi Randy!

>>2796738
right now just a discone, which is surprisingly good at picking up 40m, getting ready to setup a wire transmit antenna, I would setup a beverage but my property is long and thin so it would probably be too close to the transmit antenna

>>2796842
>discone
It works well if outdoors, but I've had discones before, a true blur resonant wire high up in the air will make it look and sound like shit. That said, they're neat antennas and work fine for shortwave stations.

What kind of transmitting antenna do you use? A beverage shouldn't interact if properly staggered.

>>2796854
it's gonna be a long EFHW
I live on an acre but it's long behind the house so the wire is gonna be strung from a pole right behind the house over to a tree, wire will be running towards the north. If I did a beverage also going north I feel like it would be too close to it but idk. Could always do an east west beverage just to see what I can hear.

>>2796892
>I feel like it would be too close to it but idk
If it's >20ft away and 5 feet higher or lower, it shouldn't have any interaction at all. I'd also argue for a dipole of some sort, even a fan dipole.

If you aren't a practised portable operator, do some SOTA or POTA first. Work out what you need to take and what you don't. Handling high QSO rates per hour is a learned skill too.

You can take a laptop and just leave it working FT8 while you relax on the beach for some extra lolz.

I'm converting my batteries, power supplies and radios to Anderson PowerPoles this weekend. I need to make a few pigtails. What is the preferred method, using separate wires or zip-wire?

>>2797402
>using separate wires or zip-wire?
whatever you can find, both are ok, twin wire will be less messy

>>2797402
I have a leads that are just single wires bonded together in glue lined heat shrink every foot or so. Easy way to make high current leads, bond 3-4 single wires per pole together in parallel, heat shrink them. That way you can use whatever wire you have in the junk box and not spend big on heavy gauge twin line.

>>2796692
>That's why an MSPaint of someone using a vertical random length end-fed to dx is circulating here, they've never tried better antennas.
I just like my simplicity and not having to waste a lot of money to make the antenna jews more money when I make DX contacts just fine with my wire up a tree.

>>2797438
You know you could make a resonant antenna without paying antenna jews? Oh, of course not you're not a real ham. You think a contact to Canada or Cuba is a dx contact.

>>2797486
You know you can stop seething over someone not doing the things you want them to do? Oh, of course, you have autism. You think anyone who doesn't do what you do is not a real ham.

Tried to make this circuit in falstad but failed. My brain doesn't really comprehend what the two wires on the bottom go.
Left side is just straight from wikipedia.

>>2797487
*yawn*
Post antenna.

>>2797491
*yawn*
No thanks.

anyone know what program they use to do this?
It's some group that likes to mess with the russian buzzer stations

>>2797512
I have a program that'll do this, but they'd have to run some serious power for it to be this pronounced. I use Easypal. That said, you'd need great conditions and a very strong signal to do something like this, to this level of clarity, so they may be using commercial broadcasting equipment.

>>2797527
the youtube channel I'm watching them on also adjusts his waterfall to make them look as good as possible with the prerecorded audio he's working with
but it' some russian shitposter messing with the russian mil
originally they didn't even really respond but now if they start playing music or rolling sstv on the freq the gov station just goes key down on the noise

>>2797529
Ah yeah, for recorded audio it's definitely easier to do. If you were to log into a US based SDR I could produce this on the waterfall, but it'd be harder to make out for sure.

>>2797205
I imagine they've nerfed it to avoid liability suits. People have used it to do homework, write reviews, and some idiot even used it in legal proceedings and got his ass handed to him.

>>2797554
They're nerfing it constantly, but still aiming to improve it so more people use it. It's very retarded.

Still I could ask it in Swedish how many coils I needed in my secondary loop in a transformer to get the right voltage and it did it correctly and showed work.

>>2797562
Here I ask about the dipole and asking it to help you make a high power dummy load for a specific wattage will give more obviously terrible answers.

How many folks do this to their 12vdc input? Effective?

>>2797566
It told me to use 2 pieces of 10.36meter. Unsure if this is good for 7Mhz since I literally know nothing.

It's all magic number math to sound smart anyway

>>2797571
I mean, it's right to tell you to go longer than you'd expect so you can tune down.

>>2797571
Are you sure that it said each side is 10.36meters? (correct)
In english it will always say each side of the dipole is 20meters or a similar logical fault (incorrect).

>>2797573
In the image under "Material" "Two lengths of conductor (copper wire, coax or similar) with an approximate length of 10.36 meter each.

I wonder if there is an overabundance of Swedish radio material online compared to general English stuff vs English radio stuff

>>2797570
Don't think that was done correctly.

>>2797643
Maybe so, but Palomar is selling them for $35.

done a bunch of studying and my two practice tests so far for general are good. 83% the first time and 91% the second time a few hours later.
Gotta really pound it in there since I'm gonna be taking the test on a Saturday after being up 16 hours. Needs to be second nature.

>>2797814
Be sure to take regular breaks. You can tire yourself out to the point where you get worse.

>>2797820
it's Saturday the 18th so I have some time
Just sucks I work weekend nightshift
So I'll go to work Friday night at 5pm, work 12, get off at 5am Saturday then stay up till the 9am test. Then go back to work that night.

>>2797824
Fellow midnight shift bro! Hope you do well on the test!

>>2797826
Thanks
been doing it 8 years now
on the plus side on my days off I'm up at the good propagation times for 40m, already been listening to it at night

was expecting a few more winds in this "2kw" 350w digital transformer for an EFHW 75-10m
lots of ferrite in there though

>>2797848
triple stacked

>>2797571
Don't trust that bullshit. ChatGPT is just a poor, re-written google search that hasn't been updated since January 2022.

>>2797827
I did that for the longest time on 80m and talking to some of the boomers in the region.

>>2797849
The primary winding (the two twisted wire) should be at one end of the secondary winding, not in the middle. Who made it?

Also note use of typical cheap shit cap in a high wattage transformer.

>>2797890
myantennas.com
Supposedly designed by a former cushcraft engineer
https://myantennas.com/wp/about-me/
guess we'll see how it performs once I have it strung up
here's a shot of the cap
says 121J 3kv TDK

>>2797890
It doesn't matter where on the secondary the primary winding sits. People who make ununs usually wind the primary over the earthy end of the secondary, but it's not at all essential. The actual winding itself looks OK for the standard of something made commercially. I am glad MFJ have gone bust and they will not be inflicting their shit ununs on the world any more.

>>2797895
The cap is OK. The selection for a cap in that application is not just voltage, it is loss at the higher end of the spectrum. So 3kV is fine but it will depend on the materials in the capacitor how good it is at the top end.

>>2797916
The primary is at the ground side electrically but the secondary is split. Dumber than a box of rocks and should be rewoumd Those cheap TDK caps are shit ESR performers at HF

>>2798032
French fag here, saw some very faint aurora, that was nice, i guess radio conditions will be strange but maybe good for some bands ?

I was promised solar activity. WHERE IS IT?!
Everyone on Infowars today was going full blown Y2K over a few sunspots
>The Carrington Event melted all the electrical wires!
>Sun spots make people go crazy!
>If it doesn't happen ... the govt will use it as a false flag to do something and blame the sun!

>>2798076
I also heard lu1wfu on 6m today. It's coming, give it another hour or two.

>>2798121
I've been watching on ft8. There was a small window where I saw some South America and someone made a contact from Central America to Australia.
Otherwise it's all this very wideband, undecodable noise.

>>2798122
What antenna are you using? 6m requires a pretty substantial beam. A thousand people were getting into SA.

>>2798032
Now classified as a G5!

If I try to use my SDR or shortwave radio during this, is there a chance I could damage it?

I understand a bit about how solar storms affect HF transmissions, but this is the most serious storm that's happened since I've gotten into radio.

Is there anything you recommend doing to take advantage of this event? Anything fun I might regret not doing later?

>>2798139
tfw left my SDR hooked up when I left the house for the night

>>2798139
>>2798146
A power surge might damage electronics. That's about it.

>>2798127
I'm the moxon goof. Been working 6 meters pretty hard the past week or two.
Either it's the conditions or I made a big goof I haven't found

>>2798156
switched antennas and same woes

>>2797490
It's a circuit. Think of U1 as a voltage source with the positive on top and the negative on the bottom, and U2 as a load modeled by a resistor.
Current flows from U1_top to the top-middle intersection to U2_top to U2_bottom back to U1_bottom. But there's also the flow from U1_top to top-middle intersection to bottom-middle intersection back to U1_bottom.

Would putting ferrite chokes on the coax cable running from the MLA 30+ to the power supply improve or degrade signal quality?

Should I only put ferrite on stuff like power supplies or thinks drawing a current?

>>2798139
Came here to ask the same question.
I've got an RTL-SDR and was thinking about plugging it in to monitor activity locally (I'm trans btw, not sure if that's relevant or not).
I'm assuming the CMEs would shit out noise on all spectrums, so it wouldn't really matter what frequency I tuned into?
Also, would like to start discussion about EMF-protecting radio equipment. Would lining a box with alfoil actually work?

>>2798174
>from the MLA 30+ to the power supply
From the antenna to the radio you mean? Or the radio to the power supply? You don't have your antenna connected straight to a power supply. Either way, ferrite beads don't do much on receive even in noisy environments. Better coax usually does what you're looking for. You could ground the radio and antenna which should bring noise down for low bands.

>>2798174
>>2798219
Sorry, ground the radio and power supply*. Do NOT ground the antenna.

>>2798139
>If I try to use my SDR or shortwave radio during this, is there a chance I could damage it?
Not at all.

>Is there anything you recommend doing to take advantage of this event? Anything fun I might regret not doing later?
You'll hear a lot of 'Dawn Chorus' emissions on ELF. Check out the VLF region for enhanced propagation.

Point a 6m yagi at the aurora and listen to the watery sounding CW signals. It gets weird. SSB might be too distorted to understand but worth a try. Swing the beam at different parts of the auroral curtain, some weird reflections can be had. One time with the beam pointed true north, we could hear stations to the south of us. Then minutes later we're getting sigs from Denmark for just a minute or so (over the pole). Then we're hearing JA's for a few brief moments.

Beautiful. I wish I didn't sleep all night

HF is looking pretty barren
All I can see is FT8 & CW down on 40m
little hints of LSB on the net frequencies but nothing intelligible

>>2798320
Yea,I'm not even seeing anything in the broadcast bands.Pretty crazy,I've never seen conditions this bad.

>>2798320

>>2798373
POTA in Florida. Trying to fight through the noise, but he gave up.

I didn't hear anything unusual on MW last night but SW seemed almost completely dead

I will try again today and tonight. Also it was cloudy where I was, so the towns adjacent to me enjoyed the Aurora while I didn't, which I'm extremely salty about.

Anyone have a speaker recommendation for a mobile setup?
Never thought it was applicable, but I put the base in a lockbox in the back and that's where the speaker is. At max volume it sounds like a crying baby with a pillow over their face

>>2798535
I used a commercial Motorola mobile mount speaker for years. But I did see one guy who used one of those little FM transmitters used to pipe music from an mp3 source into their car stereo system.

>>2796337
WTF. A lot of people with land and a tractor probably have most of the supplies to do this type of shit by themselves

So what's the deal with the spanish guys on 7.130? (and the rest of the AE part of the 40m band)
Cause I can hear them all day everyday with even the shittiest antennas
I know some people talk about the fishermen on 40m but I am absolutely no where near the ocean

I'm fascinated by radio, it's crazy to me that I can have an antenna up and hear all kinds being transmitted. What do you people do usually? Talk to random people? Or just curious about what's being transmitted at the moment?
Is there a lot of "crackers" in this hobby? I mean people who jailbreak radios and try to listen to LE frequencies and shit like that I'd enjoy that desu i know I sound like a fed now.

Me and my buddy have a baofeng walkie talkie that we take to the desert for camping but I want to do more than that, just want to learn more about the hobby before I spend too much.

>>2799142
most radios don't have limits on what they will receive other than technical ones
SDRs can receive huge bandwidths
You can try to listen to LE but they generally use encrypted trunk systems these days
people have been listening to police frequencies as long as police have had radios
Now transmittitting out of legal bands is a whole nother thing, and has always been fairly easy to do. Boomers just needed different crystals or a VFO that went to those frequenices. Most modern ham radios to this day usually just require a simple hardware mod to generally remove a resistor to allow them to transmit outside of the USA amateur bands.
This is generally referred to in the US as WARC modding a radio. Also people that modded HF radios for 11m(CB), people using illegally high power amps.

>>2799145
>transmitting out of legal bands is a whole nother thing,
yeah I'm sure I'll get caught in a second if I did that

forgot about encryption, that takes a lot of the fun out of it man

I am in Saudi Arabia and every radio device has to be registered on a database, is there like call sign based on the serial number or something?
actually how is the surveillance on radio in most countries? It might be fun to make a vulgar, not PC radio program out of my car I'm sure the government won't bother listening

>>2799142
Most of the info you are asking for is in the OP text.

>>2799151
>actually how is the surveillance on radio in most countries?
It is monitored 24/7, and also by satellites - again the FAQ gives you details.
>It might be fun to make a vulgar, not PC radio program out of my car I'm sure the government won't bother listening
The Wullenwebers triangulated any HF emitter in a fraction of a second. Today, 40 years later, the tech is even better, faster and more precise.

>>2799120
I wish I was born 200 years ago. This timeline is so miserable.

I was wondering if anyone else is like this:

I have my tech license and have had it over a year. Programmed old police VHF radios, chimed into local nets, made contacts on 10m, and other activities to keep the knowledge flowing.

I am studying and will likely pass my General this week before Hamvention, but realize that I still have a bit of trouble fully understanding some of the concepts on even the Tech. test.

Mainly in how certain antennas work, the electrical theories that go into radios and different setups in general and the math behind them.

Is it normal to be at this stage where I will pass my General but not fully grasp everything, and if so then I assume I will learn it through trial, error and actual use in the field when transmitting.

Thank you in advance.

>>2799239
didn't read; learn how to write

>>2799239
What are you doing? Just memorizing the question pool?

>>2799239
>Mainly in how certain antennas work, the electrical theories that go into radios and different setups in general and the math behind them.
Time to dive head first into Maxwells equations. you will quickly find that many things are not intuitive.

>>2799239
>I still have a bit of trouble fully understanding some of the concepts on even the Tech
Don't worry about it. I was in the same boat and thought it was me. It's not. A lot of the info in the tests is outdated. It's just like college in that you get a diploma and most of what you learn isn't applicable or in use.
It'd be more helpful if you mentioned what you're interested in or why you got into ham or why you're going for the General.
Knowing the test isn't knowing ham radio.

>>2799241
Sorry, just threw up. Haha

>>2799262
Yes and no. I do know a lot of the equations from physics class and also basic electronics projects that I have done. I have Gordon Wests book and have been doing the HamStudy study sessions and tests.
So if I don't understand a concept I look at the explanations or go deeper into the GW book.

>>2799263
While I do know them, I do not know them 100% by heart and will keep a copy on hand and memorize.

>>2799265
>Don't worry about it. I was in the same boat and thought it was me. It's not. A lot of the info in the tests is outdated. It's just like college in that you get a diploma and most of what you learn isn't applicable or in use.
Glad its not just me.
I got into it originally because of going to the Dayton Hamvention as a kid and wanted to actually learn it as an adult. I want to go for General to understand radio concepts better, what works what does not, and be a better teacher for others in the same boat. Even with my limited knowledge, because I have a tech and am somewhat active in radio, a lot of people that I know that homestead ask me about radio stuff and try to ask for advice on where/how/why to get started.

>>2799272
>what works what does not
That sounds like a 'hands on' type learning which I found after I got the tests behind me. Just pass and set your sights to the hands on activities of your choosing.
The electronics and theories are nice, but few people in the hobby are working on their radios anymore - let alone making one from scratch or replacing all the capacitors.
Back to your original point. If you pass and want to build a radio then find a tutorial and get your hands dirty finding what works and what does not

Interesting fan pattern I'm seeing on 6m

>>2799272
>While I do know them, I do not know them 100% by heart and will keep a copy on hand and memorize.
Memorizing is far from sufficient if you wish to understand this:

>>2799286
>If you don't know why the approximate forward threshold voltage of a germanium diode 0.3v, you can never play radio. NEVER!

>>2799286
I build and sell antennas now, with really good reviews, and I just memorized the test for my general. I ended up learning most of the subject matter after getting licensed.

Anyone hook a ham radio to a motorcycle?

>>2799317
>>2799272
This is what I did. I was encouraged to do it by "Elmers" and VEs. When I sat for my technician exam they said go home and memorize the question pool and answers and come back. I got my extra ticket 2 weeks later. That was 16 years ago.

Their logic was to get you on the air now and then learn by doing hands on. I agree with this model.

>>2799322
The closest I've considered is putting a metal plate in my top box, drilling a hole and running the antenna through the top and hooking a hand mic to my jacket or to the box with a reach-back. Then running headphones via Bluetooth and a small adapter into the helmet. It just wasn't good though, I wanted a larger ground plane even for vhf/uhf, and the antenna would be very high. It'd also run off a handheld ultimately anyway, because loading up my only storage compartment with radio shit is kind of stupid.

For HF operations I'm sure it's doable and reasonable to mount a 10m antenna to a big enough bike with radio hardwired to the battery. If you need your bike for commuting and running to the store though it's not really worth it.

>>2799265
I wouldn't say it's outdated but it's definitely a little overboard. Gatekeeping for the sake of gatekeeping. Not that guy but I'm also studying for my general and it's only the more technical antenna questions I tend to fail at.

Anyone here in the UK take part in the 145 Alive event on Saturday?

>>2799239
I'm exactly the same. I got my general earlier this year when I had the tech for years. The ham radio guy in our community just had me memorize the questions and answers before he'd help me learn. He subscribes to the "the license is the license to learn" philosophy. I learn so much better actually doing instead of book learning.

Also, so far, I've barely applied even 5% of the concepts presented in the General.

I can say 40m is far from dead
threw up my EFHW at a very low height just to do some receiving (about 6 ft off the ground) and I'm picking up tons of code and SSB, was listening to 20m during the daylight hours and it was pretty busy too

>>2799424
and the cw portion is nothing compared to right now
wall to wall beeps and boops down there

>>2799424
They just had a 70+ person OMISS net, 40m is fine.

I'm getting tired of this meshtastic shit that keeps going around on youtube as if it's the miracle cure-all for all comms.

>>2799513
>meshtastic

>>2799513
Keep in mind everyone on /diy/ thinks ham radio starts and stops at their baofang, without ever needing to explore HF. Of course an unlicensed repeater is going to look good to normies.

>>2799151
>actually how is the surveillance on radio in most countries?
lol I experiment between 400 and 500MHz on a daily basis up to 25W and nothing's ever happened. I really dont give a shit about getting busted.

so when does 10m usually open up?

>>2799513

If you're from /k/ the unironic answer to comms is analog security methods and old-school encryption because any kind of strange encoded signal floating around a battlespace will immediately become a priority for intelligence collection

Baofengs are unironically a huge equalizer.

>>2799640
Anything you use will be found anyway. If there's military equipment and boots on the ground, they (being the US military) can track your vhf signal source within, quite literally, second. And no, I don't mean like old FCC fox hunts either. Back when I worked on Nellis someone tried (and severely failed) to jam ATC comms (which are analog) with F16s in the air. Within 2 hours they allegedly had feds at their door. This was all over the base, I'm surprised it didn't make the news, even the pilots talked about it. I guess they didn't want to give anyone else any ideas.

>>2799675
>within, quite literally, seconds*
Plural seconds. Under a minute for sure.

>>2799675
>Back when I worked on Nellis someone tried (and severely failed) to jam ATC comms (which are analog) with F16s in the air
idk about military planes but I heard passanger jets have direction finders to prevent spoofing
but yea, makes sense they will locate you quickly on a band that's used for something as important as ATC
if you wanna stay under the radar you have to use crowded license free bands like ism or pmr and blend in with the crowd

>>2799540
Which is dumb. HF communication is extremely useful.

>>2799640
I'm not from /k/: i just don't really care about encryption. If I need security, I'd rather go through with obfuscation, which we don't need. The only reason why we use DMR is so we privately talk to others on the DMR repeater which is extremely rare anyway. Otherwise, if it's just everyone in the community, we just use the GMRS repeater.

Meshtastic looks more like a meme than anything else. I don't want to have another standalone unit or have it tethered to my cellphone and it's app. I have a DMR radio that does text if I need to text anything outside of cellphone like that cell outage a few months ago.

goddam my local clubs 2m net is depressing
12 check ins and only like 4 of them did any roundtable discussion, started at 7 and ended at 7:30

>>2799812
That's the norm of 2m and 70cm nets.

>>2799814
was so terrible I didn't even bother checking in
wouldn't want to mess up the good old boys and their emergency larp

>>2799817
It doesn't hurt to check in to get a signal report and practice if that is going to be your thing. But yeah, that's how most nets are on repeaters.

>>2799821
eh, I was going to, will see I someone pops up on the repeater later
taking the general in a few days and I'll be on HF

>>2799822
speak of the devil just had my first vhf contact right after I typed that
some guy testing his radio

>>2799822
Nets on hf a very similar, but it's more interesting. An example is you may need to be a relay for another station checking in. You build our skills a lot better on them. Good luck on your general!

>>2799823
Congrats on your first contact! There's plenty more to come.

>>2799825
they actually had a relay during the VHF net
guy was still on simplex and couldn't open the repeater but one of the closer guys to him heard him. He figured it out by the end of the net. I haven't failed a practice test for the general yet so I think I'm gravy. My lowest is 83%
>>2799826
Thanks

its called radio directing finding networking and it can triangulate your transmission automatically within nanoseconds, record the transmission and the location it originated from
RDFN/RDF is an essential part of any government's security in the modern age and all of them have this capability and have had it for many years unless they're still a third world shithole
there are even rdfn satellites and hardware for it mounted to shitty TV repeaters in the sticks
the military hardware for this is a backpack for live finding of hardware in the field, and theres a ton of vendors selling it for cars which works in conjunction with systems deployed on repeaters and cellphone towers
this is public knowledge and generally anyone you see in threads like these mentioning particular frequencies for you to transmit on illegally are employees in the agencies which monitor for jamming or unauthorized transmissions trying to get a bonus to their paycheck for finding you and you've been so kind to use their frequency they've told you to use to do this for them
just use a encrypted radio already you fucking retard its legal and you don't have to register on some public doxxing hub just to talk to your femboy friend across town

>>2799727
>idk about military planes but I heard passanger jets have direction finders to prevent spoofing
Not sure what this means. DF is used to find teh bearing to known radio beacons as a way of navigation, an alternative to using GPS. I have never heard they use DF to locater jammers.
And it would be easier to place the GPS antenna at the top of the aircraft so that emitters on the ground cannot reach the antenna.

although I just IDed one I heard last night
it was Contestia
for some reason it started at the bottom of the 40m band, transmitted, and kept doing that until the end of the band. It avoided any occupied frequencies and the FT8 containment zone.

>>2799965
although it could have been Olivia since listening to the samples I can't tell the difference between them

LOTW has been down all morning

>>2799900
the governt can definitely locate you quicky but I know from experience that they wont waste their time on a random faggots talking on an illegal frequency unless he manages to jam their communications
I know of only one person who got vanned and he was drunk and yelling SOS on marine frequencies

I have never seen a black ham in my life but I'm not in the US. I've been at the big ham fest in Friedrichshafen and it was all middle-aged and elderly white men. Not that I would mind having black men among us.

>Not that I would mind having black men among us.
OH8STN is on youtube. He's decent, but pic related.

>>2800162
What about gay hams? Heard any of those?
You know those rules where they carve out parts of the spectrum for specific for specific things (e.g. no FSK), well they’d probably want to make some of those guidelines like for pitchers and catchers since they’ll be using radios to find each other like fireflies in the night.
There should also be some trans-only bandwidth allocated. They should take AM radio off-line (after which they will crank up cell data plan rates, spotify rates and make everything pay only with ten times the ads, and make you pay a federal emergency alert fee) and assign it all to the trans community.

>>2800162
There are tens of millions of blacks in the US, there are bound to be some, even if they aren't super visible. There are quite a few high school students who get their tech licenses because it's part of a school program, several of those are visible minorities in the photos, even if they don't pursue it as a hobby outside of the classroom they still count

>>2800184
they definitely exist

I didn't do this one but I've done them previously. I hear the one last weekend was a clusterfuck because of tropo

Sup guys. For an uni assignment my group is doing a tracked command post for our army (Spanish Army). I've found some antennas, transceivers and powers generators for our vehicle, but would like to know what would you guys use. The frequency band is from 30 MHz to 3GHz cause that's the frequency range of our army's radios. So far we've been using L3Harris, Codan and Sentry for transceivers and TRIVAL ANTENE and HASCALL-DENKE for antennas. Any antennas (both directional and omnidirectional) and transceivers would be appreciated. Preferably with access to good documentation.

>>2800184

>tracked command post
Want to elaborate? Is it a circle jerk thought experiment? If not, are you just receiving? If not, how do you plan on being authorized to transmit on military frequencies? Encryption?

>>2800335
You can find these antennas on modern military vehicles

>>2800335
the double radiating element is for bandwidth

>>2800335
for example :

>>2800335
There are alot of variables missing here. LOS point to point communications or a network? Terrain? You sending data? Voice only? Frequency Hopping?

Military units have S2 Commo Officers that coordinate frequently management with both higher and subordinate units.

looking at an interface for setting up digital modes on my FT-1000MP
so far I've looked at the rigblaster advantage and the Signalink USB
I'm already setup for CAT control over a usb to serial adapter so I don't really need that feature of the rigblaster but it would help consolidate. Only problem is the rigblasters are backordered until late this year
I also saw the Microham microkeyer 3 but that's a little over the top
just the prebuilt db37 cable for the radio connection is over $100

>>2800407
>FT-1000MP
Check out XGG Comms. I have one of their units for the 891

Been down 2 days. Better that it goes down now than right after a major contest when everyone is uploading fuckloads of QSOs.

LOTW is maintained on an Commodore 64 I think

>>2800420
It must be a respectably sized database ... which bluntly is their main purpose for existing. If it wasn't backed up ... lmao

Can someone turn on 6 meters for the US? Thx.

>Want to elaborate?
Our army is replacing the M113 with VAC (Vehículo de Apoyo sobre Cadenas (Tracked support vehicle)). VAC hull is just the modernized hull of our IFV the Pizarro and a cousin of the hull of the new US Army light tank/assault gun M10 Booker. We say the program and decided to do our own command post version for the assignment. Piprel is mortar carrier version.
>Is it a circle jerk thought experiment?
Yeah, it's an uni assignment. Calculating uplinks, downlinks, attenuation loss, maximum transmission distance, etc.
>If not, are you just receiving?
Both, receiving and transmitting
>Encryption?
We are on our second year so we haven't worked with encryption yet but it would be nice for the project if the equipment could support it.
>>2800379
Omnidirectional broadcast for voice and data communication with soldiers and directional broadcast for between command posts to avoid detection. No LOS required. The terrain we use are both open fields and a mid sized city since our work project includes an urban deployment.
>Military units have S2 Commo Officers that coordinate frequently management with both higher and subordinate units
Do you have more about this? I've been working with this:

What's the class and this is strictly paper pushing, right? Thought experiment? No 'lab' where you try to do any physical testing?
Not being a dick - just a big difference between talking about transmitting on unauthorized frequencies and making an effort to do so

>>2800492
>What's the class and this is strictly paper pushing, right?
The subject is Telecommunication Systems and Services. Yes, a thought experiment would be a way to convey it.
>No 'lab' where you try to do any physical testing?
Correct

I'd read FM 11-55 Mobile Subscriber Equipment (MSE). It'll give you a good idea of system architecture.

>>2800514
Will do

so when upgrading from tech to general the FCC doesn't charge the $35 unless you're changing call signs right?

I'm in Europe, with 2 6M radios but no antenna. sadface.jpg

>>2800586

I got a 1,000 mile ssb contact on 6m today around 5pm pacific. Working fine.

>>2800407
I have a Rigblaster Advantage for my FT-847 because the radio doesn't do true FSK, only AFSK and it has a funky/faulty CAT system which complicates using data modes. The Rigblaster line came highly recommended for this radio because it simplified the cabling issues and is a quality unit. I lucked out when, after a couple of weeks researching and deciding I wanted the RB Advantage, 4 days later a guy 1 town over put his up for sale. Near mint, original box, docs, etc for $125 CAD. Even better, it came with the Yaesu cabling I needed.

Only used it a few times on RTTY, of all places on 440 MHz FM.

>>2800705
very nice
I pulled the trigger on the digirig mobile and for the price I don't think I'll go too wrong.
$96 for the digirig, cables, and shipping

It opened up later in the afternoon for me. Fiji (7,500 miles) and New Caledonia came through around 6pm. I was fussing here around noon.

Day 3 is in the books.
RIP ARRL.

Hey, /ham/, it's been a minute.
Does anyone have a mobile install? I have a surplus FT-8900 and a surplus FT-891.
I don't drive too much, but it'd be nice to have a radio to tag along. HF on long trips and VHF for local stuff.
The 891 would require running another cable for the microphone headset.
That shouldn't warrant buying one radio that does both, but the idea of juggling 2 headsets and 2 bodies and a tuner makes me start leaning to something like an ic-706 or ft-100d or ic-7000 - all of which are 'well aged'

>>2800919
Do an 891 and supplement with a baofeng hooked up to an external antenna. Take it out when you don't need it.

>>2800890
Paper and pencils exist, fagboy.

>>2800937
I usually upload to qrz first anyway.

>>2800944
l was listening to a ragchew the other day where boomers were flexing their fancy qrz pages
they actually pay graphics designers to make big text filled images for their profiles.
It's like Myspace over there

>>2800184
>There should also be some trans-only bandwidth allocated.
I've tried proposing this to our Government's communication authority.
The problem is that they weren't willing to allocate the several bandwidths (one for each color of the LGBTi flag) that I requested.
It might surprise most here but, even in 2024, systemic bigotry still exists.

some moron decided to broadcast fake signals from the ground that would cause aircraft to crash and made a blackhat conference talk about it
basically he made 4 fake aircraft guide the real aircraft into the ground through adsb anti collision
so what anon meant is they now have to verify the signal came from the air and not the ground

>>2801054

so why are digital voice modes on vhf/uhf tolerated?
shit doesn't seem very open source to me
dumb manufacturer lock in bs the boomers have bought line and sinker, half the repeaters in my area are fusion and the analog ones are dead as a doornail

I wanna thank chatGPT and their new 4o model which lets you upload images of circuits and it can tell you what it does.

>>2801209
you too? Just passed my general today
boomers must all do the tests on the same days
I didn't even get any of the circuit diagram questions

>>2801212
Congrats! Here in Sweden the local clubs either have planned test days. Or you contact the club and ask when one of authorized test givers are willing to schedule a test for you.

>>2801198
Does anyone else remember a simpler time when the ARRL stuck to mailing us furry stories?

>>2801219
November was a simpler time. Back when we had QST and a LoTW database.
Who knew how well we had it back then?

who had 'data breach' on their 2024 ARRL bingo card?

>>2801219
The ARRL has gone insane. I heard it was bad working there, but he's a madman.

Anyone having a good time at Dayton?

>>2801219
After this incident they're going to turn to a monthly subscription fee for the LoTW service.
