You can pick up cheap FM transmitter on eBay and Amazon now. You'll have to hack up an antenna though..

The key to proper "loud" audio is using a compressor/limiter to feed the exciter. Consumer units will be fine.

Transmit in mono for a little better range on the signal, unless you need stereo for music, etc.

>>2434047
many national ham organisations have emergency teams that set up long distance communications when normal means for communications are destroyed or unavailable. There was a major fire in a small town around here, all base stations were eitehr lost in the fire or lost power (and the emergency generator ran out quickly). It was up to the ham teams to set up working communication systems.

Most hams I know are ex mililtary guys who are trained for emergencies.
>>
>>2434769
let's go for the 500W amp ? Anyone elese interested ?
>>
>>2434711
The simplest way to get started is to use a Si5351 which is popular in SDX and similar radios.
A DDS is harder since you probably have to use a FPGA, but an open soucre example is the RadioBerry.

Amazing resources Anon, thank you for yet another negligible out of touch boomer contribution to my hobby.
Now all I have to do is source components that went out of fucking production half a fucking century ago and have a shelf life of about 5 years, and require a full transceivers worth of support circuitry in order to barely function then overheat.

Just wire an resonator to a CW key and antenna and there you fucking go. Bonus points use a crystal so you don't pollute the spectrum with your shame. If you really want to be pretentious use a TCA 440 to build a robust receiver. If you absolutely have to, wire the two devices with a relay and build a transceiver.

How can I measure dipole resistance? Can I measure voltage and current directly?
>>
>>2435367
What equipment do you have available to you?
>>
>>2435387
a scope and a multimeter. i set the mm to ohms but it measures open circuit, not 73 ohm.
but i am not sure, since it also has a reactive part so it is actually 73 + j42, is it supposed to read 84.2 ohm (the magnitude)?
>>
>>2435431
it is open circuit in DC, what your multimeter measures.
the impedance is at a specific frequency
>>
>>2435452
But the half-wave dipole impedance is 73 + j42 of which 73 is resistance and 42 is reactance (if is positive I assume it is capacitive).
Reactance depends on frequency but resistance does not. The meter should be able able to measure the resistance. Or I could use a scope. That's not the problem. The problem is I don't understand how to directly measure voltage and current in an antenna to get the resistance (or impedance). I probably need to connect it to some sort of circuit.

Build an impedance meter like in https://www.w5big.com/QST_Article.pdf
>Can I measure voltage and current directly?
That's exactly what early hams did, measure voltage and current to the antenna system at certain points.
Old QST articles should show you these configurations.
Back then I think they's optimise the matching network for maximum current.

Bought a house a month ago, saw two antennas on roof that realtor thought were lightning rods.
once I moved in and took a closer look saw they clearly weren't.
neighbor told me previous owner was a radio operator for the coast guard a long time ago, was a big HAM radio fan and took it seriously and that he "didn't buy cheap stuff".
Found three lines from them coming into an office/radio room (otherwise empty) that was build into the garage. Two coax and one thing I can't figure out.
Little info, my only experience with HAM is my wouxun kg-uv8d. I have never ever been in the same room with "real" equipment.
I'd really like to take advantage of these antennas and buy some equipment to use them with. Any ideas on what to buy, how to hook up, etc.

Wow why is it that device so complicated? Two generators? Heterodyned? Why cant' you just feed a single signal and measure voltage and current as a voltage drop on a sense resistor?

So I got a weird question. I wanted to get into airsoft milsim to larp and fuck around, just to get out from my house. And in these 'milsim' events they use radios to communicate, is it possible to eavesdrop the communication on enemy teams? What if they have encrypted radios? I really want to listen to the enemy team. Is it possible to hack them?
>>
>>2437167
If you know their frequencies yes its possible. But that's not assuming their using dtss codes or anything. Then u just have to guess. Encrypted radios I highly doubt anyone is using that shit at a milsim event. Hack them?

The hard core stuff is locked down with the same thoroughness as cryptography. Some info can be found in the /cyb/ FAQ, latest version is this: https://files.catbox.moe/9e5dgm.zip
The /ham/ FAQ has a FAQ too, the OP text.
A few bits and pieces are scattered around the net such as https://irp.fas.org/doddir/army/fm3-36.pdf

>Sounds fun.
EW is the intellectual for for warfare, where the operators are the quiet, the calm and the competent. This costs them a lot of medals as the "Nintendo medal" debacle demonstrated.
>>
Bros I have a question. Im a new ham and I only have tech license for now, and use a Yaesu ft60 ht for 2m and 70cm. Another ham gifted me picrel and I was wondering if I can use it to talk on the 2m repeaters around me. I ordered an SMA/PL259 adapter to hook it up. Just wondering if the HF waves coming through the antenna would damage my ft60 at all.
>>
>>2437624
The BaoFeng is the standard shitty issue UHV/VHF radio out there... I have three collecting dust under my desk right now.

First things first, judging by the few comments i assume you made i assume you're not a radio operator. And that's completely fine. But id start with some basic RF stuff. Frequency(es), antennas, receivers.

A good entry point is ARDF(amateur radio direction finding). This will get you probably 90% of the way there. You can use a highly directional antenna to pick up on "enemy" radio transmissions, and get a rough bearing on the direction it's coming from. It's reasonably simple to do, and could guide you in to more advanced stuff.

Now HAMs can get kinda wacky with how seriously they take their hobby. But in reality, if you have a Baofang, tune it to your 'enemies' frequency, and use a directional yaggi antenna to get a rough bearing on their direction, have a long range rifle and binoculars, you will be miles ahead

Like anon said, real EW and ELINT stuff tends to be hush hush, and the precision equipment and calibrations needed make it a bit out of reach for the every man. But some fun stuff can still be found declassified from the second world war, that's now achievable on the cheap.

It's the equivalent of the enigma machine. Sure any competent cryptographer will shit on it in minutes, but it will run miles around your average larper
>>
>>2437677
>>2437650
Cool stuff man, thanks for pointing me in the right direction to get started.
>>
>>2437676
Neah, just make sure the antenna is set up for 2m. If you leave it set up for HF, it will feedback and ruin the transmitter.

Unless you're right next to another antenna transmitting in HF received power shouldn't really be a concern, transmuted power feedback though an unmatched antenna can be a real problem however
>>
>>2437676
That's a nice portable antenna to be gifted, anon.
And yes, VHF/UHF with the FT60 should work. If you want to be really careful, get a VHF/UHF SWR meter. Or try it out with the lowest power setting and go up which each transmission.

Also add male or female. There were many female sparks in the merchant navy, the shore stations and the military, several of them also hold a ham licence.

Got the meme dongle.
Are there any decent resources for identifying signals?
Obviously there are certain things broadcast on certain frequencies, but some of them could either be weird interference, or a signal I simply can't decode.
For example, there were solid always-on signals in a couple ham bands I checked. Can't be a normal broadcast, right?

I've been using SDRSharp, but the recordings cap out at 2gb, and it seems like the audio recording setting can not record multiple slices. Should I be using some other software if I want those capabilities?

>Are there any decent resources for identifying signals?
Sure, there are links to SIGINT resources in the FAQ.

Drove down on the I15 south of salt lake city, Utah, towards las Vegas, and came across 20-30 of these vans and trucks (truck has the same gear and glowie plates) with government license plates, ~10 antennas on top, and were mostly spread out a out a mile between each, and occasionally I saw individual ones stopped by a freeway exit alone. What might they be doing? Each driver had a big radio set up by him as well.

99% of 'women voices' on the radio are just prepubescent boys. The sound is indistinguishable.

Had that white thing been spherical, it would have been a steerable satellite dish. Since it is truncated it most likely is a direction finding antenna, typically an array of ferrite antennas embedded in epoxy.
>>
>>2439708
That's really bizarre. Is the black vehicle a Bearcat? As
>>2439863
said it's a direction finding array, so really all people can do is speculate what glownigger shit they are up to. If it is actually 20-30 vehicles that's a lot of resources to divert towards locating something so it must be important. I don't think there are 20 people in the entirety of the FCC enforcement bureau to begin with so very clearly this is some other glownigger agency looking for something.
>>
>>2439864
Actually I think I know exactly what this is. Based on the location you provided this is probably some type of counter drug trafficking operation. Mexican cartels utilize all forms of radio communication for their operations including both standard two-way VHF radios and more advanced systems like transponder beacons (similar to APRS) and even more sophisticated systems like Pactor III HF modems. Considering I-15 is a major drug trafficking corridor they are probably monitoring or attempting to locate something cartel related.
>>
>>2439868
10/10, would believe
Last year on HF somewhere between the higher ham bands you could hear a file transmission between two made-up South American callsigns using Robust Packet.
>>
>>2439874
In the higher level cartels some people come straight from the military so they bring their knowledge of RF communications with them. That or the CIA hooks them up with something. They are very sophisticated when it comes to communications. There were some photos of a Northern Mexico cartel with a PACTOR III modem hooked up to an ICOM rig but I don't have it saved unfortunately.
>two made-up South American callsigns using Robust Packet
I've heard something similar as well on 60 meters which was two people speaking Spanish using FreeDV. I don't speak Spanish so it could be anything but the conversations weren't something you would typically hear on HF with a lot of nonsense inserted between them. No callsigns, no boomer lingo or Q codes but instead what sounded almost like their own version of a phonetic alphabet and grid locators. Again could be anything but judging by how out of place and atypical it was it's probably exactly that.

Also I'm sure everyone has heard of the decommissioned UHF SATCOM satellite thats hijacked by South American drug traffickers and radio pirates

Possible. As an alternative it could be an exercise, possibly commissioning new equipment. The terrain is reasonably flat so DF bearings should converge nicely. That would explain the large number of vehicles involved when you normally just need 3 - 6 stations.

Could be Galician fishermen, although that ID gets thrown around a lot. You can hear their banter all over. 60m is secondary to maritime radio, too.
>FreeDV
That's funny though.
>>
>>2439864
Black trucks weren't Bearcats. They were a ram 2500 or Chevy Silverado, I don't remember.


Thanks everyone for the thoughts on what it could be. It was killing me. Wish I had a memefeng or something in the wife's car I could possibly scan with.

Yaesu FT-2980R only 2m but you can do 80w so it would be great for emergency use. It's a bit over budget but I got mine on sale a few years ago for about 120$.

Have my general class, never did anything with it other than local repeaters/DMR. Somebody gave me an old HTX-100, but I need a power supply. What's something cheap I can get started with to see if I even enjoy talking with boomers over HF? Like Baofeng tier or slightly higher, if we're making a comparison to radios.

Stupid question incoming:
Bought an old crown vic cop car and its got an nmo mount already installed in the trunk and miraculously the retards didnt cut the mini uhf connector off when they decommissioned it. Problem is its been exposed to the weather uncovered for who knows how long. Do I just say fuck it and slap an antenna on it and go or replace it? Its gonna be a chore to run a new cable to the console so I'm very inclined to not do that but I've heard that water intrusion into these is a problem. I am in the south so I figure if any gets in there its just gonna evaporate out?

If you're transmitting, and have weird or wonky swr readings, yes. If not, it's fine. If you're just listening with no Tx, I wouldn't worry about it.

>>2440371
just fix the psu?

It needs an external power supply unless you wire it into a vehicle

I know, that's why I was asking for fucking recommendations!
>>
>>2441621
It's a bot, don't reply to it.

What voltage does it need? Any desktop 13.8 volt power supply should work but if you need specific recommendations I can give you one.
>>
>>2441660
Also I looked up some stuff for it online and there are AC wall adapters for what seems to be powering it. If you plan on using it for HF it might be a bit difficult considering 10 meters has very spare propagation and it looks to be more of a CB radio. But it's probably worth giving it a shot considering 10 meters is the easiest to work on HF.

>>2441663
>if anyone is interested.
I am. This looks like advanced wizardry.
I had hoped DSP tech such as MIMO and beam-forming would come to /ham/ also at lower frequency bands, but the sheer complexity of 8 x 8 arrays seems overwhelming.
>>
>>2441731
I have had a big crash course over the past week or so since the thread has been up, which is kind of why I bought the thread here. We all get to learn some cool shit. There's at least two towerfags lurking that thread, if you have questions, now would be the time.
>>
>>2441735
I got my license years ago, later did some DSP work and some years after that did some mobile phone tech stuff. With this it is easy to see that there is a lot of mobile phone tech that could be ported to the ham radio world. The truSDX etc. use more fancy tricks for SSB modulation, but MIMO and beamforming are still not here. A simple 4 element would go a long way and help with the ever increasing QRM problems.

Yeah I saw that in the manual, but beyond that, trying to actually pick out a power supply is pretty daunting, so I'm looking for kind of a generic bang-for-the-buck recommendation.
>>
>>2442137
I see now you're actually retarded.
>>2442149
get a Astron if you want a (linear) supply that will last forever. You could find a used RS-7A or 12A for around $100 or less. MFJ has a switching 15A supply for $95. I have a 3 Astron linear supplies RS-[7a, 12a, 20a]. I bought them all second hand and I've had them in service, myself, for over a decade with no problems. They're not small like a switcher is, though.
>>
>>2442295
Thanks AN0N, I'll look for an Astron. I don't really care about size, and I'd rather not have to worry about RF noise with a switching supply. Any suggestions on where to look for used equipment? (My local hamfest is this weekend, so I'm going to stop by and see what I can find.)
>>
>>2442315
Hamfests always have them. Just watch out for equipment that has been through floods. Ebay isn't bad if you take your time (like browse for a couple of weeks) and jump on a good deal. People will unload them for half price there, however watch out for the shipping as they are heavy.

Are all BNC male connectors the same and the only difference is the ferrel diameter? Why don't they sell generic connectors with a set of different size ferrels? And another question I have, I have this here RG316/174 crimper but I need to crimp a thicker cable.
What happens if I crimp a larger ferrel with a slightly smaller die by pushing gently to avoid squeezing it too hard?

The inner diameter allows the core of the coax to enter the connector so there will be differences
If you use a smaller crimper it will be badly crimped and might separate, make a bad connection, etc etc

It is. However, that is highly specialised skills. Since OP asked, it was obvious he had no such training, and therefore he would not be able to evade triangulation. The /ham/ FAQ has some information on what systems are out there to find people like OP.
