I’ve got a Cobra 148 GTL mobile setup, with a spare coax. Say I wanna buy an antenna to put on the side of my house and do a base station setup to get the most range I can possibly get. What kind of money am I looking at?

wow you guys are really going ham

Epstein files proved it: antenna jews want you to waste your money on DXing. Don't give them your money to do it.

>>2974189
so... I'm not supposed to give my money to the "antennajooos", but I am supposed to give it to the "wirejoooos"? you don't make any sense,

>>2974214
You don't get scrap wire? I got thousands of feet just from cutting off cords from vacuums people are throwing away. And it's all free.

>>2974159
How would I find out if anyone in my area had ham radios that I could talk to without first buying a ham radios to listen in first?

>>2974280
Buy a cheap RTL-SDR and start listening in.

>>2974159
I read these threads and watch S2 underground and everything looks too complicated. What would I need, why would I need it, when would I use it?

How long is the 'really long wire', is there a specific ratio to run from the cuck shack, or just as long as possible? Does the tree interfere with the signal?

>>2974280
See >>2974281 and https://haminfo.tetranz.com/map

Also look at repeater book and program put in the frequencies into memory on your sdr.

A long wire antenna is a really crappy antenna. It does the job, but it's terrible at it. Depending on the length, it'll be better at certain bands. Go with a half wave with the band you want to work the most. The long wire meme I fell for when I first started (all you need is 100 watts and a wire.) I couldn't get anything on 10-17 meters. 20m was a pain to get any contacts but I got them. It wasn't until 40m when I got some decent results. Got better results on 80m. 160m I did have minimal results with ft8, but they were terrible. I don't remember the length I had it.

That image is wrong on the unun. What you want on that one is a 49:1 since i. You go 9:1 if you have a counterpoise which makes it a random wire instead. Also, unless you have it up in the open, you're going to have an object interfering. Even then, things can interfere with it still like someone's charge controller for their solar panels on their house since almost all of them spit out dirty RF. You just do what you need to do to minimize it like, again, putting it out in the open.

what is cheaper to run a cb radio with without problems? (at home)
charger -> car battery -> radio
dedicated radio supply -> radio

>>2974215
so you are stingyjooo.

>>2974322
A dedicated power supply. Chargers are RF noisy. If you're running legal power CB, all you need is a 3 amp PS.

>>2974331
ok. as i understand, a linear power supply is best.

now i think this cb is txing 21w with ssb (president grant export, 120ch(3x40), roger beep version)
so, if i count correctly i'd need at least 2 amps on 13.8 volts which gives about 27 watts
would this work?

I know nothing about base stations for a CB.
I’ve got a spare coax, but when it comes to antennas, and dipoles and whatever- I have no clue what I’m doing. Like if I wanted to reach out as far as possible, would I be fine mounting a 102” whip in a tree or something?

It's dangerously freezing outside. Stop starting fires and making people homeless just to make yourself feel relevant.

Got my first coms, some old uniden UHV handhelds.

Still not really sure how to use them. Push to talk is easy enough and I can set the Channels on the general use bands without much issue. It's squelch just to dial out interference?

These things can do far more then I expected, so I'm not really sure what to do with all these extra features.

i finally managed to receive some 1200 baud POCSAG here in France. with my trusty QuanChang uv k5.

anyone knows more about this shit?

for example:
there is a message which repeats every minute between 35 seconds to about 45 seconds of the minute.
"TONE ONLY" and its in the numeric type.

then you have a few messages around the minute 56 seconds or 02 that said 946 but these came about only 4 times and they use the alphabetic mode (alpha)

assuming i'm decoding them correctly it seems like no one is even using this shit so the "TONE ONLY" is like a heartbeat.

nonetheless the IJV firmware includes a BYP (bypass mode) which outputs discriminator type audio (disables de-emphasis so decoders can interpret the messages correctly) and the messages seem to be captured.

since the "TONE ONLY" message sounds the same all the time (same length and as far as i can tell, same thing) and that it comes in at around the same time. i suspect no one is using this anymore.

anyway i'm glad that i can finally decode some digital stuff with this radio.
firmware version: IJV MOD 3.60

>>2974483
cont:

i think the problem is i was monitoring only one frequency.
there are 6 and they don't behave the same it seems.

How?

>>2974508
me know how... me want chance.

so, should i just build a collinear coax antenna?
it has fat omni-directional gain and is cheap for a poorfag like me.

the antenna jew wants me to pay probably 300 when i can make it for 15
whats the catch?

btw. put this in the sticky

Labor: building, testing, and tuning. Also, owning the equipment to build and test.

>>2974634
of course.
i still have to get an swr meter and an antenna tuner, other than that i have almost everything.

anyways, why is this "coco" coax collinear antenna not shilled more?
apparently many repeaters use more advanced variations of the collinear antenna (folded dipoles etc) because of strong horizontal omni-directional gain.
it seems like a no-brainer no?

So all these guys on CB that’s coming in from halfway to across the other side of the US- do they all have like really expensive base station setups or something?
I’ve got a 102 whip with a Cobra mobile setup, and nobody can hear me clearly,

They run 10 meter amps into beams. Either 100 watts or a low thousands of watts. This is not allowed by the Part 95 rules but nobody is coming for the keydown crowd.
