Don't go throwing your money to the antenna jews just to DX.

I have a 102” whip. I was trying to tune my SWR earlier, and channel 1 is reading 2.0 and ch 40 is about 1.5
I also have a barrel spring. How am I supposed to fix my SWR?

>>2939614
How are you grounding it? Does it stay like that consistently (e.g. same on sunny and rainy day?) Unless you are transmitting often, 2.0 is not really that bad.

>me and my bud buy cb's at radio shack when we were 16
>start talking on the cb channels to each other while delivering pizzas
>BRAKER 1 9 BREAKER 1 9 THIS HERES DUBYA D 40 COME IN
>the truckers start getting mad and yelling at us on the radio
>we keep trolling them for a week until we get bored of it
good times

>>293962
I am grounding it. How well the connection is- I don’t know.
Ch. 1 reads 2.0 and ch. 40 reads 1.5
I thought you had to have those 2 pretty much the same.

>>2939620
This was for you. >>2939622

are there any bands that you arent supposed to listen in on? aircraft/military/etc? or is it pretty much public domain but illegal to transmit anywhere outside hobby bands

>>2939614
From Cobra's Website

>Check the SWR on channels 1 and 40.If the SWR is lower on channel 1, then the antenna is too long. Make the antenna shorter. If the SWR is lower on channel 40, then the antenna is too short. Make the antenna longer. Continue to adjust the antenna until the SWR is approximately the same on channels 1 & 40 AND is less than 3. The antenna is now properly tuned for the CB band.

I added 12" to my 102" whip to get 1:1 on 19 lmao

>>2939651
>>2939614

Using something like Picrel will get your 102" to 108", the true 1/4 Length of 27.185

>>2939651
I’m sorry- a foot? How in the world am I supposed to add a foot to my antenna?

>>2939648
As far as I know, it's only illegal to listen to analog phone calls (which have not existed for well over a decade) and to decode pager messages (which are surprisingly common)

>>2939653
This is why I'm purposefully not buying an SWR meter I'd rather just live in ignorance and pretend that everything is all good on both of my rigs

>>2939653
>>2939655

>Adding one foot

>>2939656

>>2939656
I’m sorry- like literally mounting it a foot higher?
>>2939655
Can’t you damage your radio though?

breaker 19 this here's swollen prostate!

the chad scanners

>>2939614
cobra SWR meters in their radios are notoriously off.

>>2939746
I know, that’s why I bought an external one.

>>2939735
I guess if I was going to damage one of them it would have happened by now, it's not like it's anything crazy, just a van with a cobra 26, 15 ft cable, and a fire stick mounted to the ladder on the back door, and a cobra 3 in my car with another 15 ft cable and a $15 Walmart CB on the trunk lid.
Like, I'm hoping it's all standard enough to just work as-is.

>>2939735

Yessir, do the math to figure out 1/4 Wavelength of 27.185MHz

It is around 108.35" or so(Number off the top of my head) but in my case, the rear door of the truck messes with the antenna and that's why I needed more than the spring and six inch extender.


>>2939746
As to the SWR Meters in cobras, they are junk and purely Gimmick but I tuned my Whip with a Nano VNA

>>2939808
Man, I didn’t know antennas were that sensitive. That’s absolutely insane. I really don’t want to add another foot to my antenna.

harmonics? or is this that "DX" thing?

>>2939874
>rtl-sdr
not sure about your question, but i just got 2 of these things and have been listening to the cops in my area with them
its pretty entertaining listening to them
>negress in a mercedes license comes back suspended
>cop lets out big sigh on radio
>you can hear his fatigue is maxed out off the chart
lmao i feel bad for the cops i hear sometimes.
any other cool shit i can listen to with them?

>>2939880
planes and shit at around 127 mhz (AM, they all seem to use a push to talk system, so its a waiting game), and the national weather service radio stuff (NBFM, ~162Mhz, should see them around there) parently you can also pick up weather satalites but i havnt been able to pull any in through the window yet tho, may need a diffrent antenna or an amp and a filter

>>2939874
I’d guess it to be your SDR is seeing an image of a powerful signal out of your mixer, which is likely the case since I believe cheap SDRs use square wave mixers with all the 3rd 5th etc. harmonics that entails. If you can find out what your local oscillator frequency is set to, you can calculate what images such a mixer would create. The LO is probably 30-36MHz judging by the RTL dongle bandwidth, putting its third harmonic in the 90-108MHz range, slap bang within range of the FM broadcast band.

>>2939887
>artifact of the archatecture
ah ok

>>2939886
>planes and shit
yeah i have listened to them but im not close to a busy airport sadly
I didnt know about the national weather service stuff tho, thanks anon

>>2939648
That depends on your region. Some countries block segments of the RF spectrum or outlaw it entirely from it's citizens. Here in Canada you can receive any RF signal you detect. The only stipulation is that you can't reveal the contents of the signal except when subpoena'd by the Crown or as requested by the Communications Minister, and you cannot benefit from the communications heard.

>>2939880
How do I find out what channel the cops are using around my area? Maybe I could add it to my GMRS radio and snoop on em sometimes

>>2939648
It depends on the laws in your country, it can be forbidden to listen to some bands, or legal to listen but forbidden to retransmit by any mean (youtube, broadcast, discussion, etc.) what you listened to.
I don't think that, in the western world, someone gives a fuck as everything that shouldn't be listened to by civilians is ciphered

>>2939891
>yeah i have listened to them but im not close to a busy airport sadly
No need to, you can listen to the air traffic control specific areas, you can use https://skyvector.com/ to find these areas and the frequencies in the VHF band are indicated on the map, use the different levels of fly (world hi, world lo, VFR...)

Why would you use this instead of a 4:1 or 1/4 wave of 75 ohm line to a tuner with an actual resonant loop? You already have the height. Could also do a horizontal loop on 80m and have 10-80m virtually resonant or within 3:1. This vertical is dogshit. You can make a fan dipole and configure it as an inverted V too on 5 bands that would blow this dogshit random wire vertical out of the water. Or do an extended double zepp, or any kind of doublet.

>>2939874
Harmonics and dogshit unusable front end filtering.

>>2939898
i used radioreference.com/db/browse/
it has pretty much everything you would need to know

>>2939910
stale

>>2939966
>Harmonics and dogshit unusable front end filtering
I think it's the harmonics of the square wave local oscillator, hard to filter those out when the LO can go from 25-1700MHz.

Stop creating hurricanes just to make yourselves look important.

>>2939614
2 is ok.
Allegedly you wont damage your equipment until closer to 3.
I mean it lowers your range, but w/e you dont seem like a minmaxxer

>>2939648
If its old analog, they wont know if you passive listen
If its new digital, it'll be encrpyted & you wont be able to listen

> as everything that shouldn't be listened to by civilians is ciphered
lol. govts live off reputations far more than reality.

>>2939874
I dont understand what the context for this image is. Is Transmit power -60, and off band is -70? Offband noise level should be ~70db below transmit level, not 10.
There definitely do look like some periodic spikes; I'd zoom in on one see how bad it is.

>>2939898
Easiest way is to know somebody
Second way is FCC license search.
3rd way is govt. agencies publish stuff all the time; in a mountain of paperwork

i have a bunch of rtlsdr's
sdrtrunk to listen to p25 police
kismet for adsb
its nice listening without all the fuckin broadcastify ads and they have some nice software for streaming

>>2940082
>2 is ok
Thanks anon. That’s what I read as well. I’d like it to be at peak performance, but I really don’t know how I could raise it a whole foot.

>>2940089
Its an inverse relationship, so more return loss doesnt help you a lot.

At VSWR of 2, ~90% of your power goes out.
Lets say you bump that up to 100%. Thats less than 1db of gain.

Id be more worried about damaging the equipment, which you prob wont. Look for gains elsewhere.

>>2940090
Oh wow, that’s basically non existent then.
I really appreciate that. I guess if I’m still into CB’s in a year, maybe I can buy an amp.

i hear we might be getting a near 6meter freq for gmrs

>>2940097
Only proposed. It's be great if they added in digital modes to GMRS and ability to legally link repeaters. Maybe if they add 6m to the license, they can legally crossband link the repeaters together using one of the 6m channels. Not that any of that matters here since everything is dead except for the ham repeater with the same asshat OMs using it all the time talking about their last medical appointment.

>>2940079
because cell phones are radios used to talk very long distances, these idiots want to use RADIOS to talk long distances... maybe... if the weather is good... if there is someone on the other end... if their prostate isn't acting up.

>>2939910
it's "muriatic" not "muratic"

>>2940133
>if their prostate isn't acting up.
Fuck. Thanks for reminding me that I need to take my finasteride, anon!

i agree ham is largely gay af i dont want to talk with random men let alone a bunch of boomers cause that was all the rage before computers and internet in every home the rules governing it are ancient and overly restrictive id much prefer a chunk of every ham band be sectioned off for unlicensed anarchy then it might get some use

the only time theres real activity outside a few rag chew repeaters is during faggy contests where reddit-esque normies try to collect the most callsigns/hellos in a weekend

no one want to make random statements over the radio while also doxing themselves with every fucking thought

>>2940079
decentralized communications that can't be censored by corporate monopolies
communications that are resilient during emergencies without requiring infrastructure
scientific purposes like communicating to amateur weather balloons, satellites, ROVs
scientific studies of things via radio propagation, like weather, sunspots and the ionosphere, or tracking mh370 or bouncing off the moon
learning about radio itself by way of making and upgrading your equipment for greater signal strengths and distances

the first point is half moot because you are compelled to identify yourself and to not obfuscate information, but there are definitely ways around that second point on digital modes by hiding encrypted data within common compression methods
as for your identity, ham radio isn't the only method for transmitting information wirelessly, you can use existing protocols that don't need a license like lora
if you're extra paranoid you could write your own lora-like protocol with a significantly different chirp-style and frequency range so you can transmit long distances below the noise floor without anyone having the idea to look for your signal, just avoid the deep space network

>>2940248
>decentralized communications that can't be censored by corporate monopolies
laughs in squarey wavey broadybandi jammies

>>2940249
governments can do that sure, but corpos probably won't
both govts and corpos can control your internet and phone comms

That's just radios + repeaters.

Can anyone tell me why no one takes larpers seriously? Oh wait, no one does. They need to bring back Doomsday Larpers to remind people again how they need medicated. I always love making fun of them and much more so when they have meltdowns when it comes to hams.

>be me

Don’t think anyone could hear me. I tried asking people if they read me, but I don’t think they could hear.
Also- if I can pick up someone loud and clear from California for example, could they hear me if I’m all the way on the east coast? Or would I need an amp?

>>2940404
where I live, I have left my CB on all day for weeks on all the popular (non superbowl) channels and hear almost nothing. I've gone on trips and almost nothing even from truckers.

>>2940448
yes you will get more contacts putting a phone number on a rest area stall than a cb radio in 2025 just do that

>>2940401
Ah shit. Not a phoneposter, I got the (dead) and (embed) bullshit out but forgot about the youtube link.

Thinking about mounting a CB in my house with the microphone rubber banded on next to a bluetooth speaker or some shit playing music from my PC and then driving around in my car and seeing how far away I can hear it.
Not like anyone's gonna give a fuck I've had the radio for months and never hear anything, not even near the highway on Ch19.

>>2940674
>2200 m
Good luck with building this dipole!

>>2940571
use your own brain and decide.

>>2940674
Never used them, even with an acre of land I couldn't possibly reasonably string up a 630m antenna.
>>2940676
You really won't be using a dipole for 630/2200. Because the signals are so weak, and because you'd need such insane height, most agencies that use these frequencies use some type of curtain array or good old beverage antennas for reception. Otherwise, you won't hear jack shit.

>>2940676
I think in an earlier thread we found that the Golden Gate bridge would be an excellent base for such a dipole. What could possibly go wrong?

>>2940706
Hams will always experiment. One of them should do it even just for the lols.

theres already a jewtube ham fag that hikes around and uses anything metal as an antenna to transmit on

>>2940770
Yeah, ham radio tube with a G90 as an experiment to see what the G90 cannot tune up.

Has anyone tried Baofeng radios? Are they good? I wanna get started in amateur radio and they told me Baofeng radios are cheap and effective and have low power.

>>2940901

>>2940901
I have some put up for emergency use in the neighborhood like the time a guy had a hunting accident and the time when the power was out for along time which I handed out for the old folks if they needed anything. Otherwise, they're absolute shit.

found some non english speakers using what i presume is a miltary sat as a repeater lol

>>2940986
Eastern Russia and South America are nicely covered by the couple remaining ones

>>2940901
Any walkie talkie is shit, get on HF.

>>2940986
'found' LOL
thats just the old P-band satcom
meritards figured it would be a good idea to launch sat repeaters that cover from 240MHz to ~300 or so, without authentification and just bank on no one ever noticing.
Well that aged like milk so they launched new ones with auth.
They either cant derail the old ones of keep some backup. It's not really like you interfere much if a warship poibnts an antenna up there and blasts it.

>>2940302
Lol you fucking faggot. Its called "pirate radio" for a reason. Think i give a fuck if some boomer triangulates my nazi propaganda? He can look down the barrel of my shotgun as I tell him to get the fuck off my land. Only faggots register with the government. And yes I do play hitler speeches overpowering the local NPR and liberal media. ;)

>>2940901
>>2940902
both are great affordable entry level radios to realize that the only people you will hear from are boomers in assisted living homes with nothing to do and no friends and it only costs you sub 50$ (to buy both) and not 500$ super het kenwood/icom slop

>>2941158
You're better off getting a real scanner, because all you'll hear are old fuck boomers, and that's all that will hear you as well.

>>2941159
If they go with a scanner, might as well go up and get one that can all band and SSB so he can hear the dumb boomers on 80m talk about their latest colonoscopy and antennas. But at that point, might as well get an SDR and listen to it from his computer.

>>2941160
Most scanners will do ssb, and he really wants p25 phase 2 simulcast compatibility so he can hear all the feds, cops, and wendys employees.

>>2941162
>Most scanners will do ssb
not only will they NOT do ssb. they also don't receive below 54mhz.

>>2941162
>Most scanners will do ssb
name them

>>2941165
the expensive ones only boomers can afford saving a few months of ss checks

>>2941163
Most scanners do ssb AND receive well below 54mhz.
>>2941165
BCD325P2
SDS100
SDS200

Basically any SDR you'd hook to your computer (RLT-SDR being the cheapest I know of) will also handle full blown trunking as well as ssb. That said, the front end filtering is non-existent and the knowledge curve for operating sdr software is extremely steep.

>>2941163
>they also don't receive below 54mhz
Don't most scanners receive cb radio? That'd be below 54mhz.

>>2941170
Name them.

>>2941172
>most scanners
can only list 3 of hundreds.

the 3 listed cannot do SSB.

meanwhile a 20$ dvb usb dongle can do just about anything

is there a readable table of frequencies that weather satalites downlink on that satdump can decode?

>>2941183
All 3 can do ssb, in fact my bcd325p2 does it from the box. Try again.

>>2941219
Nope, either sound boards or hearing digital modes illegally used on cb. It happens all the time, none of the cbers give a shit and neither does the fcc.

>>2941219
They're freebanding by going between the CB frequencies.

>>2941239
the sds100/200 and your bcd325p2 cannot do USB/LSB/or SSB. they can do AM, FM, NFM, WFM, or FMB)

your bcd325p2 cannot even tune anything that would be transmitting SSB.

there are no scanners that can do SSB.

>>2941299
Scanners only do AM on the aviation bands and CB.

going to an airport event this weekend got my cheap laptop, 2 rtlsdr's 1 scanning the airports tower/ground/approach+departure freq's using rtlairband and a 2nd dingle listening and plotting ads-b transponders using kismet

>>2941339
and if i add up the costs of this setup its like 150$ dongles+laptop just need to pickup a cheapo inverter to keep the laptop charged and a large microsd card to record it all to disk using obs

>>2939599 (OP)
I wish Ukrainians would bomb that piece of shit

>>2941160
>so he can hear the dumb boomers on 80m talk about their latest colonoscopy and antennas
Would you hear an 80m signal with a cheap scanner antenna? Probably not...

>>2941395
uhm... idiot... it's in Ukraine.

>>2941302
yeah no shit.

>>2941403
So many ways. The easiest: long wire crimped onto an alligator clip onto the metal antenna. String up the wire. It doesn't have to be high to receive. I've ran it through some low bushes before and got 80m. Mine? I just have my SDR attached to my rain gutter. I just took a SMA male jumper, split it in half, spliced a long wire onto the coax wire itself, soldered it, taped it, heat shrink, ran it through the hole fir all my cables and attached it the gutter. Attach the sma connecter to sdr. Audio received. It's not good, but it does the job.

Shit is not complicated if you are just listening and don't care much for audio quality.

>>2941408
I was clarifying for the trolls and retards, assdick.

hell, finding a cheap cb radio with ssb was a bit of chore last time i tried

>>2941480
no one could tell that.

OK, I said fuck it and pulled the trigger on an SI-4732 thumbmaster 3000 and a connector SMA->BNC->BNC->Screw terminal block for shits and giggles.

How good are they compared with full size "real" radios like the PL-330 or so?
I'll upgrade the firmware and I asked a bro with a 3D printer to print me a lime green shell. Anything else I could/should do?

I mainly bought this for quick & dirty experiments with nigger-rigged wire and other antennas. Like
>get 30 feet of thin braid wire, wrap it around a Harbor Freight bucket and see what happens
>Jumper cables - your truck's unlikely loop antenna
>Doc Shortwave live from the local iron railroad bridge

Also: Does anyone here know why the Lilygo T-Embed SI-4732 has LW too but no SSB while the ATS-Mini SI-4732 has SSB but no LW?

>>2941586
probably a different chip or missing software chinkshit isnt known for quality control and not cutting corners to save yen im not familair with this soc myself

>>2941436
So the answer is no, you wouldn't hear 80m with a cheap rubber duck scanner antenna, and would need a long antenna capable of receiving a decent 80m signal. Got it.

>>2941612
generally yes need a very long wire (away from any interference producing electronics) and a propper ground things that handhelds are very poor at

notarubicon told me that gmrs is the way for portable handheld comms
