CB Radio F.A.Q.


  • Where should I buy my radio from?

Check out your local CB Shop for new items, as well as garage sales. Of course Amazon and Ebay can be very helpful.


  • Why can't I hear anyone/anyone hear me?

Make sure that your antenna is fully plugged in and that your radio is receiving power. If you just installed your radio, you will want to make sure that your antenna is tuned properly to the location that it is installed in. This helps reduce the standing wave ratio (SWR) to proper levels.

An SWR of 1:1 is perfect and almost impossible to achieve outside of a lab.

1.1-1.5:1 is considered perfect under real world conditions.

1.6-2.0:1 is Average with room for improvement.

2.1-2.9:1 means you need to tune your antenna some more.

3.0:1 and above is dangerous for your radio and could lead to damaging the radios internals.


  • How do I know what my SWR is?

You can use one of two methods to check your SWR: an antenna analyzer or a stand alone SWR meter.

Both are acceptable, but the antenna analyzer is the best method, giving more accurate results. Any good CB shop will have one.

CB DX'ng

Today on the local graveyard I received a lot of CB radio signals from very distant parts of the world. And I wondered about it!

Mobile antenna as base antenna. Resonant at 23 MHz

I have a 5ft Firestik antenna that came with a radio I got used. I want to set it up as a base station antenna for someone else. I don't have much control over how much I can do in terms of outside installation at their place. I just did a sweep with my NanoVNA, to see how it reacts when used indoors, close to a window. I attached a counterpoise of about 10 ft long. My NanoVNA shows it is resonant at about 23 MHz, which is way off. The adjustment screw at the top doesn't have much effect. Is this to be expected? Should I write this off as an option? I've posted about this scenario before but never really tested the Firestik as an option.

Audio Audio If you're gonna spam anything into the void why just repeat auuuuudddddiiiiooo over and over.

All that being said it's been a bitch to get any confirmed contacts on cb. Fun to listen to guys with 5000watt stations nearly blowing my cheap little radio up when they come in.

Been having fun learing though

Spanish skip

Back in the day, I used to read the Spanish off the back of spray paint cans when trolling the South American skip that clogged things up so badly. I would call myself the "Loco Gringo"

I even got a few comebacks once I started running a russian ceramic tube amp that would swing about 4k when driven by my Emperor TS5010.

It was very satisfying to actually get them to reply.

27.685 KHz Spanish LSB

27.685 KHz (the ATS-25 reads 27.683, it reads 2 KHz Low in LSB). Spanish language Freebander probably located in Southern California or Mexico. Received in the Pacific Northwest, USA at 17:30 UTC (10:30 AM Local) 2 NOV 2024. Spanish operators seem to favor 27.600-27.800 MHz and 26.500-26.700 MHz.

Receiver is an ATS-25, connected to my homebrew 'Lil Stinker passive preselector, then to a 65 foot end fed random wire antenna.

Kl203 or kl203p?

Is the preamp worth it on mobile ? Even with a radio with nrc it will increase the noise floor and require more fiddling with rf gain and squelch.

Any reason to spend more for preamp vs just kl203 for TX?

Wanted to install a CB/Scanner on my truck, Ran into a problem...

Ok so i drive a '19 F150, and i wanted a scanner in my truck as well as a cb. I found the Beartracker 885, and i just ordered one. However it said a bunch of stuff about different connectors and i have no clue what any of that means. I found a antenna mount for my 3rd brake light that mounts it to the top center of the vehicle, which i think is the best place right? Anyway the whole question is that if this: https://bulletproofdiesel.com/products/third-brake-light-dual-antenna-mount-2015-2020-ford-f150?pr_prod_strat=e5_desc&pr_rec_id=5e1205890&pr_rec_pid=4768682999904&pr_ref_pid=2264799379552&pr_seq=uniform
will work with both the CB antenna and Scanner antenna. Will i need to call and get different connectors? Is Coax for both ok?

Maybe overkill?

I’m trying to get some long range out of my bearcat. I found someone local selling this 7 foot firestik and I mounted it on my jeep. I am getting insane reception yet no call backs aside from a guy maybe 15 miles or so away. How do I get out further? Do I need more power? (within legalities of course!) my radio is a Uniden Bearcat. Astatic “amplified” microphone. None of my coax is bunched together. My antenna is mounted to a mount that screws between my tail light housing and the body at the quarter panel so hopefully this is enough of a ground plane. Any advice is greatly appreciated!

What is the deal with the annoying rubber chicken guy? I can hear him on my whole trip from Nashville to Dallas.

I turn squelch up and he can break that sometimes. It is so annoying I turn my cb off sometimes.

First Set Up

I am new to radio and looking for some insight. I am interested in a radio for my pickup truck. Mainly to just play around with and listen on while I’m on the road.

I’ve been looking at the president mckinley as I think having SSB might be beneficial, though I’m not sure I need it. Price point isn’t too much of an issue.

Will a 4ft antenna be sufficient? I’m either mounting the antenna near the tailgate or doing a fender mount on the hood. I’m looking at either a firestik or maybe hustler hq27. Any suggestions on antennas would be appreciated.

I also see 10/11 meter recommendations. For my intended use, regular CB is probably fine right? Is it even worth having SSB?

This set up will mostly be used in the Midwest, though I do travel south sometimes. I’m not sure if region or the topography will make a difference in what I should be looking at.

What goes into this antenna mount?

Found this Cobra 18 Ultra at a thrift store complete with a power supply for 7 bucks, couldn't resist my eternal urge to get one of those.

Bracket for Antenna Installed on House

So I am having my antenna installed soon and I'm getting worried about wind and the thing becoming a deadly weapon. :) I bought a Solarcon Antron A-99 and this bracket.

https://www.amazon.com/dp/B0BMQ2YKPC?ref=ppx_yo2ov_dt_b_fed_asin_title

Will this be OK or should I look for something more heavy duty?

Thanks!
