Thought I would share this little annoying issue I have been fighting with. Poorly constructed USB chargers! These create so much electrical noise it can make your CB useless. I'm looking for decent 12v to USB chargers that won't make a radio go haywire. Anyone suffer from this issue?

It can affect scanners, too, especially those which are powered by USB. I’m not sure what to tell you other than to try a few out and see if you can find a good improvement.

Where do you think the noise is coming from? Is your CB powered directly from your battery with shielded cable? Any RF choke help at all? See if you can find a RadioShack 270-055 noise filter on eBay or wherever and test it out to see how much it helps. Assuming you can’t just find a quality USB adapter to replace whatever you’re using now, that is :)

CBs are always susceptible to various other electronics. Faulty power line transformers can wreak havoc on a CB. Florescent lights can really make one get noisy. When you activated an additional current flow by plugging in the phone, it seems to have raised the electronic noise level, thus making it raise above the squelch level. It's aggravating, but common. Increase the squelch and make sure the noise blanketer is on. But, only increase the squelch till it shuts out the noise and then, maybe, another quarter turn of the knob.

CB is always going to be susceptible to RF noise... because it is AM, and low frequency AM at that. As the others have suggested, snap on ferrite cores, Noise suppressors,etc. Proper ground is important also.

With some of my HF equipment that goes down to about half a megahertz i can hear electrical disturbances from all over the globe.

What brand radio do you have?

I am happy with it. Still works great and i use it mostly when I am on the interstate doing long drives, other than that I have my UHF/VHF digita/analog radio and scanner to keep my ears occupied while driving and at home i have a stack of radios and a couple shortwave receivers i futz with.

So you aren't fully into the HAM radio world? I like the company because you can leave the radio at home and log into an app/online and listen in from across the world.

Yeah i am into it. I like DMR and such. I just moved to NC and use my DMR radio and a hotspot to talk to all my friends back in AR, and also use a network of 35 linked DMR repeaters and talk from tennessee to georgia to Virgina and all over NC. I've also got and SDR dongle I can access and tune the receiver remotely via the net from 24 mhz to up in Gigahertz range.

It's always nice meeting another HAM Fan. Kudos.

Been one for 25 yrs now.. have always enjoyed it. Some guys are all about HF, I am into higher freq's and different modes. Do a lot of satellite listening and signal chasing late at night. been hooked on shortwave since I was about 8.... so a bit over 40 yrs now. I've did Earth -Moon-Earth bounces and gabbed with people on the ISS and got to meet one of the Astronauts I talked to at Hamfest a cpl years ago (Doug Wheelock). I am just a signal geek.

Also a ham but old timer - had to learn CW to get my license. Drive to the Chicago FCC office to take tests above the Novice license. Have some 'modern' solid state radios. But have a 'few' tube radios like Collins KWM-2A / 312B-5 remote VFO / Collins S Line. Mainly on 220 MHz at times. Take care Spin

A VHF guy huh? What goes on up there? Mostly an HF guy. Also curious, how many watts can the unit transmit?

I use to be on HF a lot - but tower got hit and top pipe was welded to the tower for a bit. IF / When I move to a larger lot. Will again put up something. Have two 43 ft verticals to put up. One is a 'short' 80 meter top hatted discontinued Dx Engeering DXE-80VA-3 antenna. Have worked 125 countries - worked John ON4UN on 80 meters more then once. Using a gray line calculator - worked Guam on 80 also. I started in ham radio way before computers. Back when RTTY was state of the art comms.

Collins radios use a pair of 6146's. "The Collins KWM-2 is a high quality amateur band transceiver featuring CW, LSB and USB modes. Frequency ranges: 3.4-3.6, 3.6-3.8, 3.8-4, 7-7.2, 7.2-7.4, 14-14.2, 14.2-14.4, 14.8-15, 21-21.2, 21.2-21.4, 21.4-21.6 and 28.5-28.7 MHz plus additional 200 kHz positions for 28-29.7 MHz. Power input is 175 watts PEP on SSB, 160 watts on CW. Power output is 100 watts PEP nominal (slightly lower on 10 meters). Features include: multi-function meter, crystal controlled high frequency oscillator, and a highly accurate analog display with Fiduciary Adjust. 14.75 x 7.75 x 14 inches 18.4 lbs."

They where not cheap - think a KWM-2A / Power supply and 312B-5 remote VFO was about $2800 USD 1970 (2019 $18,484) Collins had the best crystal filters around. The -2A added general coverage outside of the ham bands. Plus they made a mobile power supply and mounts for them. KWM-2A was used the US Military - had a suitcase to store and transport them in. (when I dig up my old 1978 AES catalog - will double check the prices.)
Take care
