I've had several Galaxy DX model owners calling to find out if Galaxy is still honoring their warranty even though they are basically out of business. The only information I've gotten is through conversations with suppliers and service shops, and it looks like Superior CB in Ontario CA and...

A truly classy person doing an equally classy thing... 12:28 PM 8/28/2026 at the Sunoco/Subway right beside exit 52 off of Interstate 81 in Carlisle, PA. He was apparently parked out in front, right by the entrance and maybe 30 feet (if that) from the restroom. This guy literally walked all the...

Thank you all for your replies and thoughts! I knew I couldn't be the only one facing that dilemma, lol! Interesting idea on the guitar picks, never thought of that! I usually carry about half a dozen guitar picks or so in my wallet in case I get a chance to play when out and about, but I think...

For thirty+ years I've tried to find coil adjustment tools for everything from miniature coils in certain RCI models (even smaller) up to the larger coils found in some very vintage ham gear and CB's. The ones I have the most problems with are the ones found in a typical Cobra 29 LTD or Galaxy...

I have the schematic, but no way to scan it as it is too big. I did my best to photograph it for you.

Glad you got that figured out! Even with biasing slightly high, you should not have seen that much runaway current so quickly.

Glad someone posted that question! I've often figured there was a special tool for that, but since I never had any problem using pliers to do it, it was never a big deal. Now that I've seen the tool, I'm probably going to expand my tool kit.

Cobra used to have a repository of all their schematics on their website, but I can't find the link anymore. I've contacted them to see if it still exists.

You will want to document signal levels at different points in the transmit circuit chain when the radio is operating properly, then compare them to the ones you see when it falls off. This should narrow the problem down quite a bit.

Please add me to that drawing as well!

I've never seen this brand or heard of it. I'm guessing its one of those little niche brands that popped up to take advantage of the huge CB craze of the 1970's. The maker is Asahi Denki Co, LTD out of Japan. The radio works well, and was even made with a standard 3-pin power connector like a...

I didn't see any brand as such, just a few cryptic alpha-numeric characters that I didn't think to photograph. Pretty sure they just spelled "shite".

Partly agree with you on that; however, I have encountered factory systems that actually worked quite well for a few years before needing to be replaced. Some, of course, are utterly useless and should be replaced immediately. In some cases, the over-all system is fine for years with proper...

I 2nd the NMO idea. I keep those items in stock for that very reason.

I had a customer this morning with a Freightliner Cascadia tractor that turned out to have a bad antenna. This system was an external, single-antenna setup. Most customers keep their old antennas so that when they leave the tractor/company they can re-install it and keep their good one. This...
