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...

Loving the new Richard II for the most part, but while changed values in the tech menu seem to be saving (and seem to be having the desired effect while in the menu, as in modulation level increasing), after the radio is powered down and powered back up, the effect is not applied in normal...

Pipe this invoice and tell me what you think. Keep in mind that some truck stop prices are actually cheaper for the exact same product than what DAS charged me for some of this. In particular, note my cost (unit cost column) and the suggested retail price (retail column) of the last item. I...

Has anyone else started having issues with Tram-Browning's support and general attitude towards product and customer support? I'm not ready to post any details yet as I'm hoping the situation can be resolved, but I'm very close to discontinuing all Tram-Browning products as a result of what's...

I'm sure I'm not the first to do this, but here's an idea for reusing those old SO-239-style antenna mounting studs. If the main body of the SO239 section is in decent shape, use a punch/vice or other method to drive out the "guts". Locate a retainer nut from an old CB or HAM radio's SO239...

This wasn't an actual contact, but PSK reporter shows I was picked up just off the Northern coast of Antarctica earlier today.

I acquired this as part of a lot of vintage radio gear (including some nice Heathkit transceivers that I'll put up for sale soon), but I have no idea what it is. My best guess is that it has something to do with a fancy crystal radio set. Anyone have the correct answer?

This is a very rough direct-entry frequency generator I threw together several years ago using an old telephone keypad, a cheapo 4-line LCD display, an Arduino Uno, and an SI5351 clock generator chip. There is no filtering as it was only intended to generate quick test signals to check for basic...

I have a Moonraker 4 beam antenna that was never installed for sale for $600. It includes all parts. The original box was deteriorated and had fallen apart when I obtained the antenna in an estate buy-out, but all parts were present. I've since put all of the parts except for the two longest...

I'm working on an S9 with controller board PCBX-0335R6 and can't seem to locate any newer info that what is posted on the CB Tricks website (that shows the 0335R. There is no frequency display, but the displays themselves test good when directly connected to a common ground and the segment pins...

I'm starting to get reports of Cobra's latest 29 Classic/Chrome series having partly blown displays, and the display Cobra is using is no longer the same as previous production versions of these radios. Does anyone know of a source for the part? I do not even have a specific part number yet, and...

I just made a contact with Rocket station in Stockhom on CB channel 2, 10:16AM today, from my shop radio in Carlisle, PA.. All kinds of signal on him!

I stumbled on this IC while looking at possible diode replacements for the venerable 1N34-style part. I haven't thoroughly read through the spec sheet, but I wanted to put this out for general discussion and feedback. It claims to have a forward drop of less than 100mV, which would make for...

Do any of you know where I can lay my hands on the channel display for a DAK Mark X radio? Thanks! More to come on this one as I get it working again.

What do you call a VERY large triple-gang potentiometer? A "triple-potamus".

Has anyone heard from Mike? I know he's alive and well from his QRZ page.

I have a Royce 619 base that needs PLL repair/replacement. I have the SAMs volume for the radio, but that doesn't have any schematic for the PLL unit, just pin-outs. I've been Googling, but no luck so far. Any help appreciated!

Yes, I'm speaking of Mark Sherman, dba Fine-Tune CB Shop out of New Mexico at the moment. Yes, he's got a good-sounding radio. Yes, he's got skills. But for the love of all things decent, respectable, and even just remotely nice, I am beyond sick and tired of hearing his incessant and...

I know this is an INCREDIBLY looooong shot, but I need a working VCO block for a Standard Communications model Horizon 29 CB (its the CB that was used in the truck from The Fall Guy TV series). It uses Uniden's PC-130AA PLL module which is a UPD857-based unit. The VCO is a wax-potted...

RadioActive Radios... That was a shop name that generated huge controversy and arguments a decade and more ago. I used to get many of their radios through the shop with requests to fix the assorted modification issues. When they shut down years ago, their radios showed up less and less...
