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...

I've been puttering around with end-fed half-wave antennas for 40 through 10 meters (concentrating on 40 for now), and have had trouble coming up with a good match-box design. I've tried different ideas from an array of online sources ranging from auto-transformers in various turns ratios to...

I have a Magnum Omegaforce S45 in working condition, selling as-is for parts/repair. Transmit level is around 30-35 watts, receive seems to be very good. Meter functions test ok, but I haven't tested every microprocessor function. Physical condition is fair to good, with the face having only...

I have a 2510 in tested and working condition that comes with an original Astatic D104M Minuteman mic. The mic still has the original plastic barrel-style battery hold INTACT, with a fairly fresh lithium battery installed. The radio's physical condition is good, and all button functions have...

I was just made aware of an Ebay listing for the Cobra 29 LX which is a verbatim copy of my own listing (with the exception of the price - this guy is claiming to sell the 29 LX for $39). The listing in question is located at Cobra 29 LX 40 Channel CB Radio | eBay. The listing from which this is...

He goes by Roberto Renta, and Cielo Renta. Known email address is crenta@aol.com. His shipping address is in East Elmhurst, NJ. He comes off as a big spender, but in the long run, he's cost me a heck of a lot more than he's spent, in the form of lost potential customers and lost revenue, etc...

I don't know if this should be in the controversial section or not. I thought it was funny, and not particularly controversial. Anyway, while I was doing some research into how websites and domain names are valued, I found the Radioactive Radios website listed in an online website evaluator. I...

I'd like to look at a thread posted on the CB Radio Talk forum, but I've been permanently banned from there by one of its sponsors, namely Radioactive Radio. The thread link is http://www.cbradiotalk.com/viewtopic.php?p=165360&sid=6e5bb8b542a7101894533278d6d13b0d If someone could take a peak...
