I consolidated your Zip into a single modified PDF. As usual I spliced together the schematic, and put it in a separate Jpg file. The high resolution of your original scans were great, but the circuit boards would have turned out a little clearer if they were scanned in at least 256 grayscale...

A short time ago in the midst of Covid, some people started raising chicken in their garage, just like they did in during the great depression. People stole ketchup out of restaurants to make tomato soup for their families. People jumped out of high rise windows. So much for the stock market…...

Our short haired bully sheds a lot too. Breeders trick: Disposable gloves help collect that hair. Dogs love a rub down and most of the hair will attach to the glove from the static it produces. Hairs along with the gloves are then tossed in the trash afterwards. A win win....Just another tool...

Al Pacino....If I were the man I was five years ago I'd take a FLAME-THROWER to this place!

In the first place, the Cobra coffin or any other typical 500 ohm mic is not a good choice for that radio. That Swan needs a HI-Z mic. cartridge. An early HI-Z Johnson or Shure mobile mic will work.

By comparing the photo of your board with the schematic, R472, R473, R474, are missing. Oddly they left behind Q47 and other associated components. They essentially completely disabled that circuit by removing those 3 resistors. Do you have the missing knob? Otherwise I’ll look to see if I...

Just finished my modified enhanced service manual along with a separate spliced schematic. If you find a crystal that's out of tolerance, go to page 3. For faster reference, I often include the crystal layout frequency with associated channel chart.

It does have a modulation indicator. I saw it on the schematic. It's embedded in one of those small boxes along the top of the channel selector.

Thanks Dan......In about a week or less I'll post the enhancement and schematic splicing.

Another model "Delta Tronix D1325RF" was listed in CB Tricks, but that page is blank of any info, and I didn't find any other reference to that particular model on the web. If I get a copy of the manual at some point, I'll list all the models with photos on the cover page. Of course I'm hoping...

I don’t have book Sams 132, but I think this could be your rebadged radio. These all have slightly different face plates, but the same layout in the following models. D-1325RF is the key to all of these examples and they can be found on Ebay. Ebina Lake D-1325RF BOHSEI EBINA Model D-1325RF...

This is one other Smokey CB that I found that somebody posted on Facebook. The face plate layout is different, including a Smokey the Bear logo. I never saw one of these before. Wish I had an inside view. At any rate, these early 23ch matrix radios are not too difficult to troubleshoot and...

I would also be glad to do some research if photos were provided. 23 channel radios are kind of my thing. Anything to be gained? You have nothing to lose by trying to solve its origin. You can almost bet there is a clone. In the rare case that nothing is immediately found, I’d still place...

With our Royce dealership, the 606 and the 600 was among the early 23ch radios we sold. Except for size and features, both had similar 37Mhz crystal matrix circuits. Royce also used two transformers in their audio chain. One thing you could say about their electrical engineers, for better or...

As with most of Western NY, no special glasses were necessary. We had very heavy cloud cover all day. Except for all of the small businesses in the Buffalo area that raked in big profits, many viewers were somewhat disappointed. Nonetheless, at least for me, it still was an experience to...
