Conditions seem to be peaking at this time. While adding a few extra crystals on an old 23ch Royce 606 I hollered for a radio check on ch26 AM. 3 stations came back immediately, all giving me strong signal reports. No amp, just 3.5 watts with my Imax 2000 antenna. Pipe line between Western NY to...

That last photo is a beauty. SUV manufactures must be watching this closely with a keen eye for their next advertisement. Who will take the trip first, the Toyota 4Runner, the Ford Bronco or possibly the whoop-de-do Subaru Forester?

After previously being introduced to microwave resistors on this forum, my next dummy rebuild will consist of a single 50-250 (50 ohm, 250 watts) dry dummy with a large heatsink . My rebuilt Cantenna is still functional, but if the resistor ever starts to deteriorate, I’ll use four of those...

We sold a ton of those back in the day. A lower priced basic radio like your 1-600 made them popular with first time buyers. An enduring survivor that’s also easy to repair or restore.

I don’t know about the issue you have with the touch bar or if it even could be fixed, but I once mended a broken one for a customer by gluing on a custom name badge tag. In that case, it covered the damage plus added some personally.

PLL 02A PTBM058COX Cybernet board radios were made approximately 1976.

For clarity I drafted your schematic. Let me know if I made any mistakes, if so I’ll correct them with a revision. I wasn’t positive about a few components that were bleached out. I don’t have a 5 volt relay at this time, but will try this circuit sometime later. Thanks for sharing.

I believe the 13-857B has the same Cybernet PTBM039AOX board as the 13-882C. Many small variations of this PLL 02A abound. The following is the schematic and pot adjustment points. If you need further info on the can adjustments let me know.

I usually use several programs to rejuvenate large schematics, but in this case it was done with Paint Shop Pro X by copying and pasting the various symbols taken from a template. The fonts and connecting lines is a product contained within Paint Shop Pro. The image is then cropped, reduced to...

I took the liberty to make this printable schematic for the archive.

Midland had 3 versions of the 13-882. This covers the earliest “plain version” that CB tricks omitted. The stand out feature in some of these early crystal matrix radios are the two transformers some of them utilized in the audio chain. I found this particular radio a little strange concerning...

I wonder if you replaced them with flat head tamper resistant screws. I remember those were common replacements on stall doors.

Congrats Hogs! Our family was rooting for you Wally!

I had no idea the hinge screws in my toilet bowl lid were so valuable.....

You could purchase one of the many DNA Tests for dogs. Although pricey, just like humans, it’s useful information for medical personal in identifying possible genetic health issues.

Agreed...I stopped using sleeve fans every since most of the early computer fans started producing the rattle of doom in short order. Sleeve bearings tolerate very little blade imbalance due to dust or debris and need to lubed more often. I have a 20 plus year old household ball bearings box...

Thanks for sharing Claude! That’s one of the few Cybernet board schematics that I didn’t have.

I noticed that CB tricks have scans of the factory manual, but I thought that the Sam’s version would help complement that archive. I once owned the Tram 60 when they first hit the market. Even though I received my dealer’s discount, I remember how it affected my budget for month’s afterwards...

The original 23ch Cobra 29A is still alive and well because of quality parts and good workmanship. Part of that longevity is also credited to the far lower amount of hacks preformed back then. The occasional crystal swapping for extra channels was about the only mod done. The prolific number...

That's called fighting inflation with your Costco GoldStar Membership....
