It’s a sunny, balmy day in Western NY, 34 deg F. The snow melting encourages the Deer in our back yard to feast on the grass underneath.

"The slugs are so sensitive that it will convince you telekinesis is real". That should be a hall of fame nomination quote IMO….:ROFLMAO::love:(y)

Another enhanced service manual and redrawn schematic of the Lafayette Dyna-Com 12A. Our Civil defense team once used these and other Dyna-Com 5 watt variations. I remember many of the proud owners treated them with great affection. Custom carrying cases were the norm. Other than occasional...

For your archives, this is my redrawn President Zachary T schematic with an enhanced service manual.

Thanks! That’s great! All the other stitches have been successful. Now I can complete the schematic without guessing some resistor numbers and values.

I need a scan or photo in the gutter area between page 23 and 24, CB 122 Zachary T. It doesn’t need to be clean or perfectly straight. The total schematic is going to be stitched together and redrawn as time permits.

Taken from a previously posted scan, this is a revitalized service manual of the Pace CB113 with a redrawn stitched together schematic.

This is a recent enhancement of the Midland 79-892, service manual, plus a redrawn schematic.

This is a recent enhancement of the President Madison 1010002, service manual, spliced schematic, plus a stitched together block diagram that was redrawn.

I see a pair of UA741 OP amp chips. That leads me to believe it is probably a mic compressor or preamp. Tracing back all the connecting leads will tell the full story. For rigs back then that didn’t have that function, various compressor add-ons became popular. Usually connective wires to bypass...

This is my enhanced version of the Utac TRX-500. Many horizontal lines were redrawn and the LED and PLL section was completely redrawn for sake of clarity.

Enhanced version of CB-19 Demco Deluxe service manual with separate schematics.

Thinking about making your own? I’d try Zazzle. They have a number of different designs at reasonable prices. Midlands C.W. McCall’s logo among others comes to mind. https://www.zazzle.com/create_your_own_add_image_custom_text_round_clock-256187880550476176

I was surprised to see that Pace thought it was necessary to apply a fan in that rig. Enhanced version of the service manual with separate schematic.

This brings back fond memories 22 years ago with Venus Hum and the Blue Man Group on tour. She is one of the best cover artists IMO.

No, both have similar parts, but not the same board.

Couple that POS with a QRP rig for an ultimate challenge. LOL

You might try something like these LED dome lights. I suspect they would be too bright. Adding some series resistance to each of them would solve that issue. Finding the ideal resistance value will take a little experimentation. I usually start high like 15K, then I work my way down from there...

Thanks for posting your thread! I once added a few small (half the size of a pencil eraser) capsules salvaged from several defunct Chinese walkies. Those were gold plated, including the short leads. I figured since they were gold plated, they had to be of higher quality than normal. I was very...
