Comet service manual.

My enhanced version of the schematic. Service manual to follow...

As a novice back in 1964, I discovered that My Heathkit DX20 operated as a QRP rig. In the “Grid Tune” position only the 6CL6 oscillator will function. This all came as a big surprise to me one day while practicing code. Stations started to respond to my practice session….. Oops!

This is Thunderstorm Artis singing his version of “Blackbird.” I’ll never forget this cover song he did on the Voice back in 2020. I was also pleasantly surprised hearing him perform again the other day on American Idol singing “Island Style.” After this, I’ll probably buy one of his albums...

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.
