The crystal is 1.8432MHz. This puts out a square wave into a divide-by-5
The 8 pin DIP is a Microchip PIC12C508. With a 22Hz RC clock (the pot is the R)
it puts out a slow morse code, with 3 second DOTS. This square wave fed the RESET on the other divide-by-2. The /5 output feeds the /2 input.
This output is buffered with a couple of TO-92 devices, which drives a LC filter
I get about 20V P-P Sine wave from the LC filter when tuned just right.
I think I'll drive a couple of TO220 devices with this, then the HUGH
coil-form I have hanging on the wall, and the ganged capacitor (1000pF).
