This page contains photographs of an 80m transmitter built back around 1997, the schematic, and records of some of the measurements made on that transmitter.
I cannot find the original web page that described this effort and contained these photographs. I know that it was in the archive copy from which I generated these legacy pages because I remember seeing it, but for the life of me, I cannot find it now, so I've created this one.
