What was the most abominable pile of parts you've ever assembled that actually worked on the air? Here's a few o' me own: 1) Using the outer shield of a cable TV system for an 80 meter antenna. (Really needed to work HF while on vacation one year) 2) Open wire antenna tuners with alligator clip bandswitching....at 1KW. Several occasions. 3) NE555 timer chip with a 5th harmonic tank circuit used as a 160 meter transmitter 4) Using a grid dip oscillator for a BFO with a radio shack shortwave radio. 5) Open frame swinging link tank circuit on a 6 meter transmitter that I had to nudge back and forth with a twiddle-stick 6) Lafayette stereo amplifier (with germanium power transistors) used as a modulator for a Johnson Adventurer. 7) Using large filament transformers for modulation transformers (numerous occasions) 8) Using three cascaded filament transformers for a 6146 B+ supply. (Lot of those ancient mil-sped oil filled filament transformers could handle HUGE voltages....up to 100X their rated voltage) 9) "Full gallon" T/R switching using open frame relays. 10) Loading up the chassis of my Johnson Adventurer for an antenna on 10 meters.
