I had a need for a switchbox, to select between a number of low power radios... mostly boatanchors. Digging through the junkbox, I found a metal enclosure that was originally built as a multi-load t/r switch. I gutted it, made some changes, and whipped this up for $0. It now uses a non-grounding ceramic switch, and can select between 6 rigs, and has about 50dB of isolation on HF.
