Well, I was rummaging through my countless parts bins and found a whole pile of miniature DIP single pole double throw relays, with convenient 5 volt coils. I was wondering to myself,"Self, what should I do with all these relays?" And Self answered back, "You should build a precision ladder attenuator or two or three for your direct conversion receivers." So I agreed with Self, and I will start on this project. The only question is how do I want to encode these relays...Or should I configure them to simply switch in attenuation in 3dB steps across the entire range. Decisions, decisions. Stay tuned.
