[ARC5] BC-221 and LM Solid State Conversion

[Robert Eleazer]

I found an old article I had saved on converting the BC-221 Frequency Meter to solid state and also a little info on converting the LM frequency meter in a similar manner.

I scanned the material and sent it to David Ross for his website but for those of you who simply must have a solid state BC-221 up and running by sundown contact me directly and I will send it to you.

By the way, I could not get the circuit to work with my LM, but have not tried it with a BC-221 yet.
