Is there someone out there who really understands the Ref Osc/PLL/VCO circuitry that could correspond with me a bit? I've gotten as far as VFO Linearization which won't run. Some tracing and measuring suggests some thing is wrong in this part of the circuit ... all RF levels are quite low, and some of the waveforms aren't what I expected.
I have a DMM, a Tektronix dual-trace scope, and a CTS 3000B Service Monitor. What I don't have is a good understanding of exactly what is going on here. My electronic design and troubleshooting skills dropped considerably with the invention of the transistor, and fell in the tank when IC's came along. Given the volume and diversity of traffic on this reflector, I think an off-line discussion would be warranted. 73, Fred K6DGW Auburn CA 530.885.8251 <[EMAIL PROTECTED]> _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
