I have a CXB UHF repeater and can't get the receive VCO to lock properly. I get a peak of about 23 uA but it doesn't lock there. If I tune to where it will lock, the M5 reading is about 13 uA. I've taken the VCO apart twice and cleaned it.
Is substituting the transmit VCO (which does lock at 38 uA)a valid test of anything? I've also posted this problem on the MSF-5000 group, but no answer so far. I'm probably in the market for a replacement VCO if anyone has one available. Suggestions would be appreciated. 73, Howard WB4GUD
