IFR Com 120A synthesizer unlocked
Posted: Fri Feb 21, 2020 2:44 pm
I have an IFR Com 120a that initially wouldn't keep its generator locked much below 80 MHz nor above 995 MHz. Now it appears that the geneator won't lock below 200 MHz. I've had this problem before and all it took was cleaning connections and putting the unit back together. I've done that and still have the same problem. There are no signs of leaky capacitors. Everything else seems to work; including the receiver, function generators and, so on. My thought is there is an adjustment somewhere that needs to be tweaked? Any ideas?
I've reached out to a couple of service centers; one said send it in and, the other has yet to respond.
If nothing else, I may just sell the unit and quit fixing radios.
