RS won't have DeoxIT. Other contact cleaners are poor excuses. Spray contact cleaners are NOT good for the radio leaving solvents in the insulators. Look to Antique Electronic Supply for DeoxIT, get

That is NOT DeoxIT. Tuner cleaner has always been crap at best. DeoxIT really works like tuner cleaners have promised and failed to deliver. 73, Jerry, K0CQ __________________________________________

Everything is based on the 10 MHz reference directly or indirectly. What I think you have done is messed up the 10 MHz multiplier and so killed the synthesizer. What you needed to have done was to ha

That's usually how oscillating RF stages are detected. Such oscillation often does affect operation by mixing in out of band signals and noise to obscure signals on the desired band. The question tha

The locals probably don't like gold plating very well, because cheap gold plate has less than half gold with other stuff to keep it hard but that oxidizes. Pure gold plate is often only a few molecul

Is the PTO jumper in place on the back panel? Does it tune on a band that is sure to have signals? If it tunes that jumper is in place, but the counter isn't seeing signal. There are two jumpers need

I'd think that the side thrust from running a finger just under the knob could be greater, and that if sometimes the hand griping the knob was supported by the knob more than the arm muscles that the

I like the aluminum knob I made for the PTO on my Corsair II. My lathe is too light to do a good job knurling so I don't offer it for production. Perhaps if I had a sturdier lathe, or made a knob to
