Using NP0/C0G caps for better SSB stability? Was researching the problem of warm-up and freq stability in the Ranger/Galaxy radios. Came across a brochure from Murata that showed NPO monolythic cap stability compared to non-NPO caps. Since the Galaxy/Ranger radios use non-NPO caps in the oscillator circuits and the fact that the collective capacitance of that circuit determines freq and will shift wildly when cold or hot, thought I would bring it up as a topic. I was wondering if replacing the cheap ceramic caps with the NPO monolythics would tighten up the freq instability problem. They are indicated as the proper part in UHF radios for freq stability and aren't that expensive to replace a dozen or more caps in the radio's oscillator circuits.
