A quickie on how the maggiore squelch circuit works. (when/if it
decides to.)
The five transistor chip is the heart of it, but not all of it.
The first transistor is just a linear amplifier.
The second is biased class C, and interacts a bit with the third.
The third is a little interesting,
The first tasks on a list of things to do/check:
If the squelch pot isn't a sealed unit, spray some Caig Labs
DeOxit treatment into the body and rotate the shaft around
a few times, then reset the squelch level and see what happens
over time. Many of the Caig Labs Spray would probably work
