[Amps] Alpha 87A Won't Transmit

[MU 4CX250B]

In my experience, UHF connectors, especially spices, often develop
corrosion and intermittent connections on the inner conductor. I’ve
discovered that if I undo a PL259 and look at the mating S0239, I can
clean a lot of carbonized goop out of the hole.
