Continued evidence that someone had their hands in this radio. Someone changed the unbalanced antenna connector to an SO-239. Fits well, but when they wired it in, they wired the suppressor in SERIES with the input, not in shunt. The 220k resistor was not connected either. Probably scratching their heads why their connector mod didn't work very well...........
I fixed it, tested the relay and reinstalled it. Glad I looked!!!!
