Ok, I got a new project that showed up this week, E-bay estate sale. Pretty clean. Receives AM well, very quiet on the white noise static side, meaning if I drive around town I am not getting noise from stop lights and over head low power lines. I do not have transmitted audio. The mic it came with was a white rectangular hand power mic with aqua colored cord, no battery so I am using a stock Midland coffin mic. When I key the mic I hear a click from inside the radio and the RF meter on the radio swings backwards. However I have clear voice through the PA when I hook a speaker up. Planning on making an appointment for the old girl at the docs. My guess is someone had it dead key way to high in the 1970s. I always wanted an old SSB radio for the homestead collection. Got it in package deal with old JcPenny SWR/Watt Meter. Old back of set antenna, Radio Shack Power Supply. I do not claim to be a tech, as always all opinions welcome.
