[Hallicrafters] Need Help With SX-101 USB Problem

[rbethman]

Richard,

You have switch contacts that need to be cleaned.

Either use some TV tuner cleaner, carefully!  Or you, once again, 
carefully, get some DeOxit Fader Lube.

It is going to be a real PIA!  You may even have crystal socket crud.

Best of luck!  Most of us have been through this with all the old 
receivers and transmitters.

Regards, Bob - N0DGN

Any body have this problem & if you fixed it can you tell me how? I have even put a small fan inside & that does nothing .
