[TenTec] Paragon question

[Bwana Bob]

I find that if I have a relay problem causing low receiver sensitivity, 
I can fix it by transmitting (into a dummy load) on the ham band for the 
relay in question. A few pushes of the tune button or a few strings of 
dits at full power cleans the relay contacts and restores proper operation.

You're right, though Scott, the long term fix is to change the relay.
