[TenTec] Corsair II going deaf!

[Stuart Rohre]

Indeed, if there is an aux antenna switch, or contacts on the linear relay
to ground out the receive line during linear use, you might have corroded
contacts in need of cleaning.   Caig products such as DeOxit or whatever
they call it now, or simply pulling rough bond paper thru the closed
contacts is often enough to give a relay a new lease on life for the
contacts.
