[TenTec] Pegasus xmit problem

[Denton]

I had the 20 meter section cease xmiting on my Pegasus...turned out that one 
of the relays on the bandpass filter board developed an open circut on the 
relay's coil....I think, since I used the rig on 20 meter psk predominately, 
that the coil wire simply burnt open.
Both the input and output relay's coils are in series with one another, FWIW
