[TenTec] Omni VII RX AUX socket

[demerson]

The Omni VII has a socket for a receive-only antenna, the AUX ANT.

1.  Is this socket switched on transmit, or when in use is it 
permanently connected to the OMNI VII receiver input?
2.  How much stray RF power can be allowed to reach this socket during 
OMNI VII transmit?  More than 10 dBm?
3.  If the N4PY mod cables are installed, to allow use of a 2nd 
receiver, does that affect the answers?

   Unfortunately the simplified block diagram in the Omni VII manual 
doesn't show enough detail to answer these questions.

      Thanks,
               73
