Yes, in the default mode, PCSAT has the transmitters cross-connected to both TNC's.  SO if either TNC keys up, it keys up both transmitters.  The idea was that this was a failure recovery mode so that we could get a command link to either TNC in case either transmitter failed.  Once we had command, then we could disable tthe crossconnect.

Duh... but not if the reason you got there was due to low power.  We can command the isolation relay, but then we loose it 45 minutes later when we go into eclipse and we are back to crossconnected.
