All:
Multiple receivers and transmitters/transfer switch remains an open item. There have been discussions, but no conclusions. Some who need to participate with me in that conversation have been unavailable for a while. We'll get there.

John,

Sounds like a good plan!  But we probably need a "system" command 
decision - right?? Is this something project management can buy into, 
assuming we don't run into serious issues with space or weight?

Don't think power would be impacted since the spare unit would be in a 
power down mode.

Since only UV supports the text mode with omnidirectional ground 
station antennas and this is the only linear transponder that operates 
over 75% of the orbit, I hope that we can fly two V transmitters and 2 
U receivers. Each pair of receivers and transmitters could then 
connect to their gain and omni antennas via a transfer switch so that 
there is no single-point failure mode.

Hello Bill!

In regards to the RF distribution circuitry, I count 8 users of the 10
MHz clock. Help me out here if I missed one....

1) V Transmitter
2) U Receiver (maybe two?)
3) L Receivers (two)
4) S Transmitter
5) S2 Receiver
6) C Transmitter
7) IHU
8) Spare (for X or K beacon or a "contributing" customer)

(9 and 10) - SDX processors

73,

Lyle KK7P
