Martin is exactly right. Two of the same things is only partial redundancy. In order to be fully redundant the two systems must be independent, built by different teams and have different technology. We can't afford to stumble on this. It seems to me that Mirek has already solved this problem for us.

I do not agree that Mirek has solved this for us. The L band receiver is not an analog transponder. There needs to be an interface block between the receiver and the follow on transmitter to provide gain control, impedance matching, buffering, etc.
Mirek COULD solve this should he choose to.

the same way: you send signals here, they receive them there.
The only difference is that there is no cat." - Einstein
