[amsat-bb] Adding an SDR Receiver to home station--Hardware Questions

[Scott]

Hey Les!

I also have 2 dual-band radios and a variety of SDRs that are used in
various combinations with the different antennas coming into the house.

Perhaps my approach is simplistic, but I have female BNC adapters on the
end of each run of LMR-400.  There are short jumpers available from each
radio & SDR terminated in male BNC's.  I just connect each radio or SDR to
the appropriate antenna depending on the needs of a particular satellite.
 (or combination of satellites when they are clustered close together)
