Hi Les, I have an FCD (not Pro) that I use pretty often for satellites and a TS2000 for the main rig Given that the T and R bands are always different, and given that the TS2000 has separate inputs for U and V bands, I use a coax switch on each antenna (type N for UHF). One output of each coax switch goes to the matching antenna of the TS2000. The other goes to a U/V diplexer (again with N-type connectors). Then this goes into the FCD.
Of course there is some loss, but I have RF-switched preamps out on the antennas so that is less critical. 73, Burns W2BFJ Date: Wed, 12 Jun 2013 09:26:39 -0500 > From: Les Rayburn <[email protected]> > To: AMSAT Mailing List <[email protected]> > Subject: [amsat-bb] IC-910H Vs.
