Help with SatPC32 and Dual Radios
Ok, so I am fairly new to SatPC32 since leaving my old setups....
I have dual FT-847's setup as follows:
FT-847 - TX/RX UHF, RX 2.4ghz (down convert to VHF) FT-847 - TX/RX 2m
So, I setup SatPC32 for two radios. Both radios are being controlled.
Issue is it is fine for V/U, but then on a U/V SAT it has the frequencies flip-flopped.
In other words, I think it always uses RADIO A for uplink and RADIO B for downlink?
Is there a way to change/fix this behavior? I want U on the UHF radio and V on the VHF radio.

Mike,
Is there a reason you want to use two FT-847s instead of just one?

Michael, you want to use one radio for RX and TX on VHF, the other one for RX and TX on UHF. So, I suppose you have the VFH antenna connected to one radio and the UHF antenna to the other. You are right, normally Radio 1 is always the receiver and Radio 2 the transmitter. So, if you switch between V/U and U/V sats it would be necessary to switch the antennas, e.g. using a transfer coax switch. To avoid this disadvantage check option "Autom. Rx/Tx Change" in menu "Radio Setup". (Leave all other options in the menu unchecked). This feature will change the roles of the radios as Rx and Tx. If -e.g.- radio A is the Radio 1 and connected to the UHF antenna it will be the RX with V/U sats (Fo-29). You can tune the radio around the passband and radio B will follow. If you switch to a U/V sat (AO-07) radio B will become work as the RX. You can tune it in the passband and radio A will follow.
This feature works only if you switch between v/u and u/v sats, not for other bands like your 2.4 GHz downlink. Then you will use the radio with the downconverter for RX. If the uplink 2 m user the othe for TX, if the uplink is UHF use the same FT-847.
