My FT-8800 is my main FM sat rig. It is the perfect 'mobile' type for FM
sats with the independent volume, squelch and tuning controls for each
side (band). Full duplex crossband works perfectly. I even have mine
rigged up with an external speaker/switch box with headphone jack. I can
plug in the headphones, switch off the speaker and talk full duplex
Having the 6 pre-program buttons on the front helps too. Mine is set up
so that when I press button six, the VHF side goes to the AO-51 uplink
and the UHF side goes to the downlink. I tune the UHF side as the
doppler changes. Button 5 switches to AO-27 and SO-50.
