We only run V/S or L/S on AO-51 out of concern over damaging the SQRX
receiver if it were listening on UHF when a UHF transmitter came up. This
could happen with a battery watchdog event, or a software crash. Since the
doppler shift on the VHF uplink is low enough that you do not need to tune
on FM, if you have any sort of second VHF transmitter you could use it for
the uplink. Even a 5 watt HT will do fine, especially since we now use an
alternate frequency on V/S.
