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.

I was going to set up to receive AO-51 on VS when it occurred to me that I need the 144 band as the receiver for the S band down-converter. Then I remembered that I used to have QSOs on AO-40 with the same gear that I still have, but I do not remember and can not find any notes as what band we used for the uplink.
Will someone with a better memory/set of notes please remind me what band we used for the uplink?
