Re: AO-51 Mode



Hi John,

As versatile as AO-51 is, we are limited by the hardware on the satellite. 
We have two UHF FM transmitters, one 2.4 GHz FM transmitter, three VHF FM 
receivers for users, and the SQRX receiver which is usable on FM or SSB on 
VHF, L Band, and with poor performance on 10m. Other limitations are that 
digital uplinks must go to the SQRX receiver, whatever audio is fed to the 
435.300 transmitter is shared by the 2401.200 transmitter, and due to 
potentially harmful interference we have tried to limit the SQRX to L band 
while connected to the BBS. I think that covers it, LOL.

QRP on the second channel is certainly possible, given that sometimes we'll 
have to switch to digital to collect telemetry.

Thanks for the interest.
