I should have been a little more clear in my email earlier.  The
transponder on LilacSat-2 active today was not the normal FM one but
rather a SSB transponder.  It is experimental and has no AGC according
to the reports from Twitter.  I'd suggest paying attention to the
AMSAT OSCAR status page (http://www.amsat.org/status) and following
BG2BHC on Twitter for operational updates.

I was using manual control but you can add this line to your
DOPPLER.SQF.  It will need some minor calibration:

LILACSAT-2,437200.0,144362.0,USB,USB,NOR,0,0,SSB Transponder
