Just wondering if anyone has measured the frequency of the SO-50 downlink at the bird recently? I've noted it appears to be a bit lower than I would expect, about 436.793.5. The frequency wobble I saw over the pass was due to my step size in the Doppler correction. Obviously well within the capture range for 435.795 FM, but mostly curious. 73, Bob, WB4SON

Looks like your observation is spot on. SatNogs is tracking it at 436.793 - and it actually looks like (from the waterfall), that that half kHz may be there, too.
