It is very possible that the mode change on Feb 27 (to V/S) will be postponed. The satellite is still seeing periods of "eclipse" due to sun angle, etc. At this point we need full sun to operate in S-band, so the mode change is dependant upon telemetry showing that we are good to go.
Things might work out, but my hunch is that we'll have to postpone a day or two. Updates will be posted here as things play out. 73, Mark N8MH >> -----Original Message----- >> From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On >> Behalf Of Mark L.
