Hi drew,

I notice that when AO-51 comes over ZL/VK after coming out of eclipse (about
5 minutes since eclipse) that after some use the transponder drops out and
will not retrigger for 10 to 15 seconds.  This behavior continues right
through to LOS.  I presume this is caused by the batteries still being only
lightly re-charged and with use they drop below some cut-off level.  My
question is to whether this is of concern and should usage in this part of
the world be restricted for longer after eclipse.

Back on now thanks to the heads up from John, and our West Coast command 
station, WA6FWF. Nothing to worry about on the satellite, it was a 
result of me trying to adjust the power on the previous pass.
