Hi David,

 

Yes we can rule out antenna squint because the second pass this morning
(2217 UT)  was  very strong horizon to horizon.  Nothing heard on the
previous pass and VK's report nothing on the next pass so something seems to
be turning Delphi off before it gets down this way.  Unfortunately all
ascending node passes  (Today 9:45pm local and 11:22pm local) are all well
into eclipse so we only see a couple of descending node passes in the
mornings here.  Having only heard the one pass it seemed to be in what the
control team described as "emergency mode".  I had good sync lock but no
packets and it certainly sounded much different from the Demo file which
decodes perfectly.

I guess we just keep monitoring and waiting down under!

Hi Alan.

I think you're right.  Even the teams own news pages say that they have
trouble in the morning asending passes, while the evening passes here in
Europe are all fine.

Possibly a squint problem, but my feeling is that it could be the software
latching up after half a pass or so.  
I note that the evening passes here are all just after exiting eclipse and
hence the satellite is 'reset'

What are the ascending passes like with you?

Thanks

David

 

Once again nothing heard from Delphi over NZ on the 2041UT  36deg fully
sunlit pass.  Good signals from SEEDS, CUTE1.7 and even chirpy COMPASS.
 
I note that stations reporting no signal today are all reporting on
descending node passes while good signal reports are once again reporting on
ascending node passes.
 
Unless Delphi is turning off Southbound best guess would be an antenna
squint effect.  Are any stations reporting reception on Southbound passes?
