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?
