Aug 2nd, 2009, low elevation pass still decoded
New experience:
My last pass of today for ANDE-2 had only 8 degrees max. elevation. And - my station did still decode 2 packets from Pollux !
During the day, with the higher elevation passes, RF link was not alway much better (read, I just get normally a few more packets)
This is the same as yesterday and same as with the ANDE-1 mission; low elevation passes sometimes give very good quality RF links.

Keplerset looks OK, as start/stop times of hearing the sats match the predicted passes. I can hear Pollux from/till 1 degree elevation. (hear is not the same as decode :-))

I missed the last pass due family activities... But here are the two passes from this afternoon.

Hi Mike...
I notice that the packets you receive seem all perfect...have you considered turning your "PASSALL" ON and leaving your "buffer" ON to be able to look at everything coming down?
Just a thought...
