The Airforce Academy turned over its Falconsat satelliite to Hams and I
had not realized it supports APRS digipeating.  But at 9600 baud and cross

This is a great bird to get some experience on operating 9600 baud.

435.103 MHz down and 145.840 up DIGI call of PFS3-1.  While of course
setting 5 memories to chase the Doppler the full 20 KHz during the pass.

I guess we need some APRS IGates to collect packets on the downlink.  Of
course this is not easy because the doppler shifts through 5 channels at 5
KHz steps due to DOppler.  But if we have enough passive receivers all over
the USA  Then one of them will always be in the passband for at least some

Just tune in 435.110 which is 7 KHz high and you will at least hear the
start of the pass and if you are in the shack, you can then follow it down.
