[amsat-bb] AO-91: *No* uplink frequency changes needed for Doppler shift

[Bob]

What if we consider it from a different perspective...  Say two signals of
approximately identical strength are transmitting to AO-91.  One has
adjusted for Doppler so the signal is showing up at the center of the bird
passband all during the pass.  The other has not, as is about 8 KHz on the
high side when the bird is approaching.

Wouldn't the signal closer to the center of the RX passband be the one more
likely captured?

Therefore wouldn't there be an advantage to adjusting for Doppler?
