[amsat-bb] Has anyone heard the Exceed Satellite?

Unfortunately, when Fox-1Cliff  (and all the Foxes) turns on its Tx it
starts at a low frequency and sweeps up to its nominal 145920 over the
course of a second or less.  You might have heard it sweep across 900.
There would be no modulation while that was happening, and it would happen
about every two minutes.
