One of the XW-2 birds seems to have a steady digitial signal in the center
of the passband.  Is this from the bird, or something it is hearing on the

If it is on the 435.21 to 435.23 uplink it should be nice challenge to try
to derive its position from Doppler observations, and then start searching
on the ground.  Both are lots of fun and a nice ham challenge.

Again, I have not listend to these birds enough to get the big picture, so
if I am confused, ignore me.

Its just that this week is our classes annual week to tune in some
satellites and I have heard this signal multiple passes.
