Well that certainly makes it a little easier. Are the doppler issues any
different than the normal ones we face on a 70cm satellite?
The TLE on that Chinese sat suggests it'll get passes over the US, so
that's good news if it's actually another FM bird. Having a handful of new
satellites up there all at once will hopefully spread out the crowds so
that we don't have people blasting them with 50W trying to beat out the
other stations.
