Digital Sat. status on Mar.1st



Digital Sat. status on Mar.1st:

   UO-11 ...2401.500MHz  1200bps USB : S Beacon
   UO-22 ... 435.120MHz  9600bps FSK : Operational
   AO-40 ...2401.323MHz   400bps PSK : S2 Beacon


I listened to UO-11 RS45 signals in 2401.5491MHz-2401.4470MHz
with AOS-LOS doppler.  UO-22 is as good as KO-25.
AO-40 was began to hear from 2401.3607MHz at MA251.
In the below AO-40 gif_file, you will see the "mirror" spectrum
of Manchester Code BPSK signals.
