During normal modes of operation, CAPE-1 will transmit a CW telemetry
beacon once a minute with a 9600 baud transmission, also once a minute
but interleaved with the CW. So, CAPE-1 will transmit a CW beacon and
then 30 seconds later transmit a series of 9600 baud AX.25 packets.
During low power modes the satellite will first drop out high speed
packets (CW only with a one minute spacing) and later start spacing out
the CW beacon. As per http://ulcape.org/wiki/CAPE1_Telemetry it will
take three CW beacons or one high speed transmission to get a complete
health "snapshot" of the satellite and we will appreciate anyone copying CW.
