LUSAT-OSCAR 19 CW-Beacon-Reception
LUSAT-OSCAR 19 or LO-19 can often be heard on 437.126 MHz in CW with Morse-encoded Telemetry (voltages, temperatures etc. from inside the spacecraft).
Sample: E LUSAT HI HI 6O AVT ABA AU4 AD4 AA4 ABT TTU AEE
The number after HI shows the used EPROM-block of the CW-microcontroller, O stands for OK = RAM of microcontroller isn't corrupted by radiation. The following eight analog values are in reduced Morsecode (A = 1; U = 2, V = 3, 4 = 4, E = 5, 6 = 6, B = 7, D = 8, N = 9, T = 0). The real values of each channel (X) must be calculated with the following formulas:
