Hello Sat-Friends,
today I was able to receive morse telemetry data from the cubesats CUTE-1 and XI-IV.
I loaded down the telemetry decoder from their respective sites.
Theses birds are transmitting pictures from a built in camera, but
only via Japan, because of the power budget.
73, Karl
Here are the results of the telemetry reception:
