Let’s face it, on a satellite pass all operators should show discipline and able to receive the down link perfectly. Transmissions must be kept to the minimum passing only relevant traffic.
This afternoon was one of those disciplined nets and the throughput was excellent.
As AO-91 flies in range of Kinshasa / Brazzaville in north Africa it encounters a signal which keeps the satellite active and blocks out all possibility of good communications.
Andre, ZS2BK determined the QRM area by monitoring the footprints of numerous passes. Not much that can be done about it though which is a pity.
But, before the satellite comes in contact with the QRM the tiny cubesat is perfectly usable for fast communications!
