In the KITSAT days, I used an IC-751 as the receive IF. It has a true

Not wishing to bring up bad memories, but two questions:
Did anything other than the plug incident happen? (In other words, did

Not a backup for phase 3d but a satelite with simular spaceframe and

Dear friends, FM transponder is OFF, it's mission is completed, thank you
for all the good responses. Based on this there will be more projects in
the future making benefit for HAM people of the World.
Currently only telemetry packets are to transmit data every 15 seconds.
