Telecommand transmission

[VK2FAK]

Hi All..


How do you go about sending command signals to a LEO satellite.  using 9k6 ax.25 gfsk  .

What radio is required, and software to do the job......?

Never done it here,  and at this stage don't have a radio that would do  9k6 baud.


The reason I ask, the problem came up again yesterday with a LEO satellite, which needed a reset, it fixed itself as far as I know, But that's about 3 times now, so may be an idea to set-up for it...

Thanks for those, I have most of the decoders needed for current sats, just not sure on the TX side of things. As the last sat issue it was required to upload a few HEX codes and the destination callsign
