You will receive the beacon on SSB.  You may recall the telemetry used on
satellites such as AO-10, AO-13, and AO-40.  This is just an enhancement.

The only time you will be transmitting to ARISSat-1 is when the transponder
is active.  It is a linear transponder, so the usual rules apply.

Subject: [sarex] ARISSat-1 Demodulation

Hello to the group:

Have been reading about the satellite and BPSK 1000,but then have a little
doubt on two subjects:

1- The BPSK 1000 part, can be decoded on FM, SSB or a combination of both?

2- In the same line, if one TX to it on U/V, what is the mode to use?
70cmUSB/2mLSB, 70cmLSB/2mUSB and/or 70SSB/2mFM?

Thanks in advance.
