I did some tests with PSK125R (125 bps BPSK + NASA r=1/2, k=7 convolutional FEC code) via the transponder and could copy my own signal very well. I am using FLdigi and 1.5W into an 1.2m offset dish. RX is an Octagon Optima OLSO without mods. The FLdigi AFC can track the LNBF LO drift quite well.
I will be calling CQ around 10489.625 GHz tonight and for the next few days after 22:00 UTC. Replies will be much appreciated.
