If you don't yet have PSK31, but want to get some data, team up with an HF friend in your area and ask him to just transmit for the next 10 minutes and you can then receie his downlink while commenting on his signal strength throughout the pass.
At this moment in the year HF propagation on 10 meters is almost non-existant in Europe (from time to time http://dxheat.com/dxc/ suggests there is good propagation in the americas). This means the PSK31 uplink band for PSAT is usually quiet.
A good time for testing this. I can do uplink on HF or downlink on 70cm, but not both during the same pass. My locator JO22NC and my time is limited due to work/family life ;). HF uplink is easier since that's all set up in the shack.
