I can vouch for PSAT and SSTV with PSK however like Bob says it is very hard from the more Northern latitudes. N8URE and I did an experiment last year. I was able to receive waterfall text and some BW SSTV from Maryland and received in Florida. It took many weeks of troubleshooting however.
The only downside is that its orbit is at a 28 degree latitude and so is
low on the southern horizon for northern states. Though the elevation
goes up and down over a two week period by several degrees.
Let me know that it is working. Oh, also, the pass has to be in the sun
for power and for live images.

I didn't realize that it constantly transmitted what was in it's memory (at least I'm guessing that). I'm going to try that ASAP and let my club know too.
