There are two HF satellites currently operational if you want to play HF!
That is, the 10 meter uiplinks on PSAT and PSAT2. THey are both linear uplink transponders with an FM downlink. They were designed for PSK31 uplink, but PSAT2 has also been opened up for SSTV uplink as well.
There is no reason it cannot do SSB VOICE as well. Just TX on 29.481 SSB and hear yourself on 435.350 FM downlink. Of course, there needs to be someone on PSK31 at the same time to trigger the transponder. Can someone talk over their own PSK31 transmit?
ANyone want to try it and let us know? The transponder on PSAT can do the same thing, but the uplink is in the CW portion of the 10m band and would violate the band plans.

Our HFSat is flight ready and I am requesting my organization to let me publish the entire transponder details. This is a linear transponder with 21 Mhz uplink and 29 Mhz downlink.
I'm extremely pleased to hear this! It's been a long time since we had
an entirely-HF LT satellite.
For those who don't like homebrewing equipment at VHF/UHF, this offers a
great opportunity to roll your own satellite rig (or use a pair of uBITs, right?).
