I like to see the 10m uplink "arrow" approach :-)
While PSAT-1 is a nice "proof of concept for PSK-31" in reality it does nothing for the portable operator and that is what the original post is all about. Bad behaviour is not solved by switching to different satellites and different modes, it is solved by education, courtesy and the "gentle" reminder.
Using PSK31 is a great idea, the 10m uplink is the real issue for the non-use of PSAT-1. Should I say "fatal flaw"? Not many of us have a 10m dipole ready as part of our satellite setup (stationary or mobile for that matter). It is time that we move on and promote digital modes on frequencies that are actually used within the allocated satellite bands and even better on higher bands where we have allocations and we don't use them. How about a PSK-31 Cubesat within VHF/UHF? That is a nice mobile challenge combining portable TX ability with a tablet :-) and some new apps. Let's think outside of the box for a while... and leave 10m on the ground where it belongs LOL :-)
Food for thought,

I too have noticed some serious SAT-HOGs having a QSO, which prevented me from making an HT-ARROW portable OP contact.
Take a break from the congestion.... come to the wide open multi-user wideband transponder on PSAT-1. Downlink is good on a handheld arrow on 435.350 MHz FM. It should be able to support dozens of simultaneous full duplex QSO's in the PSK31 waterfall.
Just pick an empty spot and key your TX solid for the full 8 minutes of the pass on your 10 meter PSK31 uplink 28.121 MHz..
To run fullduplex, just run two copies of your favorite PSK31 software. One receiving the FM downlink and the other transmitting on the SSB uplink. Even better is to run Andy K0SM's TX-only uplink client that pre-adjusts for Doppler so everyone can decode you with no adjustments.
