Peter,

I was a little better off: I probably decoded 30% in the first pass, but
I've been talking to N4HY about the P4 stuff for a year or more. We need to
encourage him to make a pass through the OU area (he's at VaTech now) and
spend an evening presenting to a club meeting... and maybe open said club
meeting up to other area clube (Rm 1350?)...

P4 has some interesting partnerships.

Also, there's an ESA/AMSAT-Eu DVS-B2 platform at least theoretically
situated on ISS. I've not seen any indications it's ever been fired up,
though.

“Big whorls have little whorls,
That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
Lewis Fry Richardson (1881-1953)
