SatclockRS41

This was an experiment to see if a ~100mW RS41 could bounce off a linear AMSAT -- as a desperation recovery method. To be sensible and good-operator about it, it uses orbital prediction code I wrote >20 years ago to find when a Linear bird is overhead.

I was told off for even thinking it, but the guy who said that then went off to score Twitter upvotes by doing it himself :p .. A SatNOGS receiver in Queensland heard our attempts from Newcastle and Adelaide.

VK5QI mentioned the frequency bands for the modes used (CW, SSB, etc.) in the linears tends to be rather tight. If putting this back into action again, doppler calculations should adjust the tx frequency to keep things in-band.

Again, the original code came from the RS41HUP project. I provide no apologies for reformatting the source to GNU indentation standards, as I use Emacs.

Bulk of the RS41HUP and my prediction code is GPLv2. The STM stuff is non-Copyleft.
