Got the urge to try out WSPR. Installing WsprryPi on a Raspberry Pi I had laying around.
Didn't work because my version of gcc was too old (didn't recognize one of the flags). So went to upgrade gcc
(Truth be told I probably should have just upgraded to a newer version of Rasbian full stop, but this was something I could easily do in the background while I was doing some other things.)
Much happier after that.
