[Lowfer] LF ham bands

[Douglas Williams]

Over the weekend, I logged a plethora of WSPR receptions on 630 meters
Saturday night, the longest of which was over 7k KM away (Hawaii). I
switched to 2200 meters WSPR for Sunday and Monday night and logged,
multiple times, two stations, WH2XND and K3RWR.

Tonight (actually starting right now), I am monitoring 474.2 KHz USB using
the new FST4W mode. Not sure what I can expect. I have it set to
automatically upload spots, but not sure where they wind up? WSPRnet
perhaps?
