A Report by Graham Collins, VE3GTC
The following is a report about the
analysis of the data gathered from the
onboard WSPR beacon – an Amateur
Radio experimental propagation
transmitter (EPT) – onboard the Polar
Prince for the duration of its journey.
The EPT was one of Hans Summer’s
(G0UPL) QRP‑LABS U3S kits. Jeff Milne,
VE3EFF, was brought onto the team and
employed a computer running Hans’ near
real‑time tracking software used to update
the QRP‑LABS website. I contacted Barry
and Jeff about my interest in the
endeavour and offered to collect CG3EXP
data, plot the ship’s position and provide
an analysis of the data during and at the
end of the voyage.
One of the compelling arguments used to
justify the installation of the EPT for the
