Ship Ahoy! CG3EXP on WSPR

Have you heard of the CG3EXP voyage around the north west passage of Canada?

Sadly, I hadn't heard a thing about it until yesterday.  As soon as I started listening, the WSPR beacon at 200mW popped up on my screen at a good signal strength, despite being a mere 200mW from a pretty tough area of the world.

Details of the voyage can be found here.

The transmitter is a QRP labs US3 unit, transmitting on the 40, 30 and 20m bands.  Interestingly, transmissions are showing a couple Hz of drift, which is not something one sees with the comparable WSPRlite units.

So far, I've had a handful of good spots of the ship, which is no mean feat because only about 10 stations at most over several hours have also heard the beacon.
