We finally have stock of our WSPRlite system. WSPRlite is a small standalone WSPR transmitter that covers 20 thru 160 metres. When used with our analysis website http://www.DXplorer.net , WSPRlite provides a unique way to compare antenna systems in real-time. The basic facilities of http://www.Dxplorer.net are available for all WSPR users to experiment with.

The attached screenshot shows a series of nighttime spots between the UK and Denmark. I often see similar runs but to different Scandinavian locations. They are always very specific paths. My theory is that they are the result of E layer propagation from the northern wall of the mid latitude trough. This dips south in slightly disturbed conditions. Is that a likely explanation?

Hi folks

We have developed a way of testing antennas using WSPR. It consists of a special WSPR transmitter (WSPRlite) and a website (www.DXplorer.net).

The website is available for anyone to use - you don't need a WSPRlite. It works well on a phone, tablet or desktop. It's a neat and unique way of looking at WSPR data. If you have a beacon running on 160-20 m give it a try with your own callsign. www.DXplorer.net

I teach physics at a high school. Two WSPR projects come to mind for my students to develop:

1) A solar powered WSPR beacon to be deployed in a challenging environment in the Atacama desert. I have contacts on the ALMA project:


2) An ocean current monitoring beacon using "on the fly" position encoding to measure currents in the North Atlantic.

Any other ideas out there?
