I’ve been playing around with WSPR over the last few evenings with my new Yaesu FT-817ND.  WSPR stands for Weak Signal Propagation Reporter.  You basically send low power signals out over HF and some software on another persons computer picks these signals up and decodes them so you can see how far your signals getting. I’ve finally made my first trans-Atlantic contact.  Station W3HH in Florida could hear my transmissions at 5W from the UK.

It took me quite a bit of reading to get WSPR setup correctly, so I thought I’d write a blog post on how to do it in the future.  Some of the options and settings you need to choose for both the software on the computer and the radio were difficult to work out.
