Shhhh… I’m WSPRing

Shhhh… I’m WSPRing

When I’m waiting for my KX3 to get fixed under warranty at Elecraft (the’ve had it 10 days so far, but I’m not bitter), I acquired a K2 and a very good price. I mentioned it on my last entry. I’ve found out it is an older one and I’m going to send it to Don Wilhelm once I get my KX3 back. He updates K2s to the latest and greatest at a fraction of the price of Elecraft. It will be equivalent to the current K2s once he is done. He’ll also be able to fix the low output on 20 meters I found I have.

Meanwhile, I’ve been playing a lot with the digital modes. The new FT8 is really cool and fast. I like it a lot better then JT65. It only takes 1:15 – 1:30 to complete the average exchange as opposed to 5 minutes with JT65. It also has a neat feature called auto sequence that will actually complete the QSO for you instead of you just sitting there watching paint dry waiting the minute for each exchange (15 seconds in the case of FT8). You really seem to need it in FT8 because the exchanges go so fast.

The mode I”ve really been playing with is WSPR. That stands for Weak Signal Propagation Reporting. It basically beacons out a signal at low power for 2 minutes, then listens for 6 minutes in 2 minute increments for signals. You then go the the WSPR website and can look and see who has heard your signal and whose you have heard plotting nicely on a map. What you see above is where my signal has been heard this morning on 40 meters. All throughout the USA and all the way to Australia!

What WSPR is really good for is seeing how band conditions are and how your antennas are working. I currently have 2 antennas – a fan dipole up 30 feet in an inverted V and a Cushcraft R9 Vertical. I can compare where the two antennas have been heard using WSPR to see which is the best to reach a particular area.

Why don’t you give FT8 and WSPR a try, I think you will like them.
