Ok, what are they up to at HAARP (the High Frequency Auroral Research Program in Gakona, Alaska)? Are they really going to do it? Some recent posts by HAARP Chief Scientist Chris Fallen KL3WX on Twitter (see below) suggest that they're really going to do some tests in WSPR mode during the summer research campaign coming up soon!
I like the thought of maybe being one of the initiators of these HAARP WSPR tests; I suggested using WSPR mode to Chris Fallen in a Twitter post long time ago, and I also suggested it in my blog post / open letter to Chris Fallen here.
I'm really excited about this news, and I'm really looking forward to catching some WSPR signals from HAARP soon.
During the last research campaign, in the spring of 2018, I was quite successful at receiving and identifying one of the HAARP transmissions. The observed odd off time of one of their transmissions on 9.500 MHz helped me identify with 100 percent certainty the received signal as coming from HAARP.

| HAARP signal as received by PA7MDJ on 9.500 MHz on April 8th, 2018 made visible in Spectran and Argo which clearly shows the off time of 01:29:30 UTC, exactly as announced by Chris Fallen on Twitter (see below). This positively identifies the signal as coming from HAARP. Click to enlarge. |
During one of their earlier campaigns I was already successful at receiving HAARP on 9.500 MHz, but then the observed off time of exactly at the hour left some room for doubt (although not much, see my blog post here).
The received HAARP signals consisted of a carrier only, and there was no other way to identify the signals than by observing the start / off times of the received signal and to see if they correspond to the announced start / off times. The HAARP WSPR signals without doubt will be a lot easier to identify.
