"Successful" HAARP WSPR test?

Well, not in my book.

Southgate News carries news of this test using WSPR around the end of July and start of August. The report mentions the hundreds of WSPR reports from all over the USA and Canada. Using 1GW ERP this is distinctly average.

OK, apparently D-layer absorption was high on 80m, but I would have expected reports from elsewhere too.

Latest HAARP WSPR test tweets

The HAARP team in Alaska tweeted this an hour ago:

HAARP WSPR plan for 31 July 2018 UTC
2340: WSPR vert 02 var gain const power 80m 3.5926 MHz
2348: WSPR vert 01 var gain var power 80m 3.5926 MHz
2356: WSPR vert 02 var gain const power 80m 3.5926 MHz
0004+: WSPR vert 01 var gain var power 40m 7.0386 MHz
0010+: END OF EXPERIMENT

HAARP 80m WSPR test

A reminder that WI2XFX, in Alaska, will be on the air tonight on 3.5926 USB dial (2300z for about 30 minutes) with a huge ERP on WSPR using the HAARP antennas. See the ARRL site for more details. I may try looking for it using my earth electrode "antenna" in the ground.

Now QRT

On both 6m and 10m I have now gone QRT and disconnected everything. I noticed a CT calling "CQ NA" , although I am not sure if he was copying stations from "across the pond" on 6m FT8.

Tomorrow I may try 10m FT8, although I want to see if I can see the 80m WSPR test from the HAARP station in Alaska in the late evening UK time.

80m WSPR using HAARP antennas and 80kW

Southgate News has a piece about 80m WSPR tests using the massive HAARP antennas and huge powers up in Alaska. This may well be worth looking for.

At one time this was a US government facility, I believe, and the centre of all sorts of conspiracy theories!

HAARP news

There are some interesting experiments going on.

HAARP - stay of execution?

It looks like the HAARP (supposedly auroral research) facility in Alaska may remain until May 2015 although non critical (movable) kit is already being moved out. It remains to be seen what happens after next year. HAARP is also known for its generation of ELF radio signals as a result of ionospheric heating. The peak power of the facility on HF was massive.

HAARP to be saved?

The (controversial) HAARP project in Alaska is closing and the facility being dismantled, but scientists are trying to save it. See http://www.adn.com/2014/06/03/3500302/scientists-make-last-ditch-effort.html?sp=/99/100/&ihp=1 .   There have been all sorts of conspiracy theories. One of the objectives was to generate uW or mW level ELF signals (to communicate with submerged nuclear submarines) by heating the ionosphere with AM modulated HF signals.

"What a shame if they have to tear it down, they just finished the build out to the full array a couple of years ago!
I was fortunate to get a tour of the site about 10 years ago as my friend Steve W4YHD was the Chief Engineer, quite impressive! I have some photos (35mm film, not digital) which I need to scan.  The HAARP transmitters were true AM transmitters as they were used to heat the ionosphere and generate e.l.f. waves by modulating the carrier with low frequency audio tones, very inefficient (but all elf transmission schemes suffer from lack of efficiency),many megawatts of HF energy used to excite milliwatts (or perhaps microwatts?) of elf radiation from the ionosphere.


    I recall that they had a Radar on site and were supposed to shut down in case an aircraft flew through the beam. They also had an ICOM R72 receiver so they could listen before transmitting so as not to cause QRM !  The whole lashup was powered by a series of 5 generators driven by diesel locomotive engines.   The transmitter was actually a bunch of final amplifiers, solid state driver and a 3cx5000 PA tube, housed in trailers below the antenna array, each trailer housed a number of 3cx5000 PA's - the PA's were fed by an HP synthesizer (don't recall the model #, might be in one of my photos) and fed with equal lengths of coax so all PA's would be in phase. There was a method to shift the phase across the array so as to change the shape and direction of the beam. The antennas were bow-tie dipoles broadband from 3-10MHz.  The whole thing was controlled by Sun Sparc workstations from a master control room.  Just for fun I tuned up one of the transmitters on 7.290 MHz AM to see if I could strap Ashtabula Bill W8VYZ, of course it was daytime and I don't think anybody was affected!

   Was hoping to make a return trip to see the fully built out site but its looking very questionable at the moment.
