Title: HAARP to Transmit Amplitude-Modulated Carrier Waves
Post by: Pete, WA2CWA on February 18, 2017, 01:16:44 PM
From the ARRL web site dated 2/14/17:

"The High Frequency Active Auroral Research Program (HAARP) in Gakona, Alaska, will soon undertake its first scientific research campaigns since the facility was taken over by the University of Alaska Fairbanks (UAF) Geophysical Institute 18 months ago...HAARP transmissions will take place within the facility’s transmitter tuning range of 2.7 to 10 MHz and should be audible outside of Alaska and may even produce visible effects within the state...

...Fallen told ARRL, “I plan to start and stop each experiment block with an audio Luxembourg-style broadcast — transmitting two amplitude-modulated carrier waves at different frequencies separated by about 1 MHz, with the resulting skywave signal being a mix of both frequencies.”...experiments will be carried out February 19-22..."

At the urgent request of the FCC, Tim WA1HLR is being flown on a special USAF stealth aircraft to Gakona where he will be parachuted to the site to de-hyellify the transmitter.

From the Operations Page of HAARP.
Luxemborg transmissions at 2.7 and 3.3 Mhz  simutaneously at 1930 AK standard time on 19 20 and 22 FEB
Airglow transmissions at 2030 AK standard time on 21 Feb 2.7 Mhz

Will my old foil hat work, or do I need to make a new one?

Did anyone listen?

I heard a strapping signal on 2.7mhz...s9+10 in Maine, sounding similar to a digital voice transmission, nothing on 3.3, and nothing on the plus and minus images except obvious other licensees.  As strong as the 2.7 mhz signal was in Maine, I suspect it was something other than the haarp.  If I remember, I'll listen on other nights.

Has anyone found out just how many xmitter HAARP  has now?

Last year,  they where decommissioning them like crazy I heard.

Lots of 4x10s,  for sure!

Over 400 4x10's.. Not all the transmitters are on the air yet.. they are operateing at around 60%.. only the tubes where pulled.. no transmitters where distroied.

There never was any destruction, the only decommisioning was to pull and store the tubes.

The complete plant can go back online at any time, with minimal effort.

This set of science ops required only a certain amount of power.

Even played music - in stereo. Pretty cool.

Do they take requests?
