ARLA/CLUSTER: HAARP solicita reportagens das suas emissões ao radioamadores a nível mundial

[João Costa > CT1FBF]

O que é o Projeto HAARP.?

O projeto HAARP - High Frequency Active Auroral Research Program  (em
português: Programa de Investigação de Aurora Ativa em Alta Frequência) é
uma investigação financiada pela Força Aérea dos Estados Unidos, a Marinha
e a Universidade do Alasca com o propósito oficial de "entender, simular e
controlar os processos ionosféricos que poderiam mudar o funcionamento das
comunicações e sistemas de vigilância". Iniciou-se em 1993 com uma série de
experimentos durante vinte anos. É similar a numerosos "aquecedores"
ionosféricos existentes em todo mundo, e tem um grande número de
instrumentos de diagnóstico com o objetivo de aperfeiçoar o conhecimento
científico da dinâmica ionosférica.

HAARP request reports from radio hams

Alaskan HAARP experiments: radio amateurs and SWLs asked to record the
events they hear and post reports to social media

The ARRL writes:

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.

Among the investigators is UAF Researcher Chris Fallen, KL3WX, who will be
working under a National Science Foundation grant, “RAPID: Spatiotemporal
Evolution of Radio-Induced Aurora.� Fallen says the 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.

“This time my experiments will largely focus on artificial radio-induced
airglow that potentially can be photographed from nearly anywhere in Alaska
— weather permitting,� 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.�

Fallen said that he has prior success reproducing the “Luxembourg effect�
using two DTMF tones. “But this time, I have a short simple musical
composition recorded by a local musician,� he said. “It was composed
specifically to take advantage of the Luxembourg effect.�

Just which HF frequencies Fallen will use won’t be determined until shortly
before he begins his research. “The specific frequency chosen during a
particular experiment depends on the experiment’s objectives, FCC
regulations, and ionospheric conditions at the time,� Fallen explained. He
will use ionosonde data to guide frequency selection.

Fallen said experiment times and frequencies for his airglow and Luxembourg
experiments will be updated on his blog and on his Twitter account linked
in the blog. He encourages radio amateurs and SWLs to record the events
they hear and post reports to social media or e-mail him.
