[Spooks] Pulses on 14066 and 14296 kHz

Mon, 9 Dec 2002 22:19:00 +0100

Hi Martin and all,

I'm probably off-topic, but I can see that your locator is near ottawa and
recently  I receive an article ( Actually I don't read it) about the systeme
H.A.A.R.P (hight frequency active auroral research project).This project use
36 antenna, locator is in Alaska (62deg23.5'N 145deg8.8'W)
Sounds could be provide from it???I don't know.
Look at HAARP for your personal information.

Hello All,

This is a little off-topic, but I wonder if others are hearing the
pulses (sounds like an ionosonde or OTHR) on 14066 kHz during local
mornings in eastern North America (but never later than 1530 UT).  It
isn't active every day and signal strength is a modest QSA2-3 here.
No evidence of antenna rotation or beam switching.

PRF is almost 25 pulses/sec and seems to vary slightly from day to
day.  I have measured the pulse period at several values between 40.44
and 40.53 millisec.

Bandwidth is rather narrow and the signal covers 14062-14070 kHz and
the pulse train in the lower half of the bandwidth has a different
epoch than those in the upper half, as if two pulses were being
emitted on slightly different freqs.  (Is this a technique to increase
range resolution without increasing bandwidth?)

DF from Ottawa, Canada, is SSE to S, or roughly along a line down the
U.S. eastern seaboard, across the Caribbean, and into central South
America.

On some afternoons I have heard the same signal on 14296 kHz, same
characteristics.
