And it is loud and clear in EU too: 9+10dB
So an European Signal?

Greetings: I only have one radio to check those frequencies so
was wondering if the QRM is generated here or what..
A snapshot is at:

and the multiple tones seem to be 30Hz apart across the entire waterfall
300-2500Hz.. Below
On Friday October 31, 2008 I'm going to begin publishing my LF/MF/HF/6M
frequency radiowave propagation forecast once again. It will be located at

I have an archive of daily solar, space weather and geomagnetic data going
back through 2001. Year 2001 is at

That looks like the interference I had at one time from my monitor,
and in exactly the same place. If you can actually hear that noise on
the radio, try turning the computer monitor off. Does the noise stop? If
so, you may have to adjust the frequency of the monitor (if it is
adjustable).
The signal is back and is strong again today at 16:35z on Sunday.
It does sound like RTTY, but unable to copy any of it...
I have made a recording if anyone would like a copy.

Sounds just like the stuff that was on 40 meters
a few years that was coming from south America.
Think it was Brazil...
An FPGA is a good choice as they have advanced to the point where a 1 MHz wide
signal can be processed in a $10-20 device.
The number of points to use in the FFT is related to the multipath spread of
the received signal. HF signals with ionospheric propagation tyically have a
spread between 1
I am copying it some 20 dB out of the noise here in Havana at 21:55 UTC
on 14173 center.
It has 8 threads, plus some other two that show up on the side, at much
lower intensity, possibly IMD products, as their amplitude seems to
track the larger peaks excursions. The tones are 875, 900, 925,
Seems that just a very few listen to the ARQ modes now days.
Interesting Jose, I hope some ID's it soon, must have good finals in their
transmitter...it has been QRV all day!

wonder why the world the FCC would grant such an experimental
license. Among many other reasons for denying the experimental
license it is my understanding that it is a long-term goal was to
move broadcast stations away from the 40 m amateur band - at least
in areas including Europe and the

Very loud here today too
Might be coming from Europe. I was hearing an EI station stirring up a
pileup one kHz up.
The EI station was keeping this signal out of his USB passband, so I
assume it was a QRM source for him ... 8-)
So, this signal coming from beyond the skip zone in EI.
