G'day Guys,

While listening to the 40m hams trying to catch VA7MLW Canadian sailing
solo run the world, the band is total washed out with this spectrum
noise. I have a recording of this BLOODY annoying spectrum noise,
which I'm sure is OVER HORIZON RADAR or something very similar, can
anyone else please confirm this ?

Recording - http://ustream.tv/recorded/K86S2mXnhNYZzaOknbgAMg


Sounds like a digital transmission mode like AMTOR. If it is it should
be two tones. If you were in the right sideband mode and tuned to the
right frequency it would sound like a digital mode to you. If this
signal is heard throughout the band then made you are close and your
radio is overloaded.

Nope.

Maybe digital but guaranteed NOT to be AMTOR, PACTOR OR G-TOR. These are
"linked" modes, with a pause between transmissions to wait for the ACK
or NAK from the other station. All of the TOR modes sounds sort of like
a cricket -- nothing at all like the signal in question sounds.

Thanks Billy,

I was about to say that I'm fairly well versed in my digital modes and
tools for decoding them and this is not a standard digital mode that I'm
used to. I've heard it before on the bands, but usually not on a
frequency range that annoys me.

Also, I'm using a ICOM R75 and she does not ghost like a the cheat
receivers. Noooo way this is something else, and I also Heard the same
noise across the same Frequency range on DEGEN 1103 and its wire
antenna. So this is differently Broadband spectrum wash / noise.

Anyone else heard this noise before and willing to put forth a
creditable suggestion ?

Cheers
Mark

Michael,

No worries heres an MP3: http://www.mediafire.com/?5dcdndzhh1t

For your own and others info, there are many free online media converts,
one I like using is http://www.mediaconverter.org/ This site allow you
to point to a URL or upload a file and then convert it to another media.

But hopefully this will work for you :)

Cheers
Mark

Much appreciated, I have it as a flv he
Recording - http://ustream.tv/recorded/K86S2mXnhNYZzaOknbgAMg

Its a video and sound of me doing a band scan from 7100khz down to
6500 khz.


Sorry, no go (I cannot upgrade to F.P. 9) and trying to save the flv
using the embedded url:


http://flash7.ustream.tv:18881/broad...&brand=ustream


is refused with the odd message: "NEM NYERT!!"

I imagine others would like to hear it as well as a simple audio stream or
from a downloadable file.

Regards,

Michael

Thanks. I've posted the file on my site to permit downloading and
saving without needing a ripper:

I presume that only the approx. 10 Hz pulses constitute the signal
under discussion and that all other sounds are QRM.

Has anyone heard HAARP or other atmospheric research RF emissions
for comparison? The P.R.R. of this signal suggests to me some sort
of power transmission (RF pumping of the ionosphere?) or industrial
process rather than conveying intelligence. Or could it be pulse
doppler? Wouldn't O.T.H. radar be using a chirp and a much lower
P.R.R.?

Regards,

Michael

The broadcast mode (FECTOR?) is a constant 100 bps narrowband FSK.
Sounds pretty much like any other RTTY.

Yeah like you know anything bozo. There are AMTOR modes that are raw
that sound just like what I heard. You have to be a fricking moron to
tell me what I heard on the radio. You qualify.

Thanks Michael,

Yep just interested in the BUZZ / pulses, the other background noises
were from other sources / frequencies as I scanned from 7100khz down to
6500khz so show how much spectrum was being affected.

I got confirmation from two blokes on the amateur radio forums. Most
like originating from china :) So who needs the Russian Woodpecker when
China fills bands :)

I was also provided a link to http://www.iarums-r1.org/ the website of
the Region 1 Intruder Watch. Look like a very intereting site.

Cheers

Well, yeah, like I would. I've made a couple of hundred of
AMTOR/PACTOR/G-TOR contacts over the years. How many have YOU made, huh?

There are AMTOR modes that are raw that sound just like what I heard.

What do you mean by "raw" AMTOR? Is that your very own 'technical' term?
You would have us believe you are a genius. If so, be specific. Do you
mean FEC mode (Mode B)? or ARQ mode (Mode A)? NONE of the literature
refers to "raw". In any case, *neither* variant of AMTOR sounds anything
at all like the recording that the OP made and posted.

Furthermore, at least for the sake of this discussion, -TOR signals
nominally use 1 kHz of bandwidth or less. IF you listened to the OP's
recording while watching him scan the band and IF you noticed the title
of his post ( Broad Spectrum Noise / Buzz 6500 kHz - 7100 kHz),
hopefully you would realize that an AMTOR signal, raw, cooked or
otherwise, would not be 600 kHz wide.

You have to be a fricking moron to tell me what I heard on the radio.

Sorry, YOU have no clue. Me (nor anyone else) was telling you what you
heard on -your- RADIO. *I* was referring to the RECORDING made by the
OP. Then, we are -all- listening to the -same- thing. Get it now?

In regards to your obnoxiousness, rudeness, vulgarity and name calling
above in response to my germane and on-topic post, I can only hope you
get along better in real life than you do in this newsgroup. In my
humble opinion, you seem to be exhibiting some characteristics of
Narcissistic Personality Disorder, megalomania or both. You seems to
perpetually want to be controlling, in charge, with an ego as big as
Rhode Island. If you are going to ridicule the intelligence
of others, you better be sure that -you- are above reproach (just having
a stupendous ego doesn't count). "Raw" AMTOR, indeed.
The only things raw here are your vulgarity and half-baked, so-called
'knowledge'.
