HF Mystery Signals / Re: Unusual Signals

An audio, or preferably a iq recording might generate some clues. My guess is its very powerful and widebanded and thus a state actor, if not a local qrm source.

Many parts of the world do not recognise HFGCS ownership of 11175. In fact, when Billy Jeff "Busypants" Clinton was president and Kosovo was a thing, the Serbs actually jammed triple one with usb voice in scathing diatribe about the USAF, NATO, President Busypants, and all else, good times.

Equipment / Sometimes a blob is better.
« on: May 04, 2022, 2044 UTC »
A HAM friend and I were discussing antennae of various bands and configurations one day. He mentioned once having a 600ft dipole up for a while, the center insulator up about 75ft on the tower. The ends were secured to some fencing used to pen the cattle. I was awestruck by this wonderous dipole revelation and asked how it performed, expecting legendary dx from such a monstrosity.

Nope.

He ran it on all the lower bands and it worked ok but not much better than the dipoles had had curt for each band, and expected it to be the cats meow on 10m as that was the band he had no antenna cut for. He heard no one on 10m and apparently no one heard him despite hours of calling. He wondered wtf was going on as he had multiple wavelengths of dipole out there to get massive gain on 10m but nope, nada, zilch.
So he finally ran a antennae sim and saw wtf was going on.
No one was going to hear him (nor he them) unless the receiving station was directly in line with the legs of that fabulous dipole. if he had simply moved the legs so it beamed, for example, into JA land he might have the killer signal in Tokyo. Did I mention when the wind blew, or even worse a storm was imminent, you could arc weld with the socket at the end of that titanic dipole's coax? When he saw that he decided it was a bit too dangerous of an antenna to let live.

Then as he was still speaking I recalled the simple 2wl wire I ran on 11m, up about a wavelength. A guy across town had me s9 plus on that antennae while a guy two blocks from him never heard me and wondered who he was talking to - yet I could hear them both fb, several others in town couldn't hear me either. All could hear me when I went vertical.
I modeled a 2wl wire on 10m and noted the many and deep nulls, explaining the reception oddity noted, and here I thought my breath just smelled bad.

So.... sometimes an undefined blob of rf (here meaning a halfwave dipole or wire) is better than rf pattern with steep jaggy edges, depending on what one wants to do with it of course.

:D

Huh? / Re: Why is there so little interest in MW pirates?
« on: May 04, 2022, 2004 UTC »
A friend in Iowa who had a 6 watt ambc pirate sta (think this was a phono setup like in ye olden dayes) when he was a wee pirate. He and a friend ran some wire along the tops of trees for a few hundred yards in a wooded lot behind his house, they were heard in Canada. Never underestimate a kid dumb enough to climb several tall trees with a spool of wire, he's now an engineer at a tv sta. Hi John if you read this.

HF Mystery Signals / Re: Amateur mode 3596 kHz - FSK?
« on: May 04, 2022, 1937 UTC »
I show a few CIS fsk modes with a 2kc shift;
CIS_98.8_2000, 98.8 baud
CIS_100_2000, 100 baud, listed as REA4 Russian AF HQ Moscow
Both listed shifts might be the same modem running different encryption and/or framing, dunno.

Next closest shift in wcode hf table;
BAUDOT F7B, 1550 shift, 250 baud, listed as UKR (Ukraine) FSK encrypted via T207 modem

As an addendum, S4285 is coded to tolerate a number of interfering carriers. I presume this carrier is not organic to the S4285 signal in question.

If it's local it may be a street light starter going bonkers, they can emit horrendous rf hash in that condition.

Very nice production!

Hi, did you catch this via remote sdr or your local rigs? Reason being is the time of day and freq might be indicative more of Pacific region air force assets rather than those deployed to Ukraine. You may also be receiving this sig via longpath if it is from the Ukraine area, that seems more likely to me if these are Ukraine assets. Russia has sent long range aviation (as they like to call their strategic bombers) off the coast of Japan.

I wonder if this is the fsk system I read about where they studied propagation betwixt US and UK, also US and JA, and JA and UK. Have to dig up that study and flesh things out.

Remember the WARC bands are contest free, so try those when the HAM bands are infested.
