CIS Navy on HF

There is this:

Is that what you were thinking about?

A posting on eham claimed that the Chinese CW decoder is based on this:

I have not verified whether that is true or not.

[Josh]

Yeah, thanks. There are some hardware decoders that are almost legendary for being able to handle poorly sent or fading code. Nice to have one but not going to spend $150 for a used one, a ten spot I won't miss for one that does the job well enough on good clean signals, plus with free shipping.

This link you provided;

has more or less what I want to do, put the thing in an altoids can with remoted controls, to keep rfi from getting int or out of the thing as well as protection.

Was considering hacking the front panel of a hf rx that had open space for the display and controls of the code reader, but that then limits its usefulness to that rig alone, even if that rig is pretty much devoted to cw rx.

[Josh]

i haven’t heard anything rither Josh, so I’ll be interested to know what you find.

Lol I was hoping you'd catch this post before 2200 and tune in!

Nada heard that day, a look out the window shows plenty of daylight left so really shouldn't expect to hear this, especially with a horizontal, a vertical might stand a chance. 10 minutes till showtime!

Heard some CW on 7422 at 2200 but there was too much splatter from the station on 7425 to decode anything that looked logical.

VVV RMP RMP RMP de RHO62 QSA? QTC K
RMP RMP RMP de RHO62 =SML= FOR RJH74 and into groups

RHO62 ADMIRAL VLADIMIRSKIY
RMP Baltic Fleet HQ

[JCMaxwell]

Finally some traffic.  Which frequency Josh?

[Josh]

Lol sorry, 12464 for this one. I keep one rig with decoder tuned overnite to whatever freq has the least rfi, in this case 12464. We need to branch out to the lower freqs, seems they're hiding down there.

2776
3356
3248.5
3500.5
3734
3762
3765 USB voice ship to ship
4635 apparently very active
6290
6346 RIT RADIOPROGNOZ 1000Z
6461.5 RMP duplex with 6494.5
8120 RAA Moscow simplex
11000 RIW simplex from hq to ships

 You'll note some of these are in the 80m HAM band, but around here the specific HAM freqs are often quiet, so a catch is possible.

thanks josh

Around 0900R (ROMEO or Eastern time) on 12464 a beacon started up. At first thought it was sending random letters every 30 secs, lasting for a few hours. I thought it was either poorly sent or poorly shaped cw as the letters had bad spacing but finally it started to come in strong enough to overcome the fading and multipath, it was a single long dash lasting almost 3 seconds.

[Josh]

Possible new call, RK9E calling RIW with QSA? and QTC, 1330Z 17FEB20

[JCMaxwell]

Thanks Josh

12464?

[R4002]

Do the Rooskies make a habit of using 80 meters in USB mode?  Seems like it’s pretty common for marine purposes (military and otherwise). 

I’ve read numerous reports from hams in Europe of Irish fishing fleets, Finnish trawlers, Italian fishermen in the Med, etc. using 3500-4000 kHz in USB mode for ship to ship comms.  It’s a good place to hide a military net.  Same with 40 meters.

The split frequency operation seems pretty common too. 

[Josh]

Thanks Josh

12464?

Another oops and yes, 464. I try for two consecutive 100 percent callsigns copied before logging them, but this one had so much multipath and fade the elements were smeared, making it hard copy.  The most sure thing was the call had RK in it, lol. They seem to be having about as much trouble as me lately, someone was calling RCV, RIW, and RIT in turn earlier today on 464 before finally finding someone to take his QTC.
TYhis was perhaps an hour before sunrise, so greyline propagashuns, replete with multipath, is my link to whoever is sending me soviet signals!

Send strong soviet signals, tovarich!

Rooskii militaryskii makes use of upper and lower sidebandskiis, one of the few military that does upper and lower. Not only do they often encroach the HAM bands with their nefarious ways, they also employ calls that are obviously US HAM calls in cw mode, such as N9KT and similar.
That said, these aren't naval calls for all I know, more like army, air defense, air force, or strategic rocket forces.
They also have no problem firing up cluster beacons in the HAM bands as well as gigantor radars.


"Cluster Beacons
A group of radio beacons with single-letter identifiers ("C", "D", "M", "S", "P", "A", "M" and "K") have been regularly reported near 3594, 4558, 5154, 7039, 8495, 10872, 13528, 16332 and 20048 kHz. The term "cluster beacons" is frequently used for them, as they transmit in parallel on frequencies only 0.1 kHz apart. These beacons transmit only their single-letter identifier in standard CW (A1A) using Morse code"
