Title: 11175 USB

11175 USB 1803Z 20DEC18

HOLD FAST in phone patch to SHEEP MAN via station DOWN DEEP for mux setup,

HOLD FAST wants to use a series of GEP's including stations STRINGENT and DEPENDENT, ending at station BEAT BACK, with RF16 and RF1 as the mux channels.

SHEEP MAN replies RF1 is reserved so will use RF12 and RF16.

HOLD FAST says wants to use 16 for the analog side, 12 for the digital.

The following is random chatter from HOLD FAST, might be mistakenly keying mic as only one side of convo heard;
"Go for HOLD FAST"
"Mission number 12085 tack 18"

I'm still waiting for them to show up on uhf mux and/or enter the net via hf.

Southwest 15 (commercial airliner) raises MAINSAIL on 11175 2105Z 03JAN19, asks if MAINSAIL is able to perform a selcall check for them, lol. MAINSAIL, who apparently doesn't realise this is a commercial flight, asks if they'd like a phone patch, Southwest 15 declines the pp and thanks MAINSAIL for the radio check. Been a long time since I heard commercial aviation on hfgcs.

He "sounded" ex mil, a lot of airline pilots got their wings in the USAF, so my guess is he knew exactly where he was radiowise.

Also, BOOK STORE calling ROTARIAN on triple one seven five @ 2210Z 04JAN19, ROTARIAN having read an eam a few mins ago.
ROTARIAN is distorted a good deal, and asks BOOK STORE to repeat last. Some triple one groundstas have been distorted lately.

BOOK STORE requests to check into net at this time.
ROTARIAN seems to be having trouble comprehending, asks BOOK STORE to stand by one mike.

ROTARIAN asks BOOK STORE to authenticate LFU.
BOOK STORE authenticates with J, and asks ROTARIAN to authenticate AUV.
ROTARIAN authenticate AUV with V, and shows BOOK STORE in the net at 2215Z.

Strong EAM coming across on 8992 USB, 11175 USB, 13200 USB and 15016 USB at 1747 UTC (nothing heard on 6712 USB or 6739 USB while the other freqs were active).  Best signals on 11175 kHz and 13200 kHz.  15016 kHz had a strong echo that the other frequencies didn't have.  Came across EAM on 8992 USB while tuning around for daytime pescadores/freebanders in the 8-9 MHz and 10-11 MHz regions on the COMMSIGMA KiwiSDR on the CT/MA border

6691 kHz USB - CA - Charlie Alpha

SKULL 12 has mask noise as well as jet engine noise, so kinda narrows down who it can be;

Is this just some civilian sailors talking on HF marine rigs? Any theory on the odd number and letter schemes? Thanks
Title: Re: 11175 USB
Post by: R4002 on February 13, 2019, 1817 UTC
11175 kHz USB is used by the US Air Force as part of their Global Communications System (HF-GCS).  Other frequencies used as part of this system include 4742 kHz USB, 6712 kHz USB, 6739 kHz USB, 8992 kHz USB, 13200 kHz USB and 15016 kHz USB.  11175 USB is the most active of these frequencies.  There are dozens of other "discrete" frequencies that are also part of the system.  11175 USB is used for Emergency Action Messages (EAMs) and other military communications in USB voice.

So short answer, no, its not fishermen, although they are found all over HF.  It's the US military.  The letter and number scheme are encrypted messages using a One-Time-Pad (OTP) encryption technique to send secure messages to military assets.

Thanks R4002. I'm familiar with numbers stations. Hadn't heard of this before now. The tone just seemed very laid back and not very professional compared to other more computer generated even toned voices. Wonder why Ive never seen this in the Spy numbers category?
Title: Re: 11175 USB
Post by: R4002 on February 13, 2019, 1907 UTC
I can certainly see the argument for putting it in the Spy Numbers section.  However, since 11175 USB (and the other HF-GCS frequencies) are used for two-way communications, telephone patches and other military voice communications its considered a utility network and not a spy numbers station. 

The operators on the HF-GCS will sometimes do some very entertaining things.  They are professionals, though.

On-going EAM at 1744 UTC with female operator on 11175 kHz USB.  Good signal on 13200 USB with some echo or long-path QRM.

EIMIHJZS2FC7AX3VP3KTGTMJW5S7JI THIS IS BLUEPRINT OUT at 1746 UTC.

At 1747 UTC, BLUEPRINT (same YL op) came back on with another ALL STATIONS, ALL STATIONS call, same echo/reverb-like QRM in the background (probably due to multipath).

At 1748 UTC, checked 13200 kHz USB and 15016 kHz USB, SIO 444 signals on those two frequencies as well, both exhibit minor multipath/echo QRM but the message is 100% readable.

6712 kHz USB is quiet, can hear something very faint on 6739 kHz USB, nothing on 4724 kHz USB and 8992 has a strong data signal on it with the EAM underneath (???)

At 1750 UTC, now male operator "message of 41 characters follows" (I missed the callsign while changing freqs)

Switched back up to 15016 USB at 1751 UTC (15016 kHz seems to have the best signal at the moment)

"Disregard this transmission, this is BLUEPRINT, out" at 1751 UTC.

1752 UTC - a second OM operator "All stations, all stations, this is BLUEPRINT, standby" into authentication sequence then alphanumeric message (on-going at 1753 UTC).  At 1754 UTC "This is BLUEPRINT, out"

Almost always have triple one playing in the background if I'm home. Since the Pro2 does dual watch I've triple one and the day primary for Trenton Mil playing, both freqs are on the fish finder display. I've tuned the lower half of 11MHz since I first got a stable hf rig in the late 80s, there's almost always something going on. Down the band you've got Russian Navy T600 (fsk mode) and USN Link11, further up there's worldwide HFDL and USAF ALE nets, ARINCs all over, RAF Vomit I mean Volmet, Asian pescadoreadors, everyone loves the lower half of 11MHz.

That splains the traffic on UHF earlier today complete with kazoo microphoned B2s. Also, HF propa has been amazingly poor the last few days, either the band is reeeeeally long or the propa just isn't going anywhere, so nice catch on Elmendorf.

On 03 May there was, for my logs, a record number of Skykings in a short period of time.

11 separate Skykings, with no errors or corrections, from 0052z to 0447z, 03 May, 2019.  That number matches one other date in my logs, 25 October, 2017, also 11 that day.  In 2015 I logged 12 on one day, but several of them were corrections ("ignore my last" etc).

I don't really do the HF-GCS network as such, but I do record a few other things nearly 24/7, and I end up catching a lot of HF-GCS traffic as collateral traffic.

Today around 1340Z there were three Akula bursts on either 11175 or 11232, something I've never heard on either freq before now. If anyone has a timestamped iq stream of this it'd be nice to have it. I was in the other room at the time, thus I didn't see what freq was being used. Rather cheeky of them to use either of these two freqs anyway. I suppose it's one way for the emitter to ensure the message gets to the command chain, as USAF and Canadian Air Force are top priorities for Russian sigint collection, meaning multiple Russian receivers are staring at HFGCS and Canadian mil radio freqs 24/7.

See here for Akula;

Earlier today I heard a E4/E6 flight authenticating into the net with CAT as part of the authentication process, just now at 2248Z another E4/E6 flight authenticated into the net with CAT. Just thought that kinda odd to use the same phonetics.

Since he sounded like he was using a kazoo for a mic my bet is a B2.

OFFUT interrupts MAINSAIL radio check from REACH 71 with radio check request. 1655Z 31MAY19

You're welcome on the correction. Sometimes they will change callsign abruptly but usually to something not related to their previous callsign - such as NO POND to MILL POND.

The nice lady in the naoc flight is simulkeying (my guess mistakenly) on hf, 11175 to be exact, and is discussing GEP channels to burn on;
"that's correct sir,
looking for analog 18 and digital 1,
sir we now have you loud and clear burning on 1, 
if we have some issues we'll give you a call"
