HFGCS Force Directional Message (FDM) and Emergency Action Message (EAM) Log

[INTERNETFRIEND]

Note: The 02:05Z msg was broadcast from an alternate NCS using new digital link equipment.

To me it sounds like they've fallen back to using whatever the previous method the alternate NCS used was.

Here is why the new HFGCS digital equipment may appear to sound strange. First, it has no lower band-pass filter. As can be seen in the image bellow, the audio extends well bellow the centre carrier by at least 3 kHz. The USB is also approx 6 kHz wide. Military HF stations typically operate with 3.2 kHz or 3.6 kHz filters as the extra bandwidth is required to support secure communications equipment and various STANAG data modes. In either case, USB and LSB band-pass is respected, which in this case is clearly not.

The new method as seen last week and during the day today does actually seem to have band-pass filters, and this 'splatter' past the ~3 kHz filter is nothing new for HFGCS broadcasts – it has sporadically occurred in the past. My hunch is that for this evening the alternate NCS has fallen back to using whatever previous method they used for broadcasts was as, if any issues come up with the new method during the night, the relevant individuals may not be on hand to troubleshoot.


EDIT: A possibility for an apparent discrepancy in what we are hearing might be because individual stations may be broadcasting things 'separately' (note here I am not talking about Andrews vs Grand Forks, but rather Andrews vs Offutt vs Beale, etc.). There has been some odd sort of divergence I've noticed the last few months where some of the relay stations do not seem to broadcast at night, or maybe are not broadcasting on all frequencies, or something to that effect. The last few weeks this has become even more complex, as apparently some listeners of the new 'digital link messages' using the UTwente SDR in Europe have reported that they are not hearing any audio distortion or 'glitchiness' during broadcasts where I most certainly have been.

This all gets confusing when you consider that of course a listener's experience is not definitive as propagation, etc. can vary the individual's experience to pick up messages, but I do think there has been some kind of divergence that's begun in the last few months – or if it existed before, is only now beginning to be noticed and documented. Perhaps you are picking up broadcasts from one of the ground stations that are using the new method and it is again experiencing issues, but to me it sounds fine – much like last week the new method sounded glitchy and inaudible at times, but listeners in Europe said it was fine.

It seems to have been the case for most if not all of today for messages to first be broadcast using the "old method" and then shortly after broadcast again using the "new method". From Kansas, the old method seems to be becoming much weaker and the new method is continuing to come in crystal clear, with the 'glitchy' audio issue resolved. Here is a quick comparison of how reception looks visually;

[~SIGINT~]

There has been some odd sort of divergence I've noticed the last few months

I have noticed the same and attribute it to the HFGCS system upgrades. Many sites are receiving antennae upgrades as the antennae are some 30 plus years old. The antenna fields also no longer meet modern safety code requirements. This will see entire antenna fields go "off-line" as no person with a right mind will work in a "hot" antennae farm. I believe that divergence is temporary ... for the next little while (perhaps years).

This is nothing new for longer messages but the first string being 87 characters long does not seem usual for 166 character messages. Comparing against 3 other 166 character messages broadcast last year, all 3 had a 41/18/18/18/55 character format, in contrast to today's 87/18/18/18/9 character format. This might pique one's interest in a possible purpose of the LO prefix, which has previously been used on Jan 20, 24, and 31.

INTERNETFRIEND: Thank you for the clarification. The use of "FOR" and "4" was very confusing.
... interesting messages, I have a few of these "4" preambles in my log file but I believe these are the only ones with a "MESSAGE OF xx CHARACTERS".

[INTERNETFRIEND]

Note: I am missing something here ... the character count does not match the msg content.

It's not "FOR MIKE," it's "4M". You can tell it is part of the EAM because they repeat it as the preamble 3 times; if it was an addressee of a direct EAM they'd only be repeating it twice. This will give you 43 characters for both messages.

They're quite interesting messages, I think. This is possibly how to break them apart;

Edit:
The 37 character message seems to fit this pattern fine, dropping one of the possible 5 character sections. I am less sure of the 33 character message;
