Yeah, I would go with B-2 also. Although, it "DEATH" might be a tactical call, and not one on a list.
I am not sure, but I think the A-10 has no SSB HF capability. They have a lot of radios to talk with people on the ground, but I don't think any are SSB.

I did not hear any myself, but there were SKYMASTER-format messages today. Mercury E6B AE0412 (https://globe.adsbexchange.com/?icao=ae0412&lat=53.955&lon=0.357&zoom=4.9&showTrace=2024-02-07), which was in Europe, was broadcasting as POSTULATE. Messages were repeats of EAMs (or FDMs) broadcast by ground station. POSTULATE also confirmed receipt of SKYMASTER-format messages from MALT 11. Reports from listeners on the UTwente WebSDR (Netherlands) – I was listening with KiwiSDR in Kansas and, as one could probably expect in the case of messages being broadcast an ocean away, did not hear anything from POSTULATE or MALT 11. (Though the ID/location of MALT 11 is non-obvious to me.)
SKYMASTER events are poorly documented online but do seem to be fairly predictable. For the event a few weeks ago;
- Jan 15 2020 was the third Wednesday of 2020
- 2021, 2022 dates I have not found mention of online
- Jan 11 2023 was the second Wednesday of 2023
- For 2024 you could've expected a SKYMASTER event on either the second or third Wednesday of this year, and you'd be about right the second time – the Jan 11 2024 messages came, going by US timezones, on the third Wednesday of this year.
Some reference dates for today;
- Feb 10 2021 was the sixth Wednesday of 2022
- Feb 01 2023 was the fifth Wednesday of 2023
- And so for 2024 you'd again be in a position of an either/or – either the fifth Wednesday of the year (Jan 31) or the sixth (Feb 07), and you'd be right the second time.
Hopefully someone will report in the thread if they did hear messages today and can share times, etc. but even failing that I wanted to share this information. I have done various web searches, checked random Discord servers, trawled even through Russian language SWL forums, etc. to find some dates. I am not definite on when the next SKYMASTER event could be expected – a quick re-check of some posts suggests some kind of 'follow up' could happen within the next few days or possibly this weekend, but I am not sure. From my own notes I heard SKYMASTER messages on a weekend in April of 2023.

* TAVA 44 originally misidentified itself as FIAT 32 to deliver message and amended itself twice.
** Suspect all KIVA/RIKA/RICO were actually PLICA – "PLICA" confirmed via phonetic spelling in contact with Gander radio; [link (https://twitter.com/thenewarea51/status/1780832941326619098)].
*** As observed during the January 11 event, it is almost like there are "3 SKYMASTERS" – one for the US east coast, one for the US west coast, and one for the US central region. My impression is that E6s were serving this role under callsigns BACKBENCH, BACHELOR, and CULINARY, respectively.
**** It is quite likely that some of my transcriptions have mixed up BACHELOR/BACKBENCH. Reception wildly varied per SDR and all were affected by a great deal of background noise for the duration of this event.
274 message;
04:07 CULINARY PIL UQY BIK WPD XKD TAJ
Aside; there were also 274 messages broadcast April 10 and 11. It is not obvious if those messages automatically 'connect' with the SKYMASTER traffic on April 12, but it does not seem horribly unreasonable to connect the dots there.
Additional messages;
Additional messages were broadcast under 3 character callsigns on 5074 kHz, 6778 kHz, 6807 kHz, 7594 kHz, 7703 kHz, 9883 kHz, and 10674 kHz. Many of the messages were identical to message traffic on primary HFGCS frequencies (but did not follow the typical "ALL STATIONS" format or have an addressee. The 'format'/delivery was not consistent; e.g. in at least one case, what had been broadcast as a 'standard' 30 character message on a primary HFGCS frequency was read off in groups of 3 characters to comprise a message of "3-0 characters". (There were some messages delivered using what I thought was an intentionally comic tone of voice, and others an overly slow delivery. While in at least one instance I thought I recognized the voice of an HFGCS operator, from context, this is probably unlikely.)
Unlike my previous post in this thread where I felt like it was reasonable to expect more SKYMASTER messages 'sometime in April', I feel I do not have enough information to correctly anticipate the next one. Around late August/early September I am expecting another event like this one to occur, but for May – July I am going to have to look through the past documentation of SKYMASTER events on www.radioscanner.ru to see what activity has typically been like during this time of the year. (I have seen some 'reputable' people in the SWL community incorrectly reporting there has been an increase in the frequency of these events since early 2023 – there is more than enough evidence to the contrary for those who are interested in looking for it.)
