Record for me stands at 596 characters. It was March 19th, 2003. Sent by callsign Vengeance, relayed by Skymaster callsign Seraphim. Just 34mins later the 160th SOAR and 22nd STS made a beeline into Iraq to begin the invasion.



Same message, just being repeated and relayed yet again. Something's up.
596 is just nuts. Did that one ever get sorted out by your group?

Mainsail callsigns change every 24hrs at 23:59 UTC, and are rarely repeated. Most base transmissions originate from the 789th CS in Andrews via the networked HFGCS sites. Though messages can originate from bases which host spoke units of the HFGCS mission. Aircraft callsigns are generally consistently used unit callsigns, to which I'll link to a list below. As to the big three:

Skyking = Any or all Single Integrated Operation Plan Aircraft and Strategic Weapons Airframes

Skybird = Any or All STRATCOM command posts, launch control centers, HFGCS stations, Air Traffic Control on Air Combat Command / Air Mobility Command (REACH) host tenant bases, SSB HF radio stations, and joint air defense sites in Canada.

Skymaster = Any or all STRATCOM airborne Command & Control aircraft. (To date all OSINT indicates it must be in flight).

------------------------------------------------------------------

HFGCS Sites/Facilities:

Andersen AB, Guam
Ascension Island
Barksdale AB, Louisiana
Croughton AB, United Kingdom
Diego Garcia Naval Station, Indian Ocean
Elmendorf AFB, Alaska
Hickam AB, Hawaii
Keflavik NAS, Iceland
Lajes AB, Azores
McClellan, California
Offutt AFB, Nebraska
Salinas, Puerto Rico
Sigonella Naval Station, Italy
Yokota AB, Japan

Another very long EAM strongest in 15016kHz at 2055UTC. I'll give the character count after it's over and the callsign.
EDIT: 220 characters, callsign BANKRUPT.

The same EAM message of 144 characters repeated 4x tonight along with an RTTY signal on all channels EAM was transmitted on. Began at approx. 0145z

45NPO - PTWMNBPUXWPVXWT5L4BT7PT6RTJ662NDTQSLSUKT4P6HJSQJ6AONNTVTGNFFFFVJJNTP4R7XNB3UBKUAC4WUUPIQFAHZUJH66Z3B3DUUWWU2XXXXOKE2EHHMMAATVVXZZOEEEERTVTIH

I was on it too. Strongest here on 4724kHz. Must've been the west coast relay on that frequency.

Yeah, one of my online friends copied it on 4724 as well.

On a side note, there was a E-6B ("HISS19", 163919, AE0411) out of Tinker heading west. Disappeared from ads-b around SW Colorado.

It's a simulcast. All transmitters at all times, on all frequencies unless specified otherwise. The frequency schedule only applies to the ground station at the transceiver site, and changes between summer and winter. The reason you had such strong reception was more than likely propagation and your proximity to Beale. 80m was open last night which logically indicates that 4724kHz would be as well more than likely.

Hello all. Could these extended character EAM's be the result of North Korean Premier Kim Jong-Un's post surgery grave condition which President Trump alluded to on CNN today?

We will never know for sure. We can make assumptions and yes, this series of EAMs were occurring as the Kim news was breaking worldwide. All we can say is that yes, they could have been related but on the other hand, it could have been something totally unrelated.

When I watched the messages for some years I had a classification system.
That one (if copied correctly) would be classified as a C144Q3 in my system.

I'm pretty sure I got it right. I compared notes with an online friend who also copied it down :)

Please feel free to expound on your system if you wish. I am interested.

lots of comms on 11175 with skymaster back on 5/7
are any of the callsigns heard from nuke subs or nuke silos?

Skymaster is the collective callsign for all USSTRATCOM airborne command units. Any communications with Skymaster would be ground to command post, and then Skymaster would relay to the airborne units party to the operation.
