New HFGCS Callsigns.

[TheArtist]

Over the past couple of days I've noticed on the USAF HFGCS system the use of a new callsign every 4-6 hours or so. No more "Mainsail". I've heard: Abundant, Toy Shop, Sombrero, Rearguard, and Majority.

The only thing I could find was Sombrero being the callsign for the 31st in Italy.

I assume it means just about zero but if anyone has any information or guesses why they'd be changing so much on the sign out, it would be interesting to know.

Mainsail is still used heavily they were just on a few minutes ago

Interesting.

There's also another one I've heard 3 times this morning. Last transmission was 1225 EDT. Call sign was Railroad, and it had digital carrier waves on the upper sideband. At least the messages were only repeated twice instead of 3 times. I retract last statement--meaning now 4 messages from railroad, this time with huge interference on the LSB. Message only repeated twice.

Thanks guys! I'll try to keep listening.
