What is the USCG ENDGM all about?
A new Mode-S call sign has showed up in some of their MH-65 helos and it is a bit intriguing. We are seeing the Mode-S call sign ENDGM followed by the last two digits of the aircraft serial in some of their MH-65 Mode-S intercepts. The latest list I have is below all from southeast US ADS-B boxes.

Anybody want to hazard a guess what the USCG is using the Mode-S call sign ENDGM (probably short for End Game) for? Contact me via email at masthead address above.
