Does it start everyone out at London?

Yes, you need to drag that marker to your location. You can zoom in via one of the satellite maps (ESRI World) & put that marker right on your house. You need to go to the menu then look at the general tab. Click on "Set current location" & a marker appears. Then click on "Show current location", uncheck "Set current location" & you should have a little blue ball at your home. After that you can set range circles & filter for military aircraft only, through the same menu, using the "Map" tab & the "Filters" tab.

He (E-4B VIKING 18) flew just southwest of me then did a U turn back towards the NW. Still solid signal on 366.600. There are also a couple of E-6Bs out & about. PAID 85 bears watching, he's off to my northeast, but still out of UHF range.

AR307A 264.9MHz 25 Jan 2019 from 0345z; Nighttime KC-135 refuel C17 tfc until oth
Most times & frequencies posted are only an approximation.
Due to adulteration of the E.N.I.G.M.A. "designators" by others and not a match in the Conet Project they are never used.

E-6B BUSH 72 on 338.950 MHz (WBFM) & he just dropped the signal at 2021 UTC. I'm near central Kentucky.

No, he's still there. He may have switched to digital. There's a strong signal on 338.950, but no subcarriers are noted. 2025 UTC.

As you might have gathered I'm a bit of a newbie when it comes to the TACAMO/NEACP UHF systems and UHF mil air in general - I understand the UHF multiplexing concept and GEPs - some cursory Googling indicates that the system is eventually going to be upgraded to 100% digital encrypted IP-based using the same frequencies, is this not correct?  (something about "Project 411" or "Project 441"?)   Maybe I'm confusing the UHF air-to-ground system with the various military SATCOM upgrades.

Knowing the military they will retain backward-compatibility re: analog and connectivity to the HF-SSB networks.

Hmm. I wonder how well uhf digital modulation works in a nuclear fireball environment compared to uhf analog fm? The freq range (and power levels) used for mux is calculated to be resistant to nuclear fireball effects where it (the nuke) wipes out pretty much all radio waves for a short time and severely degrades others for a longer period within a few hundred miles of ground zero. In other words, apparently you can't send a signal thru a nuclear fireball from one side to the other, and some of the effects last due the volume of ionised air.

It wouldn't surprise me to see an upgraded mux, I mean they're trying to throw away one of the most effective warfighting platforms the US has ever developed (A10 Warthog), so why not ditch what works?

This site has a lot of info on the subject as far as hardware goes;
https://fas.org/nuke/guide/usa/c3i/index.html

However, the section marked Combat Ciders is actually Combat Cinders.

Also 366.600 just lit up with modem traffic on orderwire.
