United 1948 called mainsail on 11175 on the evening of the 16th as well.

Woohoo. Hearing traffic on 322.400 MHz, supposedly this is New York ARTCC Big Flat RGAG? Hearing an OM assigning what sounds like local frequencies to various flights. A very strong signal.Woo!! There ya go!! Have fun.
Fairly confident the E4 you mention would be who I heard. What adsb map did you use to catch them?I saw it on ADSB exchange. I looked a few minutes ago and there was an E6 up in OK.

Could it be from a P8 Poseidon?
Mike
Far as I know only E4 and E6 carry the mux/ALCC system, mebber AF1 and AF2 do but not sure. Also, haven't seen a 4 or 6 via adsb maps in a while now, suspect they've stopped reporting, and for good reason.
Also;
"According to openly available data, the Dead Hand is an integral part of the “Zveno” system of air command posts, the development of which was carried out in the Soviet Union. The “Zveno” includes the airborne command and control post on the Il-86VKP aircraft, airborne radio relay on the Il-76RT aircraft, silo-based command missiles ‘Perimeter’ and mobile command missiles ‘Gorn’. In a period of threat, three Il-86VKPs would have the Supreme Commander-in-Chief of the Armed Forces, the Defense Minister and the Chief of the General Staff respectively on board. The Il-86VKP is able to launch an 8 km long antenna, which not even impulses from nuclear explosions can affect. Using this antenna the aircraft can transmit commands to launch all the country’s intercontinental missiles even if all underground command posts are destroyed by the aggressor’s nuclear strike. The radio relay aircraft Il-76RT would transmit commands to launch missiles in distant regions, including those deployed on submarines. In this way, the Dead Hand guarantees a devastating retaliatory strike in the event of communications disruption and the destruction of command posts after the first-strike surprise nuclear attack by the enemy. Its command missiles launch their warheads into space, where no hostile satellite or nuclear explosions can reach them and from there “wake up” nuclear forces to strike the aggressor."

Yeah not like there's 34 pages of frequencies and links to freqs right here or anything.
How location specific are the frequencies? It's not like it's HF where you have a chance of hearing it no matter your QTH
On this page, , is a box where you can enter your zip and see logs from within whatever rx range chosen;

Keep in mind that I routinely hear HUNTRESS and several other east coast commands here in sw Indiana, via an ancient scanner attached to a HAM triband vertical mobile antenna hanging in the window on the ground floor. When they're 50k ft up you can hear them a long ways.
I posted to the Scan-DC list asking about active frequencies in this area. We'll see what turns up.

I'd have to have a i/q of the entire sig to run it thru the batputer. Top o' me head says this was from the Sentry, with the BUFF you mention a close second.
As to the tacamo wideband mux, it's always wideband fm, 60kc wide I think, with various amplitude modulated sigs superimposed on the channelised mux stream. There will be two mux flowing, uplink and downlink, I'm not in range of any uplink that I know of, haven't heard any. There has been mention of a digital version to replace the analog wideband fm link but have yet to see it here. Somewhere around the start of this thread are some video links to steps taken by a monitor to extract specific channels from the mux, so you might take a look at them if you haven't.
Hi Mike, nice to have another ear aboard. Didn't have 351 in the rx, will see if anything pops up.
Hi Mike, nice to have another ear aboard. Didn't have 351 in the rx, will see if anything pops up.351.000 was different. Very strange. At first I thought it was interference so I tested it on three other scanners and SDR and all different antennas for each. I could post a short video of it here if I was able to.

SENTRY 06 (E-3B 964th AACS/ 552nd ACW Tinker AFB, OK) setting up air to air refuel with GETTY(?) 21 (GETTY DC CAP tanker) on 343.25 2145Z
06 tells 21 we're completing our first orbit, do you need more time?
