Satellite, Radiosondes and Other VHF/UHF Signals / Re: UHF mil air

Thanks!


Neacp/tacamo/glass flight burning mux on 366.600MHz 2030Z 15JAN19
Modem traffic on orderwires.

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.

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.

Thanks for the details, and was just going to post that 337.3 lit up @ 1513Z today with modem traffic on orderwire pair.

The ADS-B site is a little flaky at times. They recently had to change from Google maps, due to costs, apparently, and for some reason, the site won't remember my range rings and location marker. I have to enable those each time I go to the web site. I'm sure there's a fix, but I really haven't had time to look at it.....I've just got too many projects and not enough "me"!

Cheater! Actually that's something I need to start doing. Do you do your own adsb receiving or do you use some webpage?
---
Go to this page: https://global.adsbexchange.com/VirtualRadar/desktop.html#

Then from Global Radar View go to Global Radar. Once you set your position, set up some range rings. I set mine at 50 mile intervals, out to a 300 mile distance. Then filter for only military aircraft & you're set. ADS-B doesn't always show E-4s & E-6s, sometimes they apparently turn off their equipment, but they show up enough to be really helpful. About 25 minutes ago, I saw a E-4B (COSTR 18) come up out of the SE & now I'm hearing him on 337.300.

Thanks for that, if I'd been thinking, I'd have scanned past the qsy to see if the other sig was still present and then I'd have known there were two flights.

Well, I was watching the flights on the ADS-B site, so I had some help!

Neacp/tacamo/glass flight burning mux on 366.600MHz 1842Z 11JAN19
DTMF and modem traffic on orderwires.
Abrupt qsy to 338.950 @ 1900Z, apparently transitioning to different GEP.

That activity actually came from 2 different aircraft. 366.600 was from E-4B VIKING 18 (73-1677) & following a little behind him was E-6B BURMA 63 (163920) on 338.950. Both aircraft came in from the NW & it looked like they were going to overfly my house, but they turned slightly south & missed me by about 25 miles. The E-4B continued to the SE, but the E-6B turned back to the NE & was heard for quite some time here. I'm in the central part of Kentucky.

Definitely EAM like but not EAM. Example log from today, 8 Nov 2018

As indicated in an earlier post, a number of frequencies have been in use today by USN assets (ships, aircraft & submarines) in a exercise to "practice" both sending & receiving EAMs.

Heard two of them today (8 Nov2018). Station IDed as "Q0D" (second character "zero"). Sounds exactly like an HFGCS EAM, but there was no parallel activity on the normal HFGCS frequencies. Could this be Canadian military? Googling doesn't produce any info for me.
-----
Those are USN assets participating in a exercise. a large number of frequencies have been in use since this morning. 12082.0 & 7498.0 were active a few minutes ago, both USB voice.
-----
6778.0 was just active with 8UN sending a EAM. 2125 UTC.

I had a feeling it was MARS or military in origin.  I've heard data transmissions on 6907 USB in the past so that also makes sense.
---
I forgot to mention, the data transmissions are generally MIL-STD 188-110A, but it's encrypted almost all of the time.

Of course 6765.0, 6845.0 & 6910.0 are primary SHARES Regional frequencies. Since some MARS stations participate in SHARES, you'll hear them there, during SHARES nets. 6910.0 is also a MARS ALE frequency. Other MARS frequencies in the range you asked about, include 6907.0 (already noted), 6818.5, 6850.5, 6913.0, 6968.5 (already noted) & 6996.0. I don't normally follow MARS much except during their national exercises, so I may have missed one or two. 6913.0 may or may not be a current frequency. The last note on it I have was from a couple of years ago. All frequencies are USB. I feel like I'm missing some USAF MARS freqs between 6700.0 & 6800.0, but I'm drawing a blank right now....

12
Those are US Army MARS ALE addresses. 6907.0 is one of a number of USA MARS ALE frequencies.

13
It's been on 8 MHz tonight (0250-0300 UTC) July 20, 2018. Frequencies were 8164.0, 8154.0, 8189.0, 8224.0, 8194.0, 8184.0, 8144.0, 8164.0, 8159.0, 8229.0, 8174.0, 8164.0 & on & on, jumping around every few seconds, but staying longer on some frequencies.

14
Airborne Command Post aircraft, likely E-6Bs or maybe a E-6B & a ground station. These type comms are heard here often, generally moving here from 11175.0 as one station enters the net. IIRC, this is called the CHARLIE ECHO window.

There are also TELCO stations that check into the nets. TELCO stations have an important NS/EP (National Security/Emergency Preparedness) role in disaster communications.
