Josh, where are you located and what do you mean by "burning mux"?  Are you talking about a multiplexed signal or mux = music?

Sorry about the elementary questions.  You've got a lot of logs so I presume you're in an area of heavy military aircraft activity and have a quality monitoring setup. 
Title: Re: UHF mil air
Post by: Josh on April 27, 2017, 1722 UTC
Today our friends were noted on 337.3 @ 1400Z burning (sending) mux 1 or mux 2, a multiplexed (as you expected) rf stream that will include voice and digital and digital voice and anything else they can think of sending, you'll hear a carrier of several KHz on the frequency when they're muxing about up there so you know when you've found them. In setup for a mission you will often overhear the stations mention they're up and "burning" on "RF13" or some other channel descriptor. If you hear some bleeps and bloops like dtmf tones you might expect a phone patch to take place, or sometimes the carrier just drops as they've qsy'd to some other channel to burn on, or have closed the link.

I'm conveniently located in the Midwest where I can hear this traffic that apparently often orbits near the Ohio/Kentucky/Indiana region.
At 40k ft the uhf line of sight is 250mi or so, and they're running a lot of power to very efficient antennas so they have a good bit of UHF range.

Here's some info about what's going on, pay attention to the naoc and tacamo in the image;

Josh,

Thank you for clearing that up - I had a feeling you meant multiplexed (as a TACAMO plane transmitting music on a UHF military frequency makes little sense to me).  So they simply use chunks of the vast 225-400 MHz band and multiplex voice/data on a wideband carrier, switching frequencies as they move and/or as the operational conditions warrant.  Sounds like you've got a good monitoring location and setup.  Naturally these guys are running power and high gain antennas.  Even without those, they're 40,000 feet up, as you've said.

Title: Re: UHF mil air
Post by: Josh on May 01, 2017, 1624 UTC
Lol I don't know about a good setup for this stuff. Right now it's a Uniden BC9000 fed by a 2m/70cm HAM mobile antenna hanging in the window. The saving grace is the fact the coax run's real short so what sigs do make it to the antennae suffer little loss getting to the scanner.

That being said, soon the permanent V/UHF receive setup will be going up, a Discone fed with 9913 coax and some other antennas such as a turnstyle for the milsats and some others focused on the 220 to 400 range. Various splitters and antennae switches will pipe the rf to various receivers. Then the serious V/UHF monitoring will commence with a RTL dongle feeding decoder apps in the pc. That's the plan at least, as they say in Russia; vsyo na bumage, it's all on paper.

The tacamo ac may also be sending msk on vlf; 17.9kc being one of their noted freqs but they may also occupy other near freqs. Bw for msk will be 190Hz, 400Hz, and 800Hz. A dgps decoder will try to grab something from this signal however traffic is encrypted.

Thanks for the freqs, do you use the 2006 for mil air? The 2006 was my first mil air rx back in the day, good enough to catch satcoms sitting on the kitchen counter with just the factory whip antenna screwed into the case.

Thanks for the resources!

No, right now the 2006 is next to my bed with a whip scanning the local HAM repeaters.  I've been using the 780XLT attached to the outside antenna to search for milair because the software will record the frequencies it finds.  Back in the day, I had a pro-2035 (I think that's the model) with an optoelectronics board in it.  I bought it used for that purpose because I couldn't deal with the thought of carving up my 2006 to put the opto board in.  :o

I will probably use the 2006 for milair once I get a cache of frequencies.  I also plan to make and use an antenna tuned for that band (right now I'm using a discone).
Title: Re: UHF mil air
Post by: Josh on May 19, 2017, 1529 UTC
Sounds like you know your way around. Likewise I refused to cut up my 2006 for the same reason, however it did do very well at mil air. Always wanted to add some foil to its insides to block rf, shame they didn't make metal cases for it like they did with the 2004. Lol still have all the Bill Cheek scanner mod books sitting here, have to look them over. Likewise I need to get some antennae for dedicated mil air, a turnstyle for the sats and a discone cut for 220 to 400. I've also considered a off center fed vertical dipole for 220/400 as they have low swr every other MHz when designed for hf, perhaps even better bandwidth at uhf and are less fiddly to build than a discone, however it's not too hard to cut down the typical v/uhf discone for the band in question. Also been prodding a manufacturer I know to roll out a 220 to 400 bandpass filter that should help in high power v/uhf signal areas

Northstar C3 Wideband Multiplexed System:
The system onboard the E-6B TACAMO, Air Force 1, The E4B NAOC and other aircraft that provides connectivity into the Northstar network via Ground Entry Points (GEP) is the UHF frequency division multiplexed (FDM) command, control, and communications (C3) system. Both commercial and military networks can be accessed. The onboard components consist of three UHF AN/ARC-171-1H transceivers, five UHF antennas, three MD-1172 modems, three multiplexers, and associated hardware. Currently, the equipment provides three of any combination of the following four services:
- UHF FDM (up to three full-duplex groups of up to15 channels each)
- Airborne Launch Control System (ALCS) data links
- Conventional UHF AM line-of-sight (LOS) (up to three half-duplex channels)
- UHF SATCOM phase shift keying (PSK) receive-only channel (TACAMO broadcast)
A UHF LOS air-to-ground configuration is used in conjunction with the ALCS for communications to intercontinental ballistic missiles. In peacetime, the ALCS is used only during exercises in certain geographic regions within LOS of missile silos. The 75 baud UHF SATCOM data (TACAMO broadcast) is simultaneously broadcast on HF and can be received via that medium. Therefore, much of the time, the third ARC-171 is available for other missions or functions. Nominally, at 25,000 feet, connectivity is provided at an aircraft distance of up to 180 nmi from a GEP. GEP stations are usually located at elevated sites for maximum unobstructed view. Towers are used to elevate antennas in flat areas. Separate transmit and receive omnidirectional antennas are used. All sites are terrestrially connected via AT&T T-1 lines.
The current Air-to-GEP interface is a full duplex UHF FDM link that provides up to 1000 Watts of power and 12 full duplex voice channels per FDM group. GEP sites have at least two radios and two compatible multiplexers. The channels are frequency multiplexed into a 60 kHz baseband group consisting of twelve 3 kHz full duplex voice channels and three orderwire channels plus guard bands and then frequency modulated for transmission on a UHF channel.
Principal sites at Waldorf, MD, Omaha, NE and Lamar, CO are connected via multiple T-1 lines. The primary ground control site for the entire network is the Special Government Operations Center (SGOC) at Waldorf, MD. The secondary ground control site is at Offutt AFB, NE

"I use a 2 step process to listen to WBFM. First I record the RF signal in FM mode with a bandwidth of at least 120 KHz. I then play that audio file back to tune the sub channels. The audio signal from the E-6 is about 60 Khz wide and the sub channels are spaced 8 Khz appart both USB and LSB. The first video shows the second step. Here we have the E-6 Absentee making the initial contact with the Network coordinator (Gass House). This is done on the sub channel orderwire bravo at 8 KHz LSB. Orderwire alpha is at 0 KHz and orderewire Charlie is at 8 KHz USB. Absentee passes the "flight plan" that lets the Network coordinator know what GEP stations Absentee is going to be using. In this case it's stations Ant House and possibly Affluence. Absentee also passes a mission #. This is the only routine traffic that I hear out on the West coast other than terminating the link at the end of a flight. I do catch a phone call ocassionaly and one is made here on 56 KHz USB. It is a DSN call where Absentee informs someone the are executing exercise GSRV.

I rarely get a good signal from the Beale GEP. Here are the better catches.

STRATCOM GOC can be heard a few times switching to secure comms in this one
https://drive.google.com/file/d/0B52...dEci1tdm8/view

Here is another where I do my best to show the steps I use including a necessary change in the SDR# config file to get the necessary bandwidth in NFM mode. WFM mode will not work. It filters the audio whether the Filter audio box is checked or not.

New freq, strong sig with ssb voice on orderwire alpha, must be close.

A hint on catching these guys is to use am mode. The main carrier is at the center of the working freq and will always stop the scanner in am mode on this signal. If you scan with wide or narrow fm the scanner will typically blow right past the sig on a default squelch setting. Once you find the sig, lock the scanner on freq and then open the squelch so you can try nfm and wfm modes to see what you get. I typically only use am mode however, using slope detection via the am modulator on the wideband (60khz) fm signal thus missing out on most of the signal as most am filters in typical scanners are only some 15 to 30Khz wide, but am allows you to 1) pick up the signal easily even when weak, and 2) to demod the orderwire pair at the carrier of the fm signal. Well, since you're using am and the orderwire voice traffic is always ssb you're listening to ssb with an am demodulator, but you can still follow along with some difficulty. A sdr system will be much more versatile.

383.55MHz is interesting in that it's a freq often found in military base trunked repeater systems across the US, however as nbfm mode. It's also a freq in AF1 trunked radio sys that is inherent to the plane. This makes me wonder if some of the bases are also set up as GEP (Ground Entry Point aka a T1 link to the commercial US telecomms network as well as secure US mil networks) for Neacp/tacamo/glass.

As part of the training the boom operator sometimes orders the pilots around quite a bit, say as in moving them from a few feet to several hundred feet in any axis, disconnects on them without warning, etc etc to train them for contingencies in less than ideal conditions.

Serial Number Criteria: 89-0128
Description Criteria:
Data last updated: Tue Mar 15 09:25:04 2016

89-0127 ... 89-0129 (EXACT MATCH)
Northrop B-2A Block 10 Spirit
0127 AV-12 MSN 1012 *Spirit of Kansas*.  Upgraded to Block 20 1996, to Block 30 1998.
Made the first landing of a B-2 in Australlia, at RAAF
Darwin, Northern Territory Jul 27, 2006.  Crashed on takeoff
from Andersen AFB, Guam Feb 23, 2008 (509th BW, 393rd BS).  Both crew ejected safely.
Crew reported an onboard fire, followed by uncontrollable roll
to starboard.  cause of crash was a corruption of the plane's
air data system, caused by presence of moisture in system during
calibration.
0128 AV-13 MSN 1013 *Spirit of Nebraska*.  Upgraded to Block 20 1996, to Block 30 1999.
0129 AV-14 MSN 1014 *Spirit of Georgia*.  Upgraded to Block 20 1997, to Block 30 1999.

Th last few nights late they've been using this freq for whatever reason, wondered why I hadn't been hearing them during the daytime like normal.

Yesterday, tacamo/neacp was within earshot for most of the day on 337.3, wich is the longest I've ever copied them. Kinda made me wonder if something was going on globally or perhaps an exercise. North Korea upping the ante with more threats/promises was my first thought.

On the 3rd or 4th I had what seemed to be two Northstars up and running on different freqs, maybe I caught a E-4 and E-6 up at the same time? That or maybe was getting the ground entry point via tropo ducting. The exercise made me suspect it was a 4 and a 6 up there muxing about rather than tropo.

An AWACS was stopping the scanner with HAVE QUICK time synchs for a few hours earlier today. Later I fired up an ale decoder on 11181KHz and caught what I presume to be the AWACS in question;

Normally, the AWACS will do some 110A mode work with a ale linked AFB and I had a 110A decoder running to catch them, but the AWACS didn't send any 110A on 11181KHz today. Sometimes the ale modem decides another freq is better to use and I wasn't ale scanning so missed any.

And HAPPY 61 is the call sign for planes of the 126th Air Refueling Wing out of IL's Scott AFB.  This unit is part of the Illinois Air National Guard.

This is almost daily inflight refuel training. The typical customer is a large multi engine ac to support several pilots getting training in the shortest time possible by just seat swaps. I have caught some interesting ac in mid air refuels to include a B2 and I think a U2. Nothing indicative of imminent nukes flying today at least.

PEACH 88 and unid presumed HAPPY 61 tanker doing aar.There are two tankers and their partners in the track.

61; Back four
PEACH 88; Moving back.

61; Up four.
61; Forward four.
61; 61 disconnect!

61; 88 we're clear to do another 45 minutes.
PEACH 88; great thanks.


PEACH 88 resolves to PEACH/PEACHTREE OPS 116th/461st ACW CP GA ANG WARNER-ROBBINS GA
meaning the ac in question is likely a E-8 J-STARS .

61's 59-1444 tail number resolves to a KC-135R tanker, made in 1959.

06 unid ac
51 presumed tanker
If you don't catch them as they meet up and discuss the training needs for the day you might never hear their actual callsign or the juicy tail numbers that id a particular ac.

51; did you guys get a contact light on that?
06; negative.

If you note that the same gep freq is employed for the same ac freq please share, I can't hear any gep here so was wondering if they can move around regardless of offset or if the duplex link is set to specific pairs or at least a specific offset.

396.200 MHz!

Is there still extensive use of the 380-400 MHz portion now that military UHF-low Project 25 digital trunking land mobile systems use this frequency range as well? 

It's 380-390 MHz for the repeater outputs and 390-400 MHz for the inputs, save for 14 channels assigned as "Intra-Squad Radio" (basically Icom FRS HTs with military frequencies programmed in them - the Civil Air Patrol are/were known users).  Apparently there are also extensive use of Motorola XTS2500 series radios (380 MHz to 430 MHz UHF low split) used one the P25 UHF low systems and for ISR purposes. 

Intra Squad Radio
Channel 1 - 396.875 MHz
Channel 2 - 397.125 MHz
Channel 3 - 397.175 MHz
Channel 4 - 397.375 MHz
Channel 5 - 397.425 MHz
Channel 6 - 397.475 MHz
Channel 7 - 397.550 MHz
Channel 8 - 397.950 MHz
Channel 9 - 398.050 MHz
Channel 10 - 399.425 MHz
Channel 11 - 399.475 MHz
Channel 12 - 399.725 MHz
Channel 13 - 399.925 MHz
Channel 14 - 399.975 MHz

The 380-400 MHz trunking systems use 12.5 kHz spacing so the potential for interference with aircraft comms exists.  I was under the impression that military aircraft frequencies in the 380-400 range had moved down below 380.000 MHz
Title: Re: UHF mil air
Post by: autovon on October 17, 2018, 0112 UTC
1.  There are still a few aircraft frequencies still in use up there, both on the tactical side and ATC side.   I don't think there was the mass exodus as propagated on various milair message boards and email lists. 

2. The ISR radios/frequencies were a someones good idea fairy that don't really get used.
Title: Re: UHF mil air
Post by: R4002 on October 17, 2018, 1310 UTC
Right.  I think the ISR was more an answer to the military using off the shelf FRS radios (which is apparently strictly forbidden).  As long as they're not close to a 380 MHz - 400 MHz LMR system operating near the aircraft freq in question I suppose there's no reason to move down below 380.000 MHz. 
Title: Re: UHF mil air
Post by: autovon on October 17, 2018, 1336 UTC
Yeah, I imagine what happens is many didn't move unless the user reported interference.   There was a form that NITA frequency users could fill out for things like interference.  That would go to whatever hole that government forms go to to hopefully get solved in a few decades.
Title: Re: UHF mil air
Post by: R4002 on October 17, 2018, 1343 UTC
Here are the two larger UHF-low 380-400 MHz military LMR trunking systems in operation...

United States Department of Defense [System 14C] - http://www.radioreference.com/apps/db/?sid=3856 (http://www.radioreference.com/apps/db/?sid=3856)

Joint National Capital Region [not just around the DC area] - http://www.radioreference.com/apps/db/?sid=4699 (http://www.radioreference.com/apps/db/?sid=4699)

The US Department of Defense system is massive, but there are several other regional and local systems using the same 380 MHz range that are either linked to each other or stand alone for whichever reason.  There is still extensive government use of the 406-420 MHz range, whereas 380-400 MHz is apparently military only.

Very true.  Install Cobra 29 CB radios and Wilson magnetic mount CB antennas in/on your military transport trucks in Iraq because for some reason the Army install SINCGARS VHF-FM 30-88 MHz gear in those trucks?  check.   Buy Baofeng UV-5Rs for your Russian special forces unit in Ukraine? check.  I'd say FRS radios are certainly "mission capable" :D

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.

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.

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"!

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.

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.

Post by: Josh on January 31, 2019, 2050 UTC
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.

Some light reading on the effects of nuclear fireballs on radio propagation;
https://apps.dtic.mil/dtic/tr/fulltext/u2/a044561.pdf
https://apps.dtic.mil/dtic/tr/fulltext/u2/427020.pdf


This is interesting;
"High-altitude nuclear tests were made in 1958 and 1962 at different heights above the mid-Pacific area. Observations reveal MF and HF propagation anomalies caused by H-bomb-induced ionisation in the ionospheric D region, the effect on which varied with burst height of the explosion.
Periods of abnormal ionisation in the F region at Rarotonga after both of the explosions in 1958 are ascribed by Cummack and King (1959) to an upward movement of gas into the F region, where high compression ratios following the blast wave resulted in ionisation by collision. Abnormal F-region ionisation at the Pacific control point enabled enhanced reception in Wellington of 25 Mc/s and 21 Mc/s transmissions for several hours after the 1958 events. Similar enhancement of transmissions on 21 Mc/s-s
the highest frequency then in use by the BBC-was again observed following the July 1962 explosion."

"Come up to 377.12." (377.12 is Camp Atterbury MOA)

"Afirm in the climb two six zero."

"They probably terminated it once we got into the restricted area"

"They probably didn't like the delay" (this I think gives it away as drone operators as there's a delay involved when a drone is in direct contact with civilian flight operations yet the drone operator communications is delayed due the satellite link to the drone)

"About 3700 pounds of everything"
"Showing 27 knots out of the southwest"

Another giveaway is there will be no mask noise or jet sound in the background since the audio is generated by uav pilots in a comfy air conditioned and finely appointed ground control station. The drone simply relays the comms between the local flight controllers the drone is in range of, and the remote pilot.

Is 303.000 MHz akin to 123.450 MHz on the VHF air band?  Sort of the air-to-air chat frequency?  I can see who it would be easy to remember - 303.000 = "thirty thirty" or "three oh three"?   I bet 345.600 MHz, 357.000 MHz, 308.000 MHz and similar are also used? 
Title: Re: UHF mil air
Post by: Josh on July 15, 2019, 1915 UTC
If I caught the tx that means it was preprogrammed into the scanner currently in use, meaning it was confirmed as an active freq by me as well as others. Sadly I didn't bother to use alphanumerics to label the channel, argh!

More to your point, I agree this is likely a cb channel for convoys, but I'd have to double check the db to see what it's listed as.
Title: Re: UHF mil air
Post by: R4002 on July 16, 2019, 1643 UTC
I did some Googling and apparently there are several of these frequencies in use for air-to-air chat, similar to the way civilian pilots use 123.450 MHz and 123.475 MHz.

They include, but aren't limited to:

234.500 MHz - "Straight"
234.550 MHz - "Straight 5"
299.500 MHz - "Cheap Suit"
300.600 MHz - "Thirty aught Six"
303.000 MHz - "Thirty Thirty" "Winchester" or "Three Oh Three"
303.050 MHz - "Winchester 5"
333.000 MHz - "Triple 3”
333.300 MHz - “Quad 3”
333.550 MHz - “Full House”
345.600 MHz - "Straight" (see also: 234.5 MHz)
351.000 MHz - Haircut
357.000 MHz - "Magnum"
384.500 MHz - "Pistol"
399.950 MHz - "Penthouse"

It seems like specific units have others, often nearby these (for example, there's a "Magnum 5", 357.050 MHz), and others.  Of course, there are the specific units' present channels, often referred to us "push 3" or "button 3" for preset 3, for example.  There's also the 137-144 MHz and 148-150 MHz ranges for AM air to air voice.

Awesome work, will have to put them into scan. These are kinda similar to the hf channel that used to get more USAF activity than it does now, 6761. That freq was treated like a party line for bombers, tankers, everyone.

I’ve heard chatter on 6761 kHz USB a few times too.

In a weird way, it’s like the pescadores and freebanders on HF.  They like easy-to-remember frequencies.  343.400 MHz, 6666.6 kHz, 6363 kHz, 40.40 MHz, 30.30 MHz, 45.45 MHz, 7676.7 kHz and so many others come to mind. Frequencies like 123.450 MHz and 246.800 MHz are super easy to remember.  Same with the often-overlooked 137-144 MHz and 148-150 MHz VHF bands (25 kHz steps, shared with military users using FM and P25 digital in 12.5 kHz/25 kHz steps). 

I know the Air National Guard in my area uses 140 MHz and 141 MHz freqs (in AM mode) in addition to the usual UHF band frequencies, plus a couple FM tactical band channels (namely 38.500 MHz, 38.550 MHz and 49.725 MHz, I presume there are others I don’t know about) for air to air chatter.  The National Guard also appear to use over a dozen different repeated frequencies in the 148 to 150.8 MHz range for tactical comms, only instead of AM or FM voice, they use encrypted P25 digital voice (12.5 kHz channel steps). 

Oh, also 282.800 MHz - aka “Hard Luck” - which is also the search and rescue/survival radio alternate frequency to 243.000 MHz.  I imagine use of 282.8 MHz for air to air chat is frowned upon, but yes, you’ve got some hard luck if you have to use your survival radio....

I don’t know how many scanner channels you have to work with Josh, but here’s another “button” list for the USAF, apparently used for “auxiliary” purposes, such as air to air chat maybe.

265.500 MHz - “Button 1”
266.600 MHz - “Button 2”
267.600 MHz - “Button 3”
268.600 MHz - “Button 4”
269.900 MHz - “Button 5”
270.100 MHz - “Button 6”
271.600 MHz - “Button 7”
272.700 MHz - “Button 8”
273.500 MHz - “Button 9”
274.800 MHz - “Button 10”
275.800 MHz - “Button 11”
276.400 MHz - “Button 12”
277.200 MHz - “Button 13”
278.400 MHz - “Button 14”
279.400 MHz - “Button 15”
280.500 MHz - “Button 16”
281.200 MHz - “Button 17”
282.800 MHz - “Button 18”
283.000 MHz - “Button 19”
284.200 MHz - “Button 20”

If you don't mind me asking, what receiver(s) and antenna setup do you use for monitoring 225-400 MHz? 
Title: Re: UHF mil air
Post by: Josh on July 18, 2019, 2251 UTC
Right now just a Uniden 9000XLT as the rx, and a Comet or Diamond multiband mobile vertical hanging in the window.

The antenna has designed resonance in the 220 band, I suppose that's close enough to mil air for government work.

In the works is a disconey/lna/hi pass and fmbc filter up 30ft olr so, and then the sdrs will be brought into play.
Title: Re: UHF mil air
Post by: R4002 on July 19, 2019, 1553 UTC
The multiband vertical probably resonates pretty well in many sections of the 225-400 MHz band, presuming its designed for 2 meters in addition to 1.25 meters.  146 MHz x2 = 292 MHz. 

Discone = win.  That 30 foot increase in elevation will make a real difference too.  I expect your receive capabilities to be significantly increased.  I bet you'll be able to hear a low more VHF/UHF activity in general (30-512 MHz).  Maybe lowband isn't used very often in your area for public safety/business radio stuff, but its still used for military comms.  Presuming the disconey you're putting up is the 25-1300 MHz type, you might be able to hear FM milcom stuff in addition to 225-400 MHz, 137-144 MHz and 148-150.775 MHz. 

Also the SDRs will help a lot.  The VHF low/VHF mid band military activity seems to center around the following bands:

30.000 to 30.600
32.000 to 33.000
34.000 to 35.000 - including 34.900, the National Guard disaster relief common freq
36.000 to 37.000
38.000 to 39.000
40.000 to 42.000 - including 40.500, the VHF-FM version of 121.5/243.0
46.600 to 47.000
49.600 to 50.000

More frequencies to check, although I'm sure most milair comms are in the 225-400 UHF band, with the 137-144/148-150.8 VHF bands coming in second.

Expect a lot of ground support ops to employ "cigars";
SINCGARS uses 25 kHz channels in the very high frequency (VHF) FM band, from 30.000 to 87.975 megahertz (MHz). It has single-frequency and frequency hopping modes. The frequency-hopping mode hops 111 times a second.

From what I've read on other monitors' logs and from my own VHF low band DXing and monitoring, there's a large amount of ground-to-ground tactical comms using single-frequency aka single channel or SC mode, at least in the CONUS.  The military tactical FM band is the de facto world standard for tactical military comms (even Chinese tanks exported to African militaries come with a 30.000 MHz to 79.975 MHz or 20.000 MHz to 49.975 MHz radio installed!).  Seems like the former combloc countries favor slightly lower frequencies (20-50 MHz or 26-70 MHz or similar instead of 30-88 MHz, although it appears current Russian radios do 30.000 MHz to 107.975 MHz similar ranges).   

Milair comms in my area have been heard on the usual 46.750 MHz, 46.850 MHz and 49.725 MHz frequencies.   When I was still in the Civil Air Patrol I did a SAR exercise at one of the local-ish Army bases and there were signs on base for "FM" frequencies to reach medevac, range control, etc.  I remember 38.500 MHz was one of them, along with 30.150 MHz (I believe) and 38.550 MHz.  38.500 FM was apparently the primary on base Fox Mike frequency for air-to-ground coordination.  It would seem that FH / frequency hopping mode is reserved for electronically hostile situations/locations.  Use of the frequency hopping mode in the US would at the very least require coordination of the hopset frequencies to avoid interference with civilian users of the 30-88 MHz range.   

I did some research, it appears that 38.50 MHz FM (listed as FM 38.5 A/G USE) is still in use for air-to-ground comms at Fort AP Hill, as well as 241.000 MHz AM and the usual 126.200 MHz AM VHF frequency.  Instead of calling 30-88 MHz "VHF" its referred to as "FM" since "VHF" is 108-150 MHz and "UHF" is 225-400 MHz.

Their own private space repeaters! 

Given the proliferation of open-banded 1.25 meter/222 MHz gear (and gear for similar 200 MHz ranges, i.e. the 245 MHz VHF CB band in Thailand), because of that a lot of these Chinese rigs will do 220-270 MHz or something like that after modification, and still others that do 350 MHz to 390 MHz or 350 MHz to 400 MHz.  Apparently the 245 MHz band is extremely popular (80 channels, 245.0000 MHz to 245.9875 MHz, straight 12.5 kHz channel steps) in southeast Asia.  Like India and other places, there's weird use of the 225-400 MHz band for land mobile systems in addition to military aircraft. 

India has several land mobile bands in the 338-340 MHz band (paired with 348-350 MHz, 12.5 kHz channel steps with 6.25 kHz offsets, so frequencies are 338.00625 MHz, 338.01875 MHz, 338.03125 MHz etc.), a short-range FRS or PMR446-like personal radio service from 350.225 MHz to 350.400 MHz (in 12.5 kHz steps) and an additional land mobile allocation from 367 MHz to 400 MHz. 

Japan has another FRS like personal radio service from 348.5625 MHz to 348.8000 MHz (also 12.5 kHz channel steps and 1 watt power output), and the Philippines have their Short Range Radio Service or SRRS at 325 MHz (325.0 MHz to 325.4875 MHz in 12.5 kHz steps with 2.5 watt output power limits). 

245 MHz - 246 MHz, 325 MHz - 325.5 MHz, 338-340 MHz, 348-350 MHz and 367-400 MHz (I know the 380-400 MHz is heavily used in the United States and Europe for trunking systems, TETRA and similar technologies in Europe and elsewhere, Project 25 in the USA for military use).  Altogether that's 38.5 MHz of spectrum within 225-400 MHz allocated to land mobile services.  I'm sure there are other users in other parts of the world I'm not aware of.   

Regardless, those are a lot of potential signals that UHF milsats could accidentally retransmit - not including bootleg or pirate users operating out of band using modified gear.
