6834.0 khz USB @ 0115z Feb 10, 2011

Extremely active right now. I'm fighting the conditions right now so it's hard to make out all of the parties but I've heard at least three.

Sounds like they've moved to 4703.0 USB now.. FYI.

...and they are back to 6834.0 USB.

Sounds like the same players across the board.

4703.0 USB
6834.0 USB
11190.0 USB

One of the longest set of USN Exercises I've heard in a while.

Yeah, I am not 100% sure 11190 is the same stuff, but I would be glad to be wrong. Keep in mind all I am hearing right now is generic call signs, Golf, Tango, Kilo, etc. Those are going to be the same on any USN and many USAF nets and excersizes. On 11190 the other day I was hearing those plus some unique calls, not yet heard on 2252, 4703, 6834.

Also up on 2252 right now.

There was a 5 MHz freq the other day, but I can't find my notes on it.

T!

(edit) Another reason I say I am not 100% on the 11190 being part of this op, the other day a Utah listener reported hearing some of the same callsigns on UHF working tankers, when the 11190 freq mentioned that some units were Texaco.

During carrier exercise's I usually don't monitor the HF net's.
One day last week I had a hit count of 1011 and that was just on my 396XT.
The first 9 day's after the carrier depart's Norfolk,VA, all the activity is off the SC and NC coast.
There is another 3 or 4 day's before this exercise ends.

I've heard plenty of military air comms on the UHF airband, but I've never heard military ops/exercises on the HF bands. What kind of traffic are you actually hearing? I'm very curious...

5295 USB was used last week. Definitely sounded like Navy comms, heard phrases such as "I'm sitting on a surface hostile for track 3052", "put friendly callsign Golf in timber", "I have a friendly unit in that gator". Signal faded out a couple hours before local sunrise, so the east coast is a good probability.

A battle group or a carrier task group will cover many, many, miles of ocean. As such VHF and UHF cannot be used because it is common for units of the group to be beyond the horizon. HF works well for this, and generally speaking lower HF works best. Sat works well also, but there are various reasons to continue to use HF.

A BG will typically have multiple HF nets running simultaneously, although some might be more active than others. Normally each net has a different task, one might be surface combat, one might be anti submarine warfare, one might be anti air warfare, one might be electronic warfare, etc, etc. Each unit in the BG will have a generic ID on the net, such as Kilo or Charlie, you will not hear ships names, although you will sometimes hear ships callsigns (such as Alpha Romeo, different from the generic callsigns). Each net will have a net control, net control can be any unit in the BG, not just the “big” ship, it can even be an airborne unit. Net control can change at times, and the new net control assumes the net control callsign, not using its own generic during that period. By the same token the former net control reverts to its generic call.

Exactly what you hear will depend on what net you are monitoring. For an AAW net you will hear a lot of target call outs, air targets that are being tracked, assessed, and quite possibly intercepted or engaged. For a surface warfare net you will hear surface targets getting the same treatment, track, ID, assess threat level, assign target, as needed. For EW nets the same with a twist, they might be trying to correlate the radar tracks with radar emissions. Each net will typically have a top of the hour situation report, “SITREP”. On a slow day or during slow times this might be the only traffic you hear on the net, so this is a good time to find unknown nets.

During exercises like this past couple weeks you will hear “peaks” in the traffic, a net might be completely quite for hours and then become very active for a short period during the simulated event.

Last night’s was very active and entertaining. It was obviously an AAW net simulating being in international waters but near a country of questionable status (this was probably the "strait transit" portion of the EX). It became clear the net control and BG in general was having an issue with unknown aircraft entering its controlled airspace. At one point an “intruder” came up on the net (part of the exercise), the intruder identified himself as an air controller directing traffic for the questionable country. There ensued a period of time were the BG net control and the foreign controller “discussed” the airspace and control of it, lines like “we are a United States military force conducting peaceful operations in international waters” and “you are endangering our air traffic” were thrown around (maybe not the exact words, I am at work and going form memory, but words similar to those). It got pretty heated at one point. This was also probably intentional on the part of the event planners, to force the BG net to respond.

A bit later another intruder came up on the net (almost certainly part of the EX) and tried to assume the role of net control. This caused a bit of consternation and lots of authenticating, with loss of net control by the unit who originally had it, and the net shifted frequency to 4703 to clear it all up. Yeah, they got a little squirrely in there, but they did get it cleared.

This EX has been going on a bit longer than standard, in fact it has been years since I heard an EX go this long. Last night was very eventful. Naturally, I do not know, but would not be surprised if that might have been the culminating event of the EX, that was kind of the impression I got. Later today and this evening might tell better, but we could be done with this event.

T!
