Cool Red River call sign heard back in the early 90's.

I remember this call sign "Red River" being used often in the early 1990's. Another like it was "Red Cliff" used in the late 1980's.
Its doubtful anyone would know the location unless your receiver frontend was swamped by the signal for knowing it to be in the area. These aircraft HF signals can be strong from thousands of mile out depending on day to day RF conditions on the bands.

Interesting "Red River" call sign is back again. Hum... Keep listening in. If the signal bends your S-meter its a good guess the transmission is darn close hi, hi. 11.175 Mhz has always been a fun one to listen into over the years. Back in the late 80's on occasion's some more than interesting radio traffic was in the clear when someone forgot to encrypt. SWL is much like fishing. Just when you think you won't catch a thing the Big One hits Martha! >))))()*> Keep fishing and let us all know.

Just remember nation first! Radio hobby #2, always. Loose lips and ships don't go together. Be C@@L.

I monitored an EAM's last night (06-30) at approximately 0200Z that was xmitted on 11175 and also the frequencies immediately below and above. Other EAM net frequencies 8992 15016 etc only indicated the EAM as being xmitted on that particular frequency. Found this to be somewhat unusual as I have not noted it previously. Screen pic below:

Been listening to 11175 KHz USB today and heard several EAM's with the call sign "Hoverbar". I wonder where "Hoverbar" is located? Didn't sound like he was on an aircraft, so I'm guessing he's a ground station. I thought they used to always use the call sign "Mainsail" when they were calling all stations. Maybe they've changed it to "Hoverbar".

The call sign you were hearing was Color Bar. The HFGCS ground stations, Andrews, Offutt etc now use "tactical " call signs most of the time, to identify themselves.

I was listening to military HF/SSB, local VHF/UHF & UHF SATCOM a lot in the 1980s & 1990s & don't remember hearing RED RIVER or RED CLIFF being used as static calls.

First you state that HF aircraft signals can be strong from thousands of miles away, but then you comment about how if a (HF) signal "bends your S-meter" being a good indication the transmitter is "darn close" is wrong. I remember plenty of times when living in both Michigan & the Washington DC area, Radio Havana Cuba would 'pin' the S-meter (60+dB over S-9) on my Kenwood R-5000. Does that mean they had remote transmit sites in SE Michigan & the DC area? For groundwave HF, basically by the time your signal meter is pegged, you ought to pretty much be able to see the transmit antenna.

RED RIVER is the static callword for the 8th AF Air Operations Center at Barksdale AFB
8th Air Force - 608th AOC & it's not classified info.

It has minimal OPSEC value, since there's an actual river called Red River running near the base, and a base chow hall is called the Red River Dining Center.

Back in the day, as a SAC base & later SAC's 8th AF HQ, Barksdale did have a somewhat major presence on HF, with separate HF transmit & receive annexes but these days, I think it's likely that the AOC's day to day, organic HF capability is one transceiver & one or two antennas on-base, of course with the ability to remotely access other US Strategic Command, USAF Global Strike Command & DOD HF nets around the world.

Anyone ever heard the call sign CANDYMAN? They read several EAMs 30 characters. I looked through all my lists. No luck. REDRIVER is pretty active today also. MIke

A flurry of activity on 11175, 15016, and 8992. Motor, Bright 1-0, Skymaster, Composer, Shorthand, and four others in the mud; two females two males. As we all are, I'm ignorant to what's going on but I haven't heard this much run-on activity in a long time. Several EAMs and a half-dozen 4-group messages so far. Been monitoring for the last two hours.
Adding three more to the list-Bright 0-9, Motorist, Allowance.

Good question as I only know of 4724, 6397, 8992, 11175, 11220, 11244, and 15016kHz. You caught some unusual ones there. How'd you do it-SDR? BTW the activity seems to have gone way down now.

Yes. Was looking at pirate radio 6500-7000 KHz on SDR. USAF freq activity down now here too so guess it was just exercise.
If you've never heard HF pirates before, give a listen on 6925-6975 most evenings, usually USB or AM.
6940KHz USB active right now. "Clever Name Radio" is on. Playing a relay of "Cool AM radio". A station from Netherlands.

There's been a lot of long-winded EAMs last couple days up to 96 characters (my observations). Also activity on 11232 but haven't got a read on that yet.

I was just thinking last night how they have really been active. I have scanner to listen too the localPD/FD with 311 popped in. I first noticed this past Sunday how they have been going so much.

Default 8.992 KHz.

About every half hour I am hearing a transmission sending letters by voice. The audio sounds like the gain is set way too high and causing distortion and sort of a room echo effect. It is happening about 14 past the hour and about 44 past the hour.

The title should be 8.992 MHz.

Yeah you guys are catching end of Global Thunder 18 on HF.
Been busy last 5 days or so.
Your echo is most likely you receiving multiple worldwide stations on same freq but slight time delay due to distances between broadcast stations.
USSTRATCOM works with allies during Global Thunder 18 > U.S. Strategic Command > News Article View
