New messages on 10405 kHz regarding arms embargo ops being conducted by NATO. The signal was heavily jammed but still able to hear what’s being said for the most part. This was recorded using a remote receiver in Switzerland. Special thanks goes out to the great folks on Utility DXers Forum for the heads up.

Lately there has been some exciting stuff monitored from the Mediterranean region out of Libya. One of them being the Commando Solo broadcasts from a Lockheed EC-130J aircraft c/s “Steel 74″operating in the region. Part of the mission has been to broadcast warning messages to the Libyan Navy advising sailors to leave their ships or face deadly consequences. Frequencies 6877 and 10405 kHz USB have been used over the past week.

Here’s a recording taken this morning via remote SDR in Germany.

With band conditions improving, I have been getting up early to catch stations from Asia and the Pacific. This morning I was listening to the Chinese numbers station (V26) transmitting on 7553 kHz in USB mode. I also heard them last week on 9153 kHz USB. The Enigma Control List shows 4283, 9054 and a few other frequencies V26 has been reported on. Best time to listen here on the west coast is between 1300 and 1400 Zulu.

Last night HAARP (High Frequency Active Auroral Research Program) was up on 3250 kHz and received very well here in California. It was the first time I have been able to watch it on the SDR waterfall and it was pretty interesting to say the least.

Here are 2 screenshots from HDSDR. (Click for larger view)

Below is an audio clip of what some of the HAARP tones sounded like.

The Vietnamese numbers station has returned on 10255 kHz USB. The station was first reported early last year on the IRC channel #wunclub and was active until September 2010. It can usually be monitored here on the west coast starting at 1600z. A well respected UTE monitor that goes by the handle “Token” has been following the Vietnamese station closely and has compiled a wealth of information on his website: VTN, the Vietnamese Numbers Station

For those interested, below is an audio clip from this morning’s broadcast.

Here are some high frequency audio recordings of radio traffic monitored after the Japan earthquake. Communications are in both Japanese and English.


5708 kHz USB Japanese Rescue aircraft. I believe the callsigns are Rescue 81 and Rescue 93. Talked about switching to frequency Papa 33 Sierra.


6640 kHz USB Hawaiian 457 wkg Hawaiian Dispatch in regards to earthquake status and conditions are Haneda International Airport. The Hawaiian Airlines dispatcher gives the flight a prepared statement to read to passengers.


6727 kHz USB Japan Maritime Self Defense Forces. Mostly weather for airports.


6751 kHz USB Many flights giving position reports around Tokyo and other areas along the coastline. Aircraft were most likely conducting recon flights and assessing damage from the tsunami.


6742 kHz USB This frequency had Japanese sounding aircraft and other related traffic. Also noticed some data bursts (or encryption) on a regular basis.

Hearing Japan Maritime Self-Defense Forces on 6751 kHz in USB mode. Both aircraft and ground stations very loud here in California. One aircraft gave position of 36.59N 140.53E putting them near the tsunami zone. More activity from Japan SDF on 6727, 5690 and 5693 kHz USB all related to earthquake. Japanese SAR traffic has also been logged on 5680 kHz USB.

nickcarr in #wunclub reports 6742 kHz USB is another frequency with station wkg Japanese sounding aircraft and on 6773 kHz USB heard frantic comms with some screaming. Tokyo MWARA traffic has been monitored on 6655 kHz USB. Vambo from #wunclub reports 6640 kHz USB busy with phone patch traffic for airliner diversions.

Here in California this morning, we have activity from Air Force Rescue 212 on 5711 kHz USB wkg Moffett Rescue. They have also been in comms with CAMSPAC on 5696 kHz USB. Activity related to tsunami threat in western USA.

I will post more frequencies as they are found. More Japanese earthquake related HF frequencies can be found on the Milcom Monitoring Post blog and the RadioReference Wiki.

March 17 update: Just logged Coast Guard 1701 up with Sector Honolulu and CAMSPAC Pt Reyes on 5696 kHz USB. Flight departed Barbers Point and en route to Yokota Air Base, Japan. I am also hearing Japanese activity on 4736 kHz USB with both voice and data modes.

March 16 update: I am currently hearing Japanese comms on 9034 kHz USB. The format sounds related to the activity on 6742 kHz.

March 12 update: Reception starting to pick up into Japan. Hearing activity on 5680 and 5708 kHz USB at this moment. (0852Z)

Bloodhound 300, Bloodhound 701, 401 and 442 wkg Surveillance on 8000 kHz USB this past Monday (2/21) coordinating vessel movements within a hazard area for a missile test off the coast of Southern California. The Arrow 2 missile defense system test is a joint exercise between the United States and Israel that intercepted and destroyed a simulated Iranian ballistic missile threat.

Around sunset the stations switched over to frequency 2781.5 kHz USB for the remainder of the exercise. It was definitely an exciting event to monitor!

Here is a recording of radio traffic monitored on 8000 kHz USB. In the clip you will hear aircraft passing details about several vessels, and trying to deal with a stubborn captain refusing to alter his course!
