Khabarovsk ACC is quite busy on 6692 kHz and often heard during the late night and overnight hours here in California. While most communications on this RDARA frequency are in Russian, I have heard English used when talking with American planes. Nevertheless it’s something different to monitor.

Here is a recording of radio traffic monitored on 6692.

Earlier today on 11175 kHz Andrews came up and broadcast an interesting message: “Internal emergency. Station is securing operations”

RIMPAC 2010

Rim of the Pacific Exercise (RIMPAC) is the world’s largest international maritime exercise. This large-scale biennial exercise is designed to increase mutual cooperation and enhance the tactical capabilities of participating nations in various aspects of maritime operations at sea.

Listed below are some frequencies and recordings for RIMPAC 2010:


6693.1 – Mad Fox 44 and Japan Navy 88 w/ Blue Light.


13224.1 – Redhook 37 w/ Miniature (TSC Kaneohe Bay, HI)


13224.1 – Lone Eagle 61 and Demon 51 w/ Miniature.


13231 – Aircraft 778 w/ Unclouded (TSC Kadena, Japan)

13224.1 USB at 0300z with ongoing comms between Dragon Claw 19 (P-3C) and Miniature (US Navy TSCC at MCAS Kanoehe Bay, Hawaii). Both stations have excellent signals into California this evening.

While most of the communications remain on VHF, there have been a few reports of activity on HF as well. Several people have reported hearing phone patches and fishermen discussing the BP oil spill on 8650 USB.

Another frequency to keep plugged in is 5320 USB. This is used by the US Coast Guard and was quite active last night and this morning. Reception here in California wasn’t all that great, but I did manage to snag a little audio.

On June 12th at 0055 UTC an M-class solar flare from Sunspot 1081 generated a solar radio burst. I happened to be recording at the time and have posted the audio. Note the rapid increase in noise levels.

Additional info about solar events can be found at SpaceWeather.com

11306 kHz (USB mode) is an excellent frequency to monitor if your interested in hearing Boeing test and delivery flights. Aircraft typically come up to conduct HF radio and selcal checks with Boeing Seattle. Most flights use Boeing ### for their callsigns, however registrations have been noted on delivery flights.

The Boeing Test Flights Blog is an excellent resource that provides additional information about recent flight activity and FlightAware can be used to find out when aircraft are flying.

I’ve even logged the Boeing 787 Dreamliner up on this net.

Back in March I ran across some comms between NASA 817 and Gander Radio on 8891 kHz. The NASA callsign sparked my interest, along with the fact this aircraft was flying at 1,500ft over the north pole, so I headed to Google and learned NASA 817 was a McDonnell Douglas DC-8-70 taking part in the the Spring 2010 IceBridge Mission. To learn more about IceBridge 2010 see the following links.

Thankfully my recorder was operational, so I’m making the audio available for your listening pleasure. Pretty exciting to catch this aircraft during a totally random monitoring session just before local sunrise.

Stumbled across some OM’s with a very odd sounding dialect on 8225 kHz. I’m guessing they are fishermen. Any idea what language this could be?

Wednesday evening I stumbled across some type of military tracking net on 6735 kHz USB. One of the players identifies as Mojo, however the other station I’m not able to make out.
