5690 JSDF Comms?

February 21, 2011 in hf | No comments

I have been hearing Japanese comms on 5690 USB lately. Last night I monitored what sounded like JJN6 wkg 1BM giving weather conditions for Nagasaki. I have also noticed that the stations occasionally exchange what sounds like RTTY data in between voice comms. The frequency can be heard from California most nights between 0800z and 1200z.

Welcome fellow radio monitors and enthusiasts! Here you will find my reception logs and audio recordings for HF and SATCOM (with a focus on aviation and military) along with other interesting and odd things that have been monitored over the airwaves.

The majority of the logs and audio clips posted here have been monitored directly from my location in Southern California. I also share intercepts from online SDRs. They will be tagged with KiwiSDR to help identify.

My primary HF setup is the WinRadio G31DDC paired with magnetic loops such as the Wellbrook ALA1530. For UHF SATCOM, antennas used are the Trivec Avant AV-2011, AV-2055 and AV-2095.

If you would like to follow me on X my handle is @xiralos.
