6914 kHz Mystery Station

This weekend, I’ve noticed a station transmitting periodically on 6914 kHz. It will come on the air for a few minutes, then go off. All transmissions appear to be AM, with a variety of modes, such as CW (so MCW in this case), RTTY, and even some voice.

Last night I heard transmissions until the last one ended at 0136 UTC, when they stopped until 0745 UTC this morning. None were noted on the SDR recording during that time period.

When the transmissions restarted at 0745 UTC, they were extremely weak.

Here is an RTTY transmission (again, sent in AM mode) using 1000 Hz shift, 45 baud, with a center frequency of 1700 Hz, received at 2345 UTC 1 June 2013:

The signal was not the best, so there are some errors in the decoded text. Here is an Audio recording of the transmission.

Here is a CW transmission at 1358 UTC on 2 June 2013:
And the decoded text, thanks to Token for providing it:

Token has reported this station on both 6914 and 23146.5 kHz back in December 2012.

  2. Interesting. I heard what sound like a Hurricane Net there in ssb 15 June in timeframe mentioned by Chris for the 1 June data transmissions.

    They were discussing new manuals and protocol for their region , the Southeast USA for the upcoming Hurricane season.

    I wonder if they know about each other?
