I had this on my SDR recording, possibly as early as 0142. Actually, something seems to pop up on 6930 now and then on the recordings. Always way down, just above the noise floor.
Bits of music now and then when the signal would briefly increase.
CYOT CW ID and then off at 0211. The ID was repeated, and it took a few tries, and the use of SSB and a narrow filter, to decipher it. The CW was on both sidebands, so I am sure it was transmitted by this station.
Also, I cannot stress this enough - without the CW I never would have been able to ID the station. It would be great if ops could send periodic CW IDs, as well as one at sign off. There's lots of software and probably even some websites to generate CW audio. Send it nice and slow, and repeat it a few times. It would really help us listeners ID stations under marginal conditions. And then you ops get more reports in return!
I noticed a carrier again on 6930 from about 0311-0342. Weaker this time, and no obvious audio.
