Title: UNID likely M89 @ 7065kHz 1930-2000 UTC
Post by: Asuyuka on January 28, 2012, 2020 UTC
Caught a morse code station using old noise transmission at prescribed frequency and times.  From research, with no prior audio samples of said station online at the moment, will assume its M89 for the time being.

Caught broadcast on recording, will decode it shortly.

Suggestion for future here.

When reporting these kinds of stations (really any utility station) it is best to include as much info as you can in the first post.  For example, others might have heard it and might be able to confirm it, or might be able to hear it the next day and confirm it.  Or, if it is not the station you think it is someone else might be able to assist in IDing it by knowing what was on the freq/time/day you heard.  But, without more description it is impossible to do this kind of confirmation/assistance.

The following is meant as helpful suggestion, and not a criticism of your post:

In general any mention of a station should have the frequency it was heard on.  By convention on HF frequency is generally indicated in kHz, but MHz also works.  So 6.930 MHz or 6930 kHz would either one work.

The time of the reception.  Nearly universally such time should be in UTC/GMT, but even local time is better than nothing.

Date or day of reception.  Some numbers stations transmit only once a week, or only on certain days.  For those kinds of stations a date (in UTC date, not local) can be a quick way to accredit the possibility it is what you think it is.

Mode of reception, USB/LSB/AM/etc.  Sometimes the difference between one station and another boils down to the transmission mode.

Message format.  Particularly with numbers stations format is a key.  Yes, I know you said you were going to decode it later, and so you might not know the format yet, but just saying this for completeness here.

T!

Thanks for the tips. :)

Still waiting for it to be decoded-- the recording is on my sister's iPod, and she hasn't pulled it off yet.

Pro quality equipment?  You bet.  :D
