Hi.

CF is 4346,0 kHz (FAX = FSK), 4344,1 kHz might (!) be the frequency you tuned your receiver to.... ::)

Hope this helps.

Hi.

Shift is 170 Hz, I guess you mean "Offset"...

As this is an FSK transmission the center frequency (CF) and window frequency (WF, or dial frequency DF) for this mode is both 8414,5 kHz - right between "mark" and "space". This is valid for ANY fsk mode on HF - RTTY, SITOR (including DSC), FAX, STANAG4481 etc.

What you are using as window frequency (WF) or dial frequency (DF) is depending on the decoder/modem you are using. Normally the offset for DSC is 1700 Hz (a.f.a.i.k. defined by ITU and IMO for the maritime mobile service on HF, including GMDSS). Same with NAVTEX on 490 and 518 kHz - that is the CF transmitted, despite the fact if it is modulated by a modem or directly by the transmitter.

On the other hand we have those PSK, OFDM, BPSK etc. modes where CF and WF are different (STANAG4285, MIL-STD 188-141, MIL-STD 188-110 etc.). The offset for S4285 for example is 1800 Hz so you have a WF/DF of let's say 3998,2 kHz and a CF of 4000,0 kHz.

Please be aware of this difference in modulation and demodulation of any frequency shift keying - from RTTY, SITOR-A/-B (and DSC), NAVTEX, STANAG4481, DPRK-FSK, AKKORD and so on.

Hope this helps.

Hi.

This is JOMOC Northwood - the military meteorological and oceanographic service of the british forces. Callsign GYA using the DHFCS transmiter sites.

Military One is the name of the programm they transmit and NOT the stations name.

Hope this helps.

Hi.

This looks a bit too much like DSC (SITOR-B) traffic on 8414,5 kHz, not 8412,5 kHz.

Could you please verify that?

Hope this helps.

Hi.

Sometimes it makes sense to have a look at -> www.priyom.org when coming across that kind of fast morse. Of course it could be something else but a numbers station but a quick look at their numbers schedule may resolve most of it.

Hi.

This was M12 with its Monday/Thursday schedule 2000/2020/2040 on 11109,0 / 10309,0 / 9209,0 kHz and ID 385 for September only. Frequencies will change in October.

Hope this helps.

Hi all.

Not really a numbers station but UTILITY.

@admin: Please move it to board UTILITY. Thanks.

Hi circuitmike.

A recording would be nice so all others can help you identify the signal.

Thanks in advance.

Hi Ken.


What does this repeated post mean?

I guess I should go listen....

Only getting to rise his number of posts with useless junk, I guess.  ;D
