Hope this message will find you well.
I just monitored in Porto Alegre, Brazil, this signal on 9460 kHz. Searching on Internet I found that it’s the same frequency where the Russian MR-102 Baklan radar is operating. But it could be a weather fax. Do you have any clue?
Please, check attachment for the audio clip. Thank you in advance.
Thank you for sharing this, Carols. To my ear it does sound like some sort of slow-scan digital mode like weather fax, but I’ll leave it up to the SWLing Post community to help identify.
Post readers: please comment if you can ID this signal for Carlos.
UPDATE: Nils Schiffhauer found the answer. The signal is a weather fax transmission most liekly from Wellington, NZ.
Just to remove any doubt at all, here is the segment from the article decoded ( it was off frequency & very noisy, but you can see that it is a weather chart nevertheless 🙂 )

Danke again for your usual kindness, Neil, you’re definitely an expert.
Thank you all for the comments.
I got a confirmation from Kevin Alder, MetService Manager Meteorological Data Services.
It was originated from their marine radio broadcast service at Auckland Airport.
Hi it looks like weather fax, however there’s this link to qee too :

Good luck !

One way is to use a Kiwi SDR and use the fax setting. Would work if the tuner can receive the signal …
Many, many years ago the NZ Met service decided to use 9410 kHz which was a long standing frequency used by the BBC World Service. The fax transmissions were soon moved.
no expert, but it doesn’t “sound” like a regular wefax

my suggestion is to use “artemis”

to try identifying the signal, and if it gives no results, try contacting the sigid wiki people
