What exactly is SafetyNET? I’ve never heard of it and cant seem to tie any google results to something that would be on Outernet.
I was able to get with outernet kit and http://www.tekmanoid.com/egc.shtml
Some interesting traffic can be seen there. I’m thinking about setting up a permanent receiver terminal for this, just for grins.
.BOGOSLOF VOLCANO AT 54N168W IS IN A STATE OF UNREST. MARINERS
TRAVELING IN THE VICINITY OF BOGOSLOF VOLCANO ARE URGED TO
EXO 30N E OF 140W AND 03.4S TO THE
EQUATOR E OF 120W
So this is alerts of bleep going seriously wrong. Volcano style or hijack at sea style? Ought to be in the feed.

Thanks everyone for all the info, I actually want to get a boat someday, SafetyNET seems like something a sailor should definitely be familiar with.
Good to know stuff like this if you are on the high seas…

It would be nice to get this feed on Outernet
What is the frequency of this signal? I do not find that on the websites that I searched.
Is it not available on the same satellite as Outernet is? What I locate refers to different Inmarsat
The Safety net stuff is not carried on AlphaSat (15.5 e ) which is the one we use for Outernet
It is on 1537.1 Mhz on the 64E satellite though… it has an elevation of about 3 degrees for me, ( and is behind the house) so I can’t see it…
HOWEVER - it is on HF ( technically MW) on 518Khz USB in Europe , transmitted in relay in 10 min timeslots by the nations around the coastline.
It is “navtext” and easy to decode with FLdigi and a USB SW receiver . - the main problem is you will only see stuff that is “local” ( depending upon what transmitters you can hear) weather warnings are sent on all transmitters as are “pan” calls.
You get the “bonus” of extended weather forecasts, too
Here is a video ( not mine) of someone doing it in 518Khz
Pity… I was thinking along the lines of receiving it on an Outernet system simultaneously with the
usual signal. When it is within the bandwidth covered by the RTL stick initial downconversion and
sampling, and there is enough CPU power, that would be doable. However, both the frequency and
the different satellite rule that out.
I’m receiving Aero successfully from Inmarsat I-4 F3 but cannot seem to find a frequency for SafetyNET.
Is there service from this bird or only from the ones over the Atlantic and Pacific?
Scroll down this page for the frequencies:
I’m getting it from Inmarsat 3F4 at 54.0W Western Atlantic coverage at 1537.7MHz, using the paper helical and SDRPlay, inside the house.
yes, I was disappointed to find it too ;(
I spent some time investigating every signal for a while there…
(edit again) I see that I was beaten to the link LOL!
Reoriented the patch antenna to 3F4 and the signal is fairly good. Just copied this

We are at approx 109 degrees west here in eastern Arizona and am somewhat surprised at the signal quality. Fortunately the best visibility from our valley is to the east. Tried the tekmanoid software but having an easier time with tdma-demo.
Thanks for the frequency info.

I often listen to the NAVTEX broadcasts on 8.416.5, 12.579, 16.806.5 kHz, which like the MW ones on 518 and 490 kHz are targeted to a particular region. There are also several other HF frequencies used, and here is a comprehensive list:
Fldigi is a good program, but for Navtex my personal favorite is YaND (Yet Another Navtex Decoder) which although designed for 518 and 490 kHz (includes logging, schedules, etc) is fine for HF freqs as well.
