Hi all,
I just noticed today that recently the Outernet satellite information service just switched from K-band to L-band.
This allows for a much smaller patch antenna to receive the signal from Inmarsat, but at a lower bit rate (20 MB/day).
This is a free service, and can be received with low-cost hardware: Raspberry Pi 3, RTL-SDR, LNA, and patch antenna. All available from Amazon.
Apparently APRS is being rebroadcast, as well as weather satellite information.

They provide a VM that seems to work on the Mac, I just booted it, and it found the RTL_SDR dongle...

Andrew,

Instead of a Raspberry Pi, you can try the Virtual Machines, but dig in to the above to get started.

Have the plug and play system up and running. Pointing is very uncritical, and the 46 degree elevation nicely clears the trees.
After 3 hours, the only download is some APRS traffic. ;)

I was ready to buy the stuff and got too confused. So Scott, K4KDR wrote this nice summary: http://aprs.org/OUTNET/Scotts-description1.txt
I have a link to it on the APRS OUTNET page: http://aprs.org/outnet.html
BIG PICTURE: The bottom line is you build one of these boxes, take it anywhere in the world, and it receives the Outernlink downlink and creates a WiFi hot spot that any surrounding users in WiFi range can then access the downloaded files. In addition to Weather for example are the hourly APRS files showing all the Amateur Radio Satellite APRS downlink data.
And/or any APRS traffic that contains the word OUTNET in it. So anyone can send messages anywhere in the world to such users. Then they can use APRS on HF or satellites or whatever to reply back. Thus, a possible 2-way emergency response system.

Bob,
A couple of hours later, and I also have weather, some basic news, pictures, etc. Reminds me of the KO-23 pacsat days. Easy to check from my computer, but also my phone. Next step is to come up with a better and more waterproof mount than the two old textbooks I used.
Scott's collection is good. The basic information is there on the Outernet site, but badly scattered.

It seems like the Outernet folks may be ramping up the data feeds, so perhaps more content is to come.
I hope someday a service like this will be available from an AMSAT geostationary service.

I'm pretty confident that the guys at AMSAT-DL are capable of doing this much better on the upcoming EsHail'2 than what Outernet is currently doing on Inmarsat (unfortunately not worldwide coverage).
They already have in mind a "DVB-S beacon", which is a DVB-S signal that is broadcast from the ground station at Qatar and through the wideband Amateur transponder. They plan to put informational videos about Ham radio and Ham radio events on this signal. They could also include some data stream if there is enough interest.
What is more, if you have equipment to operate EsHail'2 on SSB, it's more or less easy to use either the narrowband transponder or the wideband transponder to transmit an Outernet-type signal through EsHail'2, so anyone can have a go with this.
Outernet uses 4200baud BPSK and half of the bitrate is spent for FEC. You can use a bit less bitrate to get a signal that will even pass through a conventional 2.7kHz SSB filter and you can use less bits for FEC to get increased data throughput (at the cost of a bit more SNR required).

Dani EA4GPZ.
