Another possible APRS Message return path is to use very low power,
reliable WSPR links.
Although WSPR only communicates CALLSIGN and then GRID, and POWER in only
22 bits, we have already exploited simple FIVE DIGIT communications on our
next QIKCOM- satellite (awaiting launch). http://aprs.org/qikcom-2.html
Via QIKCOM-2, any user with only a DTMF Ham Radio HT can communicate into
the global APRS system using even an ICOM-2AT that is 40 years old. Using
4 digit codes we can communicate:
· Grid position
· Any of the 43 ARRL Radiograms
· Including a 2 digit modifier in some messages with variables
· Such as #30 which can say any of the 14 Maritime emergency codes
· And there are still thousands of codes remaining in the 22 bit
See now we are proposing to experiment with a parallel WSPR return path for
this OUTNET Ham Radio OUTERNET experiment.
So, if you are playing with WSPR in addition to your AMSAT interests, let

OUTERNET is a free worldwide Geostationary Satellite downlink system
designed to bring content to remote areas all over the globe. They have
six geostationary birds covering the entire globe EVERYWHERE. All you need
is a small 18” (or 36” in some very remote areas) to receive content via
your own home-made receiver based on a TV dongle and Rasberry Pi.
Is there anyone on AMSAT-bb that is already receiving this content? We’d
like to hear about how easy it is to set up a receiver.
We have some ideas on how this can be used to augment Ham radio in our
Emergency Response and remote operations missions. See
