Thanks for the info.
Just for me to understand. Would it be difficult to generate APSR AFSK on the phone? I think APRSdroid does that but only at 1200 and 9600 baud.
As far as I know there are 300 baud HF gateways already out there.
It feels like an additional layer of dependency with the extra protocol and proprietary software for this gateway? Maybe the RBN skimmers (that are already all over the globe) could monitor also for HF APRS packets (or even a “new” or existing protocoll for messaging)?
But maybe I don’t see the full picture yet.
