No one seems to have answered the OP's query. Yes, there are varying
degrees of support within the amateur radio community for doing actual
public good with the technology but that's a separate problem.
The short answer is no, the various software packages for Android,

How far is the distance being covered, and in what kind of terrain (flat
plains, hills)? HAM might not even be necessary if it's fairly close
(relatively speaking). GMRS radios can cover several miles. Other
small/cheap handhelds can cover a couple of miles in ideal conditions.

but the speeds are very low, from 31,25 baud to 64bps for the
traditional modes.

Your APRS idea is interesting and I only know it from the positioning side,
not from passing any text, so you may want to continue looking into it. I do
not know that APRS is currently passing any traffic other than positions, at
least as used in the US. I also do not know whether it's used

Thanks, Bernard for the info on APRS. I am out of date as I don't use it.
You are especially right that here in the US it's easy to get a Technician
license, which is the entry-level amateur license issued by the FCC. It takes
maybe 3 hours of study and a 30-minute test. I'd guess you have

Since HAM (amateur radio) is real radio, not phone, an Android app wouldn't
use it directly. The app might -control- an amateur radio remotely, and there
is software available to do this. However, I'm not sure what benefit it would
bring to this project.
In the US, amateur radio operators must
