Thanks to Ali-Reza for reposting Dr. Dey's reply.
If you are looking for lowest-cost short to medium range communications
using ham radio, Android phones are not the answer. You still need VHF
or UHF radio hardware.
There are at least 20 radio manufacturers in China that make small
variation
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,
iPhone, Blackberry etc.

They exist a lot of digital modes used by the amateur radio operators,
but the speeds are very low, from 31,25 baud to 64bps for the
traditional modes.
(PSK, MFSK, PACTOR, RTTY are mostly used, obviously for chatting, while
the APRS is mainly used for the identification and localization of a

Nice, Erich.
In a sense, radio waves are the -ultimate- in liberation, crossing national
boundaries in (single or multiple) bounds. That may be a subrosa reason
governments fight so hard to control them. That is clearly why some shortwave
broadcasts are jammed. It's why the amateur service was

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.

Dr. Dey,
It appears you let the list off the response to me. Likewise it appears you
have been dropped from the list discussion. You can see everyone's

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 I am out of date as I don't use it.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 somet

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

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.

Depends on what information you might be transmitting and the specific
laws of the local country/countries involved.
HAMs have to be licensed through the local countries licensing

Under US you could probably get away with allowing them to coordi
