[liberationtech] Can HAM radio be used for communication between health workers in rural areas with no cell connectivity?

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
responses at:

The Android HAM option is software control of an external HAM receiver or a
web-site that relays HAM radio groups. It is not an actual radio solution
and will require the regular cellular data network to function - which
defeats the purpose of what you require.

Good luck, Cheers, -Ali
