First off, for anyone who does not know yet, the general freq for APRS on 2mtrs is 144.390, no tone needed.
Secondly, does anyone know if you can send messages from a phone connected using TCP, to an APRS radio on rf? Also are position reports from a phone propagated over rf at all when the TCP connection is used?
Second question first: No, position reports sent directly to the APRS-IS servers over the Internet don't get sent over the air.
First question is a little more difficult: I think if a gateway has heard from an RF station, and the gateway is configured to allow it, you can pass text messages from the Internet to RF. I've done it with Xastir in the past. If I remember correctly, you may have to manually route it to the gateway you want, although the article below says otherwise...http://aprsisce.wikidot.com/deleted:aprs-messenging-explained
