Looking through the message.c code:


If the station has never been heard: 
   send to all ports, RF and otherwise
Else If the station has been heard on RF in the last hour:  
  send to the RF port on which the station was heard.
Else If the station has only been heard on the net *and* there is an 
        internet port with transmit enabled:
  send to all internet ports with transmit enabled
otherwise:
  transmit to all active ports


That is, a message will be transmitted to RF IF:  the station has never been 
heard, has been heard on RF in the last hour, or there are no active internet 
ports with transmit enabled.

If you are hearing a station only on the net and want to try to contact it
via RF, just disable transmit on the APRS-IS ports for a while.  No need to
shut down the interface completely.
