    Getting the receiver out of the `city' is the greatest idea I have
heard of.  You can keep the transmitter anywhere.

   Sure, a rig with an RS232 control connection, with a pair of
modems as long as the remote modem returns to auto answer after
it is disconnected, so you can re-dial it, is possible.

   How are you going to get the audio both ways?

   If nothing else, you could power the rig up with the ring signal on the 
telephone line and keep it up with the OH LED of the modem.

   Is there a reason to not use a UHF link?
