Beware the link has changed: http://www.w1hkj.com/downloads/flamp/Amp.2.0.Specification.html "Amateur Multicast Protocol" Ah, ok, thanks, never heard about it. But instead, why not setting up a Hayes interface on top of fldigi modems, and then have an IP interface ? This way, we would have all the benefit of TCP/IP sockets without having to reinvent a protocol (Which is usually not a very simple task). Any new fldigi modem could then be chosen, and thanks to RFID, the receiver would automatically switch to the transmitter modem.
