FWIW the FT-51R has memory tune as well as full duplex, ...

And another thing the FT51R has is DTMF Text Messaging. This is compatible with the TH-78 as well.

There are dozens of thousands of these radios out there, and we hope to integrate their TEXT Messaging capabilties into the global D7 and other APRS text messaging and Email system as part of the Universal Ham Radio Text Messaging System.

The goal is text messaging by callsign alone, between any hams, anywhere, anytime, using any device. see www.aprs.org/aprs-messaging.html

All we need is a little software as a gateway. ... So we are looking for an idle programmer...
