This, on the other hand, does have potential to be fun, depending on what functions DTMF in the hands of the user can command. For example if you could ask for a report of some satellite parameters, or if you sent your callsign in dtmf and QSL comes down by voice, maybe even send predefined messages that get echoed by voice synthesis. But if you send a call and grid by dtmf and it just gets sent back via AX-25, so a ham has to check ariss.net to see if they were echoed and received by a sat gate, it won't get much use.
