KE5RS Dialer is a handy 16-button DTMF keypad that lets you send DTMF tones through your sound card. It is perfect for those without DTMF microphones, as it uses the RTS on the serial Com2 port to automatically key the radio. It is especially useful if you are already set up with SSTV or PSK-31 using the RTS on Com2.
