Micro-DTMF Touch Tone Receiver/Decoder 
The Micro-DTMF Receiver/Decoder is an integrated programmable VHF receiver and DTMF touch tone decoder
designed for remote control applications. The receiver may be set to any 2 meter
amateur radio frequency (in 5 KHZ channel steps) via a terminal program and
a 3/32" (2.5mm) three conductor plug programming cable.
The decoder will decode all standard DTMF touchtones, and set the corresponding output
high momentarily during detection of the tone. The Micro-DTMF operates on 7-15V and draws about 30 mA.
Micro-DTMF - $160

MT-AIO Programming Cable - $15
