Hacking the uv3r

Proof of concept for re-flashing the uv3r. This firmware tunes to 145.525 and listens to a signal. When a strong signal is received it will play back 3 dtmf tones. Flashing the chip was accomplished with an arduino and only requires soldering 5 wires to direct pads on the radio. More information will be available on www.liorelazary.com.
