UV3D APRS working!

My problem turned out to be power related. Whenever the TT3 would transmit, the voltage would drop to around 4.7v and it would reset. I added a LM7805 with 4 AA batteries, and it is working reliably now. I also moved it from the breadboard to a circuit board so I can test it on the highway.
