It's a simple PIC based transmitter board for the general TX modules SFE sells. Nothing special, but just in case I missed something I'd love someone to point it out.
One thing I'd like a comment on, I have this circuit on a breadboard but it won't run when I apply power. I have to connect the PICKit2 debugger to get the code to execute. I do have MCLR pulled high through a resistor, but I seem to be missing something. The breadboard is running on the internal oscillator, not the resonator shown.
Also, for Q1 I was thinking of using a 2N2222. I have a 2N3904 on the breadboard but I don't have any 2222's around. Any reason it won't work? I was going to order some 2222's for another project and would like to keep the part variety down.
