I have been able to get it functioning properly today. 

I had to do some more flying wires. Turns out I really messed up this first board. I guess that is why all good projects have multiple versions.  It will do a simple repeater of what comes in the input radio to the output module's freq. For now I have been using one of the 70cm Unprotected Shared Pairs.  

It is currently just making the PTT on the TX Radio follow the Audio On signal of the RX Radio. Originally I wanted to use an Interrupt to do this on the rising and falling edge but for some reason the interrupt refuses to fire. I am not totally sure why that is either. 

It currently has no way to timeout or identify itself.  (I was happy enough to even getting it repeating for now.) Next set it to try and make it ident at all then I will work on the timeout features. 

Once I get all that working is when I will start looking into making a web page to allow you to configure it over the network.
