[aprssig] D710 GPS Port

[Scott Miller]

Bluetooth is nice for convenience (you're right about the complexity and 
development cost, though) but in a situation where you need reliability, 
I can't see adding more wireless links and batteries into the mix. 
Yeah, cables can be a hassle, but at least you can standardize 
connectors and fix things in the field.  In the middle of an emergency 
response is the last time you want to be worrying about device pairing, 
interference, and whether or not all of your peripheral batteries are 
going to hold a charge.
