I'm currious.
How would one go about connecting the "external" battery to the Ranger. For a 5V "high" to be seen by the INIT input, you would have to have a closed loop, right?

I don't have the schematics with me.  If I remember right (James correct
me if I am wrong!) we are talking two different inputs.  The 5V INIT is
just the trigger signal from Handyboard, but the 5Vdc POWER for the
transmitter components comes on another line.  If I'm wrong, and they
*are* the same pin, then we need to design the 5v INIT signal from the
HB to trigger a solid state switch connecting our power pack to HB INIT.
