Update - Using APRSdroid with the Kenwood TM-D710 via Bluetooth

radio

Somehow I managed to kill the Bluetooth module I was using (reverse polarity maybe?) and of course couldn’t find another - I’m surprised there isn’t demand for such a module, maybe a project for another time.

Anyway, took a slightly different approach this time. Used a standard HC-05 type module and mounted it in the head. Wired up to some +5v I found and connected to the input side of the RS-232 driver included in the radio head (connected to the 2.5mm socket).

Works well, only downside that comes to mind is that the Bluetooth module is powered on all of the time as the supply to regulator appears to be unswitched.
