Hi Andy! Finally got ahold of a VX-8DR and like some users, desire to get GPS functioning. So far, I got a simply straight wired GPS for testing (no altitude received— Adafruit Ultimate GPS), but not yet gone done the path of programming an Arduino Uno and connecting all the bits to passively (?) retranslate NMEA sentences to Yaesu-friendly strings (that’s what we’re after, right?) Had you ever considered just adding Bluetooth (3.3V with an audio DSP; found an RN52 that may function that way) instead (to allow for more modern headsets to connect— and if I had to guess it’s simply wiring up the audio (R speaker/mic?) to the VX-8DR pins? If not, had you considered not putting in any switches and streamlining the whole lot? Thanks, and thanks so much for the detailed info!

Hi Jack, no never thought about BT for the VX-8. I didn’t go any further than this on mine and eventually swapped the VX8 for a Kenwood TH-D72.
