Hi all,

I did the internal GPS mod to my radio over the weekend and it's working great. The one issue I've discovered is that the GPS module does not power down with the radio. I'm currently using a point on the top left of the display board labelled VCC5 (see attached picture.... not my pic, just for reference as it's the only one I could find). Does anyone have an alternate switched source they could recommend? Otherwise I might just power the module from the USB port so it only powers up if the scanner is plugged in.

What gps module did you use? I am getting a new to me SDS100, it's in the mail and I am exploring doing this. Yes, I can micro solder. Sorry, I have no current answer to finding a switched vcc.

I used this module...
Geekstory BN-220 Dual GPS Glonass Module Navigation TTL Level 9600bps + GPS Passive Antenna for Arduino Raspberry Pi Pixhawk F3 CC3D Betaflight F4 Flight Control

Paired with one of these..
10Pcs Mini RS232 to TTL Converter Module Board Adapter MAX3232 120kbps 3-5V RS232 Serial Port Conversion Module, for Arduino MAX3232 Adapter Module Board

It's a little slow to get it's initial lock (usually 3-5 minutes) but works great after that. As for the power issue I ended up installing a little micro slider switch in beside the USB ports to manually control the GPS power. Acceptable solution for me.
