**** Due to changes in Baofeng manufacturing practices, please trace the internal wiring of your speaker/mic****
OK, now that the disclaimer is done, I have, with the help of CJ, been testing the internal wiring of the ubiquitous Baofeng Speaker/Mic. Many members are planning on using this speaker/mic for their MPET projects. I believe the accompanying wiring diagram can be used to successfully make the appropriate connections. As of this posting, this still needs to be tested, but the research looks sound. If someone is at the point of making these connections, and is willing to test them, please let me know.
