This can also mess with CHIRP’s ability to communicate w/ the radio. It took me a while to figure out wtf was wrong with my intermittent transmissions, works great now. The fix in the video (recapped below) worked great for my radios which all exhibited the problem, with no casualties or negative side effects. The fix allowed the mic plug to to stay properly seated in the jack, and now works perfectly reliably without having to hold it in like was always needed before. Fix synopsis- I had been having annoying and persistent problems with the microphone plug slightly popping out and making for an unreliable, intermittent connection due to the odd plastic gasket that was not really flush with the jack port mouth, making the plug stand proud a couple mm, just enough to make the contact intermittent. After “spot facing“ the jack ports by hand with a 3/16“ drill bit to the depth of the pin bases on the microphone plug (3/32“ or 2 or 3 mm), the plugs now drop all the way through the gasket and into the jack ports, and happily my intermitent connection is no longer a problem. Also shown is an exploration of mic internals that does nothing except perhaps to show just how randomly assembled these external mics (and my trouble shooting skills) really are... :/ Baofengs are what Harbor Freight would sell if they sold ham radios. p.s. After posting the video I noticed that the bridge I soldered on the unsuccessful fix was labeled R9, so I went back and measured the “R9“ on the unmodified mic and the DMM read zero ohms- so go figure, it was just a solder bridge after all. In the meantime, the R1 pads looked to host an actual surface mount part so I didn’t think to measure it for low resistance, but if I take that damn mic apart even one more time i think it will spontaneously combust. Do we have any aspiring researchers who are willing to take one for the team? Given that I only had a sample size of two I bet there are constellations of internally misshapen Baofeng mics out there waiting to be outed...
