Hey,
I used to tune these when I worked as a tech for a public safety agency. Unfortunately, you have to take them apart. There was a battery connector plate that screwed on to the bottom casting to slide on the external powered (Fake Battery). There was a rear screw on plate (looks like a partial rear cover) behind the radio for the RF connector. Then, there was a multi-colored short cable (10 Pins?) that connected the two internal boards together so that you could actually get to the Oscillator pot. The first two I can probably make out of some beat up covers. Anyone remember or have a part number for the cable? Probably no longer exists, I'll likely have to make that too.
Then again, anyone found a better way or method, or made a better (Tuning Jig) for these? Appreciated Greatly!
