'Might be' the internal adjustment? I have fixed at least two 2096's and several pro 96's. If I recall correctly while scanning, press MAN and it should be on the control channel frequency. If you hear stuttering noise, likely needs adjustment.
Need to use a very small screwdriver and I have found generally about a 5% counter clockwise adjustment of the pro 2096's VR3 will suffice but your adjustment may vary.

Wile very annoying, you would adjust till the sound gets loudest and clearest.
