I have a Maestro attached to my 6500, and I love using the VFO A knob on the Maestro. It is so well balanced that it makes spinning it very easy; especially when you are in a rush to get up or down the band collecting contacts. However I noticed that when I do this (spin the knob), I hear the radio clicking inside the unit. My question is: am I potentially doing damage to the radio by spinning the knob like this? I know I can double tap the screen and accomplish the same thing, but I prefer the knob. However I won't spin it any longer if this could potentially have a damaging effect. Does anyone know for sure?
