Nice large knob allows easy tuning ... too easy! Is there a feature like the top 3 hf manufacturers have to increase the rotation resistance on the large VFO Knob.

The only way it is even usable after setting your frequency is to press the LOCK button so you don't bump it and change the frequency.

Love the flex 6400M, All the knob sensitivities ... NOT SO MUCH :-)

Place a round felt or cloth washer behind the knob.

I agree. The VFO I could have lived with but the other knobs like mic and filters where too touchy. I thought it was just my radio but seems lots of people are saying the same.

I wonder if felt disc under the knobs would help?
