COM volume knob has no tension

[jefish]

Unboxed my SV-COM again today, preparing to cut my panel for install, and noticed that the volume knob has no tension at all. The HDX knobs are clicky, the COM tune knobs are clicky, the Intercom knobs have a good bit of resistance, which is what I'd expect of any non-clicky knob. The COM volume, however... I think you could almost change the volume just by blowing on it. Normal?

Yes, normal. I was told you can slip a small oring over the shaft / below the knob and induce some friction. I just haven't tried it yet

It's been suggested, but since the knob has no set screw, the pressure of the o-ring pushes the knob to slide on the shaft, reducing the tension back to zero. Many folks have commented that their knobs are the same as mine, so it's "normal."
