The volume / on-off control knob on our Wouxun KG-UV3D radios has the most minute raised dot you can imagine to mark its orientation. Yes, it’s another subtle black-on-black control! See if you can spot the dot:

The radio lives in a small pack attached to the back of the seat frame: we turn it with a fingertip and adjust the volume by touch; the dot is just barely perceptible to my finger. Nevertheless, WIBNI (Would It Be Nice If) you could look at the knob from a distance and determine whether the radio was turned on?
A dab of typewriter (remember typewriters?) correction fluid later:

Not elegant and sure to wear off after a while, but the smudge should remain visible forever.

“sure to wear off after a while”
Could you fill in one of the vertical flutes instead? That might wear less.

If we were using them as handheld radios, that’d be perfect. Alas, they’re jammed into a bag behind the seat frame where they’re barely visible. This picture shows the “user interface” from about a foot over the bag:
I should put up a post showing the radios in place; pix on the bench really don’t do justice to the hideous tangle of cables…

Next time Ed, try to sink a small drill bit by a mm on the top of the knob and fill that will something white like correction fluid. You get a neat white mark.

Even better, that turns it into Quality Shop Time: I like it already!
The knobs probably pull straight off, so I wouldn’t be clamping the whole radio in the drill press…
