[Elecraft] P3: QSY knob mod

[Bob Cunnings]

I use the P3 with a fairly wide span to spot and pounce on signals in
the CW bands. The P3 is near the edge of the table and I find myself
most comfortable when placing the heel of my hand on the table edge
and twirling the QSY knob with the index and middle fingers to move
the cursor around the band. This was hard to do with the stock knob,
it seemed a bit small and I needed a little more friction also. While
rummaging around in a drawer I found a couple of those dipped vinyl
protective caps used made to fit SO-239 connectors was inspired. One
of these fits snugly over the P3 QSY knob. It fattens the knob
considerably and offers a lot more friction. I can twirl away
effortlessly now, and tapping is easy too. Here's a photo link:
