Hello, Fellow Elecrafters:
I changed out the main tuning knob on my K1 with a Yaesu FT-100 knob, and I
thought I'd report on the project.
I looked around for a weighted replacement knob 1-1/4" to 1-3/8" diameter,
with the requisite finger dimple. My search led to the Yaesu FT-100 main tuning
knob. When I called Vertex to order the knob, the clerk chuckled and right
away knew what it was for. He said, "For your K2? We've gotten about 1600
orders ... " He then proceeded to point out the need for Elecraft to order these
knobs in quantity to satisfy the demand. I was afraid the knob would be a
bit too big for my K1 (if everybody else is ordering for a K2), but I ordered
one anyway.
As it turns out, the FT-100 knob is ideal for the K1. The thick rubber ring
makes the overall knob diameter just a bit larger than the Elecraft knob, but
not too large to obstruct the XIT button. The weight and "knurled" ring give
a nice feel. BTW, the rubber ring will fit on the original Elecraft knob.
One problem I encountered is that the hole diameter is just a little under 1/4".
You have to drill it out to fit the K1 potentiometer shaft. It's brass (or
a similar soft, brass-colored metal), and not a problem using a steel bit in a
home drill press.
All in all, a nice upgrade for the K1. 73, Jim K5HO
