[Elecraft] FT-100 Knob for K1

[We5f at aol.com]

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
