Whoa, hold on a tick....

Just as well that I didn't use the biasing device I made, read this:

http://www.worldwidedx.com/general-cb-services-discussion/157713-en369fn-mosfet-companion-cbtricks-errors-drawing-correction.html

Since PsiDOC did the math, I used his formula of .000185 / (desired bias voltage) = ~47k ohm resistor for the value of R2 in the EN369FN biasing device for a 4v gate voltage. 20k ohms will give the more desirable 3.75v gate voltage, as shown in the above graphic.

Soooooo........Using a 100k ohm VR @ R2 in parallel with a 20k ohm fixed resistor will make the gate voltage variable for the EN369FN?
That's a guess BTW; but it seems logical tho . . . OR adding a 100k ohm VR between the gate and source pins using the EKL EN369FN device . . .
