Schematic is here: ?
/g/BITX20/message/30731The 100k resistor between the diode and the 2n7000 is not in Farhan's original design.
I have no idea if it is a good idea or not.
It is the other 100k resistor that I am suggesting be replaced with a pot.

I suggest replacing that 100k resistor to the left of the diode with a 100k pot.
The wiper of the pot goes to the diode,
the two ends of the pot go to the 0.1uF cap and to ground (where the 100k resistor was).
You could just leave the pot in there.
Or you could twiddle the pot until you get the effect you want,
then measure the pot with an ohmmeter and replace it with a couple resistors.
