[1000mp] W8JI Keyclick Mod

[Earl W Cunningham]

BTW, the two pots, R1 and R2, in Tom's key click mod were originally 10k
and 100k.  After I tuned them for minimum clicks I measured R1 at 7.5k
and R2 at 100K (full tilt).  I replaced the pots with 7.5k (two 15k
resistors in parallel) and 150k, which is where it sits now with +/-300
Hz clicks.

Based on that, I suggest that you do the mod using a 20k pot and a 500k
pot.  After you tune them for minimum clicks (by listening on another
receiver using its narrowest CW filters), measure the pots and replace
the with fixed resistors of the correct (tuned) value.

The INRAD "keying improvement" mod only reduced the clicks to +/-800 Hz
(which were originally +/-2500 Hz), BTW.
