I'm also agree with Fran, at least an explanation from Elecraft about
this mod would be really appreciated.

I am now confused by the existence of two different mod's with the
same
goal.
It makes perfect sense to me that I should not be wasting Tx energy
on audio
frequencies as low as 20Hz. Beyond that I am somewhat in the dark.
Jim Brown and Stewart Baker have each suggested a modification to
improve
this situation.
I am at a loss to know which, if either, I should implement. I
must admit
that I an very tempted to incorporate the indicated improvements.
However,
I would have no means of evaluating the results and therefore look
to the
remainder of those on this list for further opinion.
Summary of the mod's are:
from Jim:
Change R14 from 1K to 2K.
Change C34 from 2.2hF to 0.22 uF.
Add 1uF in parallel with R15
from Stewart:
Change C34 from 2.2uF to 0.47uF
Change C31 from 2.2uF to 1uF
Change C20 from 0.33uF to 0.047uF
Is the situation severe enough to warrant an official mod for this?
Inquiring minds want to know.
Fran
