K1 : W3FPR K2 Fixed Audio ??

[wf8o]

I have a K1 that is about a year old.  Love it.  Sometimes I like to use the K1EL K42 keyer with it.
This keyer is a CW Keyboard and a Morse Reader coupled to a dynamite good Message Memory function.
This setup works very well. But presently, I am using a splitter off of the headphone jack.  This is usable,
but a "line level" fixed output would be nice to have.  Has anyone already solved this issue?  It seems that the W3FPR circuit and a 1/8" jack next to the keyer jack would work.  Audio could be tapped off of the (input/output) of the existing LM386 through a suitable cap. - I think.  Any thoughts??

Sincerely,

Since you specify the W3FPR circuit and "fixed level" audio, you would
want to make any connection *before* the AF Pot.  My guess is that the
best results would be obtained by connecting the W3FPR circuit across
the AF Pot (pins 2 and 3 of P1 on the RF board) exactly as the circuit
is used in the K2.

Joe's selection of points to connect is good IMHO.  I believe you want
the point to be after the muting.
