RATS!

When I switched to the KDSP unit from the KAF2, a pin-prick short but =
sharp click was introduced at each make of the QSK.  this click was =
unaffected by the AF gain control, but was affected by turning down the =
sidetone volume.  Also, turning off the DSP (bypass) would eliminate it.

I first tried Wayne's mod with a resistor in the mute line, no change.  =
Now I have Lyle's mod installed.

The click is still there, but it is changed.  It is less.  The click =
that remains is unaffected by turning off the DSP.  The click is =
unaffected by changing the sidetone volume.  The click IS affected by =
changing the AF volume. =20

I believe that Lyle's mod eliminated the original click in the sidetone, =
but introduced one from a different source.

Ideas???

tnx,

fred - kt5x, please send a copy direct as I get the digest form of the =
list
