[Elecraft] Firmware 4.18 APF adjustment using shift control

Richard and fellows,
    I too have not experienced the drop in SSB output.   I am still using
version 4.17.   There is probably more to this problem than is immediately
obvious and for that matter I wonder if the original Alpha testers ever
experience the difficulty in the original testing.

A fellow Swiss ham and I apparently were among the lucky few not to
experience any SSB power issue with Release 4.17/2.65. I wonder whether this
has anything to do with some interaction with filters or other settings.

But now after installing 4.18/2.67, I noticed that turning the shift to
exactly 1 kHz will mute both receivers and only impulses from the encoder
are heard (fairly loud!) until shift is returned CCW to below 300 Hz.

Not a big issue since only slight moves around my 700 Hz sidetone are
normally required.
Just wanted to point out that the loss of SSB power does not seem to occur
on every K3.
