I have just loaded the latest firmware.
The NR is certainly different and appears to be a big improvement although
at aggressive settings the audio output is very attenuated.
There is another effect which doesn't seem to have been published. That is
the maximum output that can be set by
Barry,
The power dropped to 110W with the previous public beta I think, in the
interest of spectral purity as I recall.

Barry, the power level was dropped to 110 some time ago.
Also, F3-4 and F4-4 are for instances of high signal ratio and noise; i.e.
strong S9+ signals with high noise levels. It is still recommended to Use
F1 and F2 settings for the best results.

Actually it was published in the Firmware release notes...
There is another effect which doesn't seem to have been published. That is
the maximum output that can be set by the power control is now 110 watts
instead of 120 watts.

I brought the K3 (#722) to work today once again, this
time to check the FM operation of the radio. I had
calibrated the oscillator a couple of weeks ago, and
it has only drifted 16Hz since then! Measurements
taken on the same equipment, same freq standard
Motorola 2670, Spectracom 8195A.

Elecraft need to see how other manufacturers configure their
transceivers... The TS480, which covers the same bands as a K3, has
wide/narrow TX deviation which toggles between the two when the FIL/Nar
button is held down, this switches between 2.5 KHz and 5 KHz maximum
deviation and

Sorry for the last incomplete post.
