Wayne I believe I have found a bug. If the ATU TUNE is operated with the NR
enabled then on return to receive their is a noticeable drop in receive audio
level and more importantly there is no longer any TX power output. Also there is
no indication of ALC or CMP but the TX LED does come on indicating that the KX3
is in TX mode. I am not sure whether the receive sensitivity has dropped with
the drop in receive audio. This also happens when the TUNE function is enabled.
There is still power out when the ATU or TUNE is enabled but not when TXing from
the MH2 mic. The receive audio is retored when the TUNE function is operated.
The TX output is restored if the KEYER/MIC control is moved a little while
operating the PTT. The problem does not appear to exist when the NR is not
enabled. Others may like to check this and confirm it is not just my KX3 with
the problem
Sorry to spoil your weekend Wayne

KX3 beta firmware rev 1.44 (with DSP rev 1.16) is now available. See release
notes below.
You'll need the KX3 Utility application to download and install firmware. For
full instructions on loading beta releases, refer to our KX3 software page:

* NOISE REDUCTION (NR) EASILY ADJUSTABLE: The overall level of noise reduction can now be set using
the knob above the NR switch (AF/RF-SQL). When NR is turned on, the present setting will be
displayed on VFO B for about 2 seconds. To select a new setting, rotate the knob before the display
times out. The setting is independent for CW and voice modes. Note: The range of this parameter is
0-10, corresponding to the "mix" or "M" parameter of the RX NR menu entry. See
below.
* RX NR MENU ENTRY CHANGES: The RX NR menu entry can be used to adjust all
three NR parameters (B¾ta, DÞcay, M=wet/dry mix). The M parameter now has a
range of 0-10, matching the range available when the knob above the NR switch
is used (see above). As before, all parameters can be adjusted separately for
CW and voice modes. In most cases the factory default settings can be used for
beta and decay, and the mix adjusted for the desired overall amount of NR using
the knob (without using the menu). You can also now reset all NR parameters to
factory defaults by holding CLR.
* DVR PLAY/REPEAT FIX: DVR play no longer drops messages.
