[Elecraft] KX3 Beta firmware rev. 1.44: Easier NR adjustment; DVR message play dropout fixed

[Dave Jones]

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

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.

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.
