[Elecraft] New KX3 field-test firmware: 60-m band limits fixed; no RX EQ in DATA modes; etc.

[Wayne Burdick]

Hi all,

Below are the release notes for KX3 rev. 2.32 field-test firmware. If you're interested in testing any of these changes to the firmware, please email me directly. I'll take the first 20 or so. If all goes well, the new code will be available as a beta release next week.

73 & Happy New Year,

MCU 2.32 / DSP 1.32, 12-30-2014

* 60-METER U.S. BAND LIMITS CORRECTED:  CW/DATA, TUNE, and ATU TUNE are now all usable on the lowest and highest channels. Previously, BND END was displayed in some cases. Note: This also applies to other countries where the U.S. band limits are used. 

* RX EQ NO LONGER APPLIED IN DATA MODES: Previously, the RX EQ settings for voice modes were being applied to data modes.

* CHANNEL HOPPING UPDATES PX3 DISPLAY FOR EACH MODE:  When channel hopping is used (by tuning the VFO or scanning), the PX3 display is now updated based on the mode of each channel (frequency memory) in the hop range. This is especially useful on 60 meters, which in some cases includes both CW/DATA and SSB channel allocations. See page 17 of the owner’s manual for scanning/channel-hopping instructions. 

* EXPERIMENTAL CW QSK CHANGE:  Tapping ‘3’ (APF) in the CW WGHT menu entry selects either OLD QSK (original) or NEW QSK (which purges the DSP’s audio pipeline on every key-down). NEW QSK may reduce audio artifacts heard in the receiver during CW keying on a noisy band, at the expense of a longer receive-recovery time. We hope to improve this further in a future release.
