* EXPERIMENTAL CW QSK MODE: 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 reduces audio artifacts heard in the receiver during CW keying on a noisy band, at the expense of a slightly longer receive-recovery time. (We hope to speed up RX recovery in a future release.) To verify the benefit of NEW QSK: First select a CW RX filter bandwidth of 400-1000 Hz, then transmit 20 WPM dits (at 0.0 watts) on top of an S5 or stronger carrier, or in the presence of S7 or stronger atmospheric noise. While transmitting, you can be in the CW WGHT menu entry, alternating between OLD and NEW QSK by tapping ‘3’ (APF).
* 60-M U.S. BAND LIMITS CORRECTED: CW/DATA, TUNE, and ATU TUNE are now usable on all 5 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.
* KX3 CHANNEL HOPPING UPDATES PX3 DISPLAY PER-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 m, which includes both CW/DATA and SSB allocations. See page 17 of the owner’s manual for scanning/channel-hopping setup instructions.
