Subject: [Elecraft] K4 production software release (R32) now available
Release 32 has been beta tested (R32.BETA2) and has now been moved to
production status.
See release notes below, or on our K4 software page, or view them in the
updater on the K4 itself. (For your convenience, the list below shows all
significant changes since production release 31.)
Software development is continuing in multiple areas, including remote
control.
73,
Wayne

R32 (PRODUCTION) ==
December 13, 2022
- SSB/ESSB TRANSMIT AUDIO LOW-FREQUENCY RESPONSE IMPROVED: The nominal
SSB transmit audio low-frequency rolloff can now be moved down from about
200 Hz to 100 Hz. (Amplitude at 100 Hz then increases by nearly 20 dB.)
This selection is made using the new "TX Audio LF Cutoff, SSB" menu entry.
IMPORTANT NOTES: (1) The 100 Hz selection is *always* applied in ESSB
mode. (2) In addition to using this new SSB setting, you can control the
transmit passband in all modes using TX EQ. (3) If you use USB or LSB for
audio DATA modes such as PACTOR that require fast turnaround times, you
should not use the 100 Hz SSB setting, because it slows turnaround by
about 20 milliseconds. (The high-performance digital filter required to
obtain a lower passband has additional "taps," resulting in greater
delay.)
- KPA1500 / KPA500 LOSS OF BUTTON PRESSES: In previous releases, some amp
front panel button presses could be missed by the K4 due to the concurrent
handling of other band-change activity.
- RADIO LOCKUP DURING VFO MOVEMENT AT ~5600 KHZ: One operator discovered
a radio lockup when moving the VFO in the vicinity of 5600-5620 kHz. This
was due to incorrect lookup of ATU LC segment data, which has now been
corrected.
- TERMINATION OF DVR MESSAGES no longer causes occasional loss of mic
audio.
- REPEATER OFFSETS are now correctly applied to VFO B when in SPLIT.
- IMPROVED EEPROM DATA VERIFICATION.
FOR SOFTWARE DEVELOPERS & MACROS
- The "TQX;" command now bypasses other command processing delays to
provide a more real-time response during "TX;" / "RX;" command
transitions.
- DUPLICATE "TX;" COMMAND while in transmit mode no longer exits transmit.
- ADDED "EE0;" command to reset all radio state and menu parameters to
defaults, with the exception of factory calibration data.
- ADDED "TQX" GET COMMAND (extension to "TQ" TX status query): If the GET
query is "TQ;", then the K4 is considered to still be in transmit mode
during the S-meter holdoff time (300 ms), even though receive audio can be
heard. If the GET query is "TQX;", then the S-meter holdoff time is not
considered to be part of the transmit state. This allows an application to
find out more quickly when actual RF transmit has ended, which may result
in a more responsive user interface (when playing DVR messages, for
example).
- ADDED "AG$+nnn" (AF gain increment/decrement).
- ADDED "VC" command to properly handle configuration of per-mode coarse
tuning steps. "VT" command also improved to correctly handle A/B VFO
swaps, etc.
- IMPROVED "#HWFC" command to allow modification of waterfall color mode
for both panadapters on the external monitor.
