The new K3 Utility version is not required, but there are a few months of changes, and I'd encourage you to remain more-or-less current.
- K3 Utility functions that use EEPROM read and write have been sped up, and are more reliable. This includes configuration save/restore, crystal filter configuration, command macro read/write, RF Gain calibration, power-on banner save/restore, TCXO data entry. Configuration save (at 38400 bps) now takes less than 5 seconds. Reliability improvement comes from a (private) protocol that includes a checksum. This improvement depends on MCU support introduced in K3 MCU firmware version 3.83. Earlier MCU versions continue to use the older technique. - Filter configuration now inhibits enabling a filter wider than 2.8 kHz for CW. This was required as part of the MCU update for QRQ CW. - The K3 Utility no longer sends commands to alter the K3's "auto info" state. N8LP's LP-Bridge wasn't able to support the K3 Utility because it changed Auto Info. That impediment has been removed. LP-Bridge is an N8LP product that allows several PC application programs to apparently share a single COM port that is connected to a K3. You still should not attempt to load K3 firmware through LP-Bridge or any other K3 sharing software, such as microHAM's uRouter. - Fixed a bug in RF Gain calibration that changed the VFO frequency slightly. - Revised Tx Gain calibration to preserve the last-used frequency on each band. - Added a check during K3 firmware load to look for a P3, and if it's present, ask the user to switch the P3 off for K3 firmware load. This is a temporary workaround until P3 firmware supports a "pass thru" for K3 firmware load.
