K3 MCU firmware rev. 2.38 (and DSP firmware rev 1.90) is now officially
a regular production release. We encourage all K3 owners to download
this revision.
Many important changes and additions have been made since the last
production release (2.02). Here are some highlights:
* Complete sub receiver support, including new DIVERSITY mode
* ESSB (Extended Single Sideband) transmit
* 10 HZ CW sidetone increments
* More accurate transmit power control and LSB/USB equalization
* Many changes to the user interface to simplify or clarify operation
* Signal processing improvements (DSP filter centering, etc.)
* Power-up KEY/PTT lockout for safer interoperation with other gear
* Many new or improved commands for computer-control applications
* Simplified firmware load process
Be sure to use revision 1.1.6.3 or later of our K3 Utility application
to download the firmware. For instructions, see:
