KX3 rev. 2.30 is now available for beta test (see release notes below). A number of KX3 owners field-tested this release, and nearly all reported significantly improved SSB speech compression. Those who use CW or SSB modes with the internal KX3-2M or -4M module have confirmed improved CW timing and higher SSB power output.
Instructions for loading beta firmware can be found on our KX3 firmware page: http://www.elecraft.com/KX3/KX3_software.htm NOTE 1: If you don't see the new releases on our web site, it's probably because your browser has cached an older page. Just hit your browser's "refresh" button (usually a circular arrow icon). NOTE 2: Turn off your PX3 (if applicable) when doing KX3 firmware loads. This requirement will be eliminated in future versions of KX3 Utility. 73, Wayne N6KR * * * MCU 2.30 / DSP 1.32, 12-03-2014 • SPEECH COMPRESSION IMPROVED: Corrected internal DSP stage gain, resulting in higher output levels with compression turned on. • 2-M/4-M SSB POWER OUTPUT IMPROVED: Max power output improved with and without speech compression turned on. Note: The KX3 will automatically reduce 2-m/4-m power output if safe levels of SWR, current, or temperature are exceeded. (You’ll see HI SWR, HI CUR, or HI TEMP flashed on the VFO B display.) This is more likely to happen when heavy speech compression is used, or when using a whip connected directly to the radio. We recommend reducing power to 2 to 2.5 W as required in this case to avoid the automatic power rollbacks or RFI problems. • 2-M/4-M CW TIMING IMPROVED: Dot length is now more consistent. • 4-M/6-M DIRECT FREQ ENTRY FIXED: Direct frequency entry to 6 or 4 meters now works correctly with a KX3-4M module installed. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
