[Elecraft] New KX3 field-test firmware, rev 1.41: improved audio, FM fixes, LED brightness control

[Wayne Burdick]

Hi all,

This release of KX3 firmware has several significant improvements. See release notes below.

We'd like to release this to beta test on Monday, but we could use some additional pre-testing. If you're interested, please email me directly and I'll send you a copy.

KX3 MCU 1.41 / DSP 1.13, 3-26-2013

* AF GAIN SMOOTHER AT LOW END: The AF gain control now has finer granularity at the low end. To accommodate this , the gain range is now 0-60 (was 0-40).

* INTERNAL SPEAKER BEHAVIOR IMPROVED:  (1) Fixed bug that caused audio output mute/unmute cycling on strong signals. (2) Gain distribution changed to reduce speaker overdrive condition related to CODEC output. (3) Audio EQ optimized for speaker.

* FM DEVIATION AND FM MIC GAIN SETTING BEHAVIOR CORRECTED.

* NEW LCD BRT MENU ENTRY: Allows setting of LED brightness for the backlight-off case only. (During adjustment of this menu parameter, the backlight will automatically be turned off if it was on, then turned back on when the menu is exited.)
