[Elecraft] K3 Beta firmware Rev. 3.04: AGC fixed; various improvements

[wayne burdick]

K3 beta-test firmware revision 3.04 (with DSP rev 2.11) is now 
available.

The most noticeable change is that the problem with normal AGC decay 
(CONFIG:AGC DCY=NOR) has been fixed; you can now use NOR or SOFT decay. 
(SOFT decay is designed for use in pileups, but also improves fidelity 
in voice modes.) Other changes are noted in the release notes, below.

Please send any problem reports to k3support at elecraft.com. For 
instructions on how to load beta firmware, please see:

We recommend that you use the latest revision of K3 Utility, which can 
also be found on the K3 software page.

MCU 3.04 / DSP 2.11  March 25, 2009

Misc. Improvements:

* DSP AGC FIXED: You can now use the original fast and slow AGC decay 
setting (CONFIG:AGC DCY = NOR) if desired. In pileups or when listening 
to voice signals, try setting AGC DCY to SOFT. This can reduce in-band 
IMD by 15-25 dB. Also see release notes for rev 3.03/2.10 concerning 
AGC HLD and overall AGC options.

* TUNING JUMPS DUE TO SPURIOUS SIGNAL REMOVAL: The use of CONFIG:SIG 
RMV no longer causes frequency tuning errors in USB and CW REV modes.

* MEMORY RECALL: This now preserves all settings that should be 
per-band (not per-memory), including PRE/ATTN and sub antenna 
selection.

* BSET INTERACTION WITH RIT/XIT: Using BSET no longer causes an 
unwanted change in RIT/XIT settings.

* FIXED FA/FB COMMANDS AND 1-HZ TUNING: Non-zero 1-Hz digits are now 
preserved when FA/FB commands are received and FINE tuning is in 
effect.

* ANT NAME FLASH: The antenna name is no longer flashed when A/B or REV 
are used. It is still flashed on any band or antenna change.
