Hello,
I wanted to download 3.97 but I couldn´t get it.
K3 utility worked but in the Available columns appears only the versions I
already have:
MCU 03.79
FPF 01.08
DSP1 02.54
DSP2 02.54
DVR 01.03
Any Idea I am not getting the latest versions?
Thanks,
Jorge

Asunto: [Elecraft] K3 Firmware Rev. 3.97: new DSP NB algorithm, improved TX
INHibit, accurate S-meter w/AGC off, etc.
K3 beta-test firmware revision 3.97 (with DSP rev. 2.58) is now
available. This revision has several significant improvements; see
release notes below. (Note that "QRQ" mode -- enhanced high-speed CW
-- will be in the next release.)
Please send any questions to k3support at elecraft.com. For instructions
on how to load beta firmware, see:

MCU 3.97 / DSP 2.58, 5-9-2010
* TX INHIBIT IMPROVEMENT: If TX INH is active (see
CONFIG:TX INH), voice monitor and CW/DATA tones are disabled,
giving the operator audible feedback about inhibited status to
supplement the flashing TX icon.
* DSP NOISE BLANKER IMPROVED: A new algorithm has
been added that makes the DSP NB more effective on
some types of noise. Odd-numbered DSP NB levels (t1-1,
t1-3, t1-5, etc.) apply the new algorithm, while even-numbered
levels use the original. To avoid unwanted interaction between
the NB and on-air signals, always use the lowest effective setting.
* CW KEYING ARTIFACT WITH AFX/DELAY ELIMINATED:
The DELAY settings of AFX previously created a small audio
artifact when listening to CW keying in the presence of background
noise or signals.
* AGC-OFF S-METER IMPROVEMENT: Turning AGC off no longer
results in a drop in the S-meter reading. This was most noticeable
in the presence of strong band noise.
* K144XV S-METER NOW ACCURATE: The S-meter reading is
now adjusted to account for RX gain when the K144XV is in use.
* TX NOISE GATE IMPROVED: The voice transmit noise gate
now uses a downward expander rather than simple gating.
See TX GATE menu entry for further details.
* MANUAL NOTCH: Pitch now defaults to 1000 rather than 2000 Hz.
This starting point is a better compromise between CW and SSB.
* ESSB ON/OFF COMMAND: The new ES control command
can be used to turn ESSB on/off via a switch macro or from a
software application. The K3 must also be in LSB or USB mode
before ESSB ON takes effect. (See K3 Programmers Reference.)
* BN REMOTE CONTROL COMMAND (BAND CHANGE):
Previously this command was GET only, returning the
present band number (00-24). It can now be used as a SET
command to switch to the desired band. For example, BN00;
switches to the last-used frequency on 160 m. Note: VFO B
will also be restored to its last frequency used on the new band,
except in the case where CONFIG:VFO IND is set to YES.
