K3 Beta Firmware Rev. 3.57: Synchronous AM Detection (AM-S); misc. improvements

[n7ws]

Good grief.  Sounds like another misdirected post to a devotional list.

Congratulations Jeff,now you are riding a real horse,,and after one month using it,the "Yaekenicom" will remain as a nightdream you had but when you woke up you came back to the real world of a pleasure and performance in your hands.Welcome to the increasing family of Elecrafters.
73 mate.

Don't know if my PM got through, but to make it official - the CW-to-data bug with the internal keyer is still in this beta. I didn't see anything in the release notes about it, tho, so I figured it's still on the ToDo list....

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,

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.)

* * *

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 Programmer’s 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.

Hi Brian,

I'm not sure if you are speaking of the Manual or Auto Notch.  After reading
your post I decided to check out the Manual Notch

I used the spectrum display portion of EasyPal (SSTV program).  The observed
'Valley of the Notch' seems to be in the realm of 400 to 500 Hz in width on
both CW and SSB for the Manual Notch.

There is a newer K3 Utility version available in the ftp.elecraft.com\P3
folder that is being tested by our P3 Field Test team.  

I've asked to have it published to our Elecraft K3 software web page, but
the last few days have been very hectic in Watsonville; they're busy getting
the backlog of P3s out the door.

The new beta K3 firmware was packaged with an updated
K3UtilityVersionInfo.txt file that causes the message about a newer K3
Utility version being available. Sometimes we have to guess what order
things will go out, and this time I guessed wrong.

Your current K3 Utility will do what it's supposed to do with the new
firmware. Or you can install a newer one from the ftp site.

Hi,

The FTP site is a little confusing. I can't find the usual zip file for 4.05. I find a zip for 4.03 and it looks like if I download that and replace hmcu403.hex with hmcu405.hex and the release notes file, I should be all set? All the other files are unchanged from 4.03? It's much easier if each new release has a complete zip file. I also found and downloaded the install for utility 1.3.7.26.

Knut-
4.05 has been designated a regular production release. You do not use the
FTP method for regular production releases, only for beta releases. Just
start K3UTIL, and check the box that says "Copy new files from Elecraft into
local folder". Then click the button that says "Check Versions Now". It
should recognize the new firmware and download it. You can then load it into
your K3.

Hi,

OK, that will work for me. I like to be in charge of what I download and where I put it so I don't like to use the utility's automatic update feature. I have a subfolder for every version I have ever downloaded from Elecraft, each with a shortcut to the utility. It would be nice if Elecraft would provide a zip file with all the necessary files, whether it's a beta or not. But I am OK for now.

The FTP site isn't very clear about which files apply, so just download them
all (ignoring the folders) to your stick and the Utility will sort it out.

  Knut,

I like to keep all my versions separate also.

Later versions of the utility will create a directory for you. In the "Local folder
for Firmware" box, just type it in, or browse to your location, then add the
\dirname. After the first time, all you have to change is the dirname.

You still have to check the "Copy new files" checkbox, and hit the "Check version
now" button, to do the download, THEN hit the "Send checked items to K3" button to do
the actual load

You are just as much in charge this way, it just hides the somewhat convoluted nav on
the Elecraft web site.

73, Mike NF4L.

K3 beta-test firmware revision 4.14 is now available. The most  
important change is to the behavior of the A/B and REV switches when  
the K3 is used with a P3. (See release notes below.) You'll also need  
to install revision 0.36 or later of P3 firmware, if you haven't  
already.

Please send any questions to [hidden email]. For instructions  
on how to load beta firmware, see:

* P3 UPDATED CORRECTLY ON K3 "A/B" SWITCH PRESS.

* P3 FUNCTIONS CORRECTLY AFTER "REV" SWITCH PRESS:
Previously, holding REV at the K3 would cause the P3 to stop
tracking K3 VFO movement. Note: At present, holding REV
does not result in any change in the P3 display. This will be
changed in a future revision of K3 firmware.

* BN REMOTE CONTROL COMMAND (BAND CHANGE):
This command now changes bands more quickly.

K3 beta-test firmware revision 4.17 (with DSP rev. 2.65) is now  
available. This release includes our new APF (audio peaking filter)  
for CW mode, which has been helping K3 field testers work "extreme"  
weak DX for the past several days.

For voice modes, there's a "Fast Monitor" option (TX voice monitor  
without the processing delay). Also included is a much-improved TX  
Noise Gate.

See detailed release notes below.

NOTE: Be sure to install all firmware files for this release,
including FPF 1.14. Otherwise your menu text will be incorrect.

* APF (AUDIO PEAKING FILTER) ADDED: APF provides enhanced
copy of weak signals in CW mode, and is especially useful when
signals are at the noise level. The K3’s APF is patterned after
the most successful analog APF implementations, and is equally
effective in user tests. To use APF, make sure CONFIG:DUAL PB
is set to APF. (This is the default. “NOR” restores the original DUAL PB
function.) Then hold DUAL PB to turn APF on/off. A special DSP
graphic display is used to show that APF is in effect. At the time
APF is activated, the regular I.F. SHIFT setting, if any, is “frozen,”
and SHIFT then controls the center pitch of the APF filter in 10-Hz
steps. APF is independent for the main and sub receivers, as well
as for presets I and II. Switching between these two presets is a
convenient way of turning APF on/off quickly.

* ADDED VOICE TX “FAST MONITOR”: Normally the voice
monitor includes a ~20-ms delay, which is necessary to hear how your
on-air signal will sound (with compression, etc.). If you prefer to not
hear any delay in the voice monitor, set CONFIG:TX MON to FAST.
Note: You’ll still hear the delayed and processed monitor if you
adjust the MIC, CMP, TX EQ or TX GATE settings while transmitting.

* TX NOISE GATE IMPROVEMENT: The Noise Gate/Downward
Expander for voice modes has smoother response and much
improved performance near the threshold.

* NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT and
WIDTH when using very narrow DSP filters no longer causes
‘pop’ artifacts.

Hi Wayne

The APF is fantastic. This is the best enhancement to the K3's receiver ever.

The APF performance puts the K3 ahead of every other radio  on CW receive. There is just no comparison. Anyone not using a K3 with the APF will be at a huge disadvantage in a contest.

The APF is  scary  with its potential. This is the first time that a DSP ënhancement has impressed me.
