2010-11-03 Thread Jan Erik Holm
Yes APF came out reel good, very well done! Don´t even know if
it was this good on the FT-1000D, at least not on the units I
did own.

Now if only AM RX was to be fixed I would be happy, as it is
right now AM (not sync AM) RX is more or less useless. It "got
broken" in the DSP code way back. I have written about this
problem before and I´m not going to repeat myself any further.

2010-11-03 Thread John W2XS

I would also like to thank the Elecraft crew for another great enhancement. 
I updated the firmware a few minutes before a local traffic net here. 
During the net, I was asked to receive 6 messages from a weak station.  With
both the NR and APF turned on, a marginal situation became solid copy.

BTW, this is my 47th firmware update since Beta 2-1 in June, 2008.  I have
never had an issue.

Given the value of both APF and Dual PB filters, the "menu dance"
to switch between the two is a very big drag.  Please provide a
way to select either function (I'd suggest "Hold" and "Long Hold"
as used with Link/Diversity) without resorting to the CONFIG

Re: [Elecraft] K3 Beta Release: APF for CW; "Fast Monitor" & improved TX gate for voice modes

2010-11-03 Thread Fred Jensen
WOW!!  I wondered who the pile up was for around 14017 or so.  Tuning 
down a couple, I heard an S[minus]1 signal I couldn't make out, sounded 
like 9A something, sometimes GT[?].  Figuring there wouldn't be a huge 
pileup on a 9A, I engaged APF.  Right out of the noise, maybe S3 and 
easily copyable was 9U0A.  As usual, K6RIM beat me to him.  I'm still 
digesting all the NR/NB/AGC stuff "The Smiths" sent me, I'm thinking 
this can only get better.

[Elecraft] K3 Beta Release: APF for CW; "Fast Monitor" & improved TX gate for voice modes

2010-11-03 Thread Bill [NS4C]

I loaded the beta firmware so I could see what all the APF buzz was about.
3D2A was spotted on 18070 so I turned the beam and he was there in and out
of my noise level. I turned on the new APF function and peaked the CW
signal. He was now 100% copy. Turned APF off and he was in and out of my
noise level again. Now I understand how good of a tool APF is for weak
signal CW. BTW The 3D2A is in my log.

Many thanks Elecraft,

Hi Wayne, never having used this sort of function before, I am pleased
with how well it works just the few minutes of playing with it.  Thanks
much.

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

Perhaps I had not noticed them before, but in tweaking on CW using the
WIDTH control, I can hear a slight audio pop on occasion which sounds a
bit like a scratchy pot and is certainly not the slight drop in audio as
the filters are switched in and out.  I notice it only when going from
150 to 100 Hz bandwidth but not back again.  It does not do it
all the time, however. I can repeat it if I widen to about 450 Hz and
then narrow it back down to 100 Hz and the slight "tick" is there each
time the switch is made from 150 to 100 Hz.

My K3 is a single receiver with 2.7, 2.1 kHz, and 500 and 200 Hz filters
installed.

BTW, are there filter plots for the Elecraft 5 pole filter available?

What a wonderful addition for CW operators.

[Elecraft] K3 Beta Release: APF for CW; "Fast Monitor" & improved TX gate for voice modes

2010-11-03 Thread Greg Buhyoff
Thanks so much, Wayne, Lyle and the Elecraft crew who worked on this, and
thanks to the alpha and early beta testers.  I downloaded the beta version
earlier this afternoon and used it for a couple of hours of CW operation.
Fantastic!  Have not had anything like this since my FT-1000 days.  My 7800
APF is a virtual joke.

Again, Elecraft continues to provide continuous improvements and
enhancements to an already great radio.  The K3 continues to morph into the
most flexible and option packed piece of equipment I have owned.

73 and thanks again to all for their work and ideas that went into this
including the many members here who gave input.

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

[Elecraft] K3 Beta Release: APF for CW; "Fast Monitor" & improved TX gate for voice modes

2010-11-03 Thread Wayne Burdick
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.

MCU 4.17 / DSP 2.65 / FPF 1.14, 11-2-2010

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.
