Frank,
No way that I know of. I always grabbed the manual and manually set
everything back to defaults.

You must first tap DISPLAY to get into the DSP menu.
Without being in a DSP menu, a hold of STORE+RCL normally puts you into
a Direct Frequency Entry state which will display the dashes that you see.

While it's true that some digital modes can be heard well below the sound

the most popular like PSK-31.
The right answer is for me to move up to a K3.

Any attempt to compare my experience with yours depends on the noise, which
is as variable one place to the next as snowflakes.
But my K2 has the noise blanker in it, in addition to the DSP and all my K2

Jon,
The KDSP2 will reduce the noise - the nr is quite effective.
However, if you operate digital modes, I don't think you should be using
noise reduction with digital modes, it will reduce your copy. Many
digital modes can decode at or below the noise level anyway, and th

The nice thing about the KDSP2 is that you can tailor the settings to do
different things when required. I have had good luck reducing atmospheric and
similar wideband noise, effectively lowering the noise floor (sometimes to the

My K2 (SN 1872, rev A, firmware 2.04P 1.09) is equipped with a KDSP2

Three questions:
1.) What is the current KDSP2 firmware revision?
2.) Would I benefit from an upgrade? (I operate almost exclusively CW.)
3.) What would an upgrade cost me?

You have the latest firmware installed. Yes, there is a slight
difference between MCU 2.04P and 2.04r.
That one change was to remove the selection for the sidetone source.

Now I am confused too. The Elecraft website (in the Order Firmware

Maybe Lyle and Eric can figure out what is right - either the order page

KDSP2 has two firmware versions associated with it: the Control board

DSP, which interfaces only with the control board.
The latest versions are:
CTL 3.10
DSP 3.18

Hi all,
I have been fiddling with the KDSP2 for a while and am trying to get
my head around the settings for optimal CW reception. Yes, I know
that's all subjective, but I'd be interested in hearing what folks are
using for the denoiser settings (beta, decay, CW gain) as well as the
CW filter
For some reason the noise level was higher than normal at my QTH last
night on 40m. I struggled to pick out the signals at all--but heard a
faint CQ around 7.117 MHz. I fiddled around with the stock crystal
filters as well as the KDSP2's filters but was only able to hear the
signal well after

I'd like to have a variable bandwidth filter on my K2, controlled by an
encoder instead of a pushbutton with programmable steps.
I see the KDSP2 module uses open source code.
Would it allow me to sense a couple binary inputs (or even a variable
voltage) and write some code to vary the filter
The DSPx module hardware does not include an ADC to measure control
voltage, but it does have some unused digital I/O pins that could read
buttons, or perhaps an encoder, if you wrote the code to do it.
There is plenty of unused program memory and lots of available DSP
horsepower for such
I am in the process of installing the KDSP2 on the Control Board. When the

whenever the noise filters are used they seem to do much worse than this

I hate that module. There is no reset, and once installed it is the

In fact I pretty much put my K2 on the shelf after putting in the KDSP2.
Just my 2 cents.

Went through the SSB filter adjustments yesterday and today. Played
with the DSP settings, and got it all dialed in just so. Put it all
back together and no audio.
Took it apart and saw C1 from the KDSP2 daughter board sticking up in
the air. Nice, I remember the warnings about that NOW.
Dave,
The KDSP2 schematics are in the KDSP2 instruction manual.
The schematic shows C1 on the DSPx module as a 10 uF/16v capacitor
(probably tantalum, do not reverse it!). If the capacitor itself is not
damaged, you can likely make a repair with small gauge wire, assuming
there is enough
Hello to the List,
I realised that I had not finished the story about the problems I had
with my KDSP2. My ineptitude may serve as a cautionary tale for others

Anyway to recap:

the DSP processor board
Kevin,
Since you are searching for a possible break in the board traces or a
thru-plated hole, you may do better with a scan of the board rather than
the schematic. There are scans of the KDSP2 board available at Tom
Hammond's website www.n0ss.net

I assembled the KDSP2 recently and it worked fine. However, I assume
that solder had wicked up into the J2 contacts - it was stiff to plug in
