Hi,
Who is familiary with PSK D (Elecraft K3) mode?
DX4WIN generates audio stream (PSK31 from soundcart only).
How get the PSK D data stream?
Thanks for idea.
73,
Milan

Hello David,
If a PSK signal is generated in an early stage of a transmitter (or is fed
into an input of a transmitter), then all of the transmitter's stages which
follow should be linear to keep the signal clean. In the case of the
basic type of PSK 31.25 signal consisting of a single tone,
Oooops :-( In my message to David Moes, I said:
phase results in sidebands spaced
31.25 kHz each side of the main signal. If the transmitter's stages which
follow are not adequately linear, then IMD products could create
splatter.
I meant 31.25 Hz not 31.25 kHz.

Understood. I have already shortened the leads quite a bit. and made a
decent change in the voltage drop cant remember the difference.
Last night I was also able to make some tests (before the lead length

The short answer is that splatter can be caused by just about anything
between your keyboard and his audio out.
Analyzing just one occurrence is nearly impossible. There is a lot of good
verbiage in the archives about keeping your signal clean and maintaining
a means for inspecting that

Right!
He said he was going to set up an outside monitor to look at his signal.
Perhaps when that's set up it would be interesting to compare the Kcomm
generated text with just the K3 Utility.
Don't know why it would make a difference but could be a starting place if it
does.

I take it your running a typical 13.8v supply.
Running a stiff 15v supply cleans up the K3 TX IM3 dramatically.
The filter also keeps the key signals clean into the K3.

The only way to split on PSK-31 is to use XIT. Just go up the necessary amount
and transmit.

Why would split be used on a narrow bandwidth signal such as PSK31?
Would you not be just consuming twice the amount of bandwidth as needed?
I have casually operated PSK31 and I have not seen the band so crowded that
operating split would be needed.
Split operation is dictated by the desires of the DX station. If he is quite
rare, as in the case of VK0TH on Macquarie, he cannot hear the multitude of
stations calling simplex and those calling simplex cannot hear his reply. So
split is necessary to complete the contact. Exactly like cw,

The original question was about PSK D but the answers didn't address
that question.
Assuming that Bud was really wanting to use PSK D with text decode on
the K3 and direct CW to DATA then the K3 does indeed indicate SPL N/A.
In that case XIT does offer a method by which to go split.

I suspect that VFO-B is in a different mode. (You can view VFO-B information

and the second push transfers other information such as mode
Bud,
Most PSK31 waterfall software allows you to set the transmit frequency
different from the receive frequency on the waterfall display.
Yes, the K3 does not allow split in Data A submode - use your software
application.

Using PSK D today for the first time ever, I was not able to get split to work.
After setting both VFO's to PSK, then pushing split resulted in SPL N/A

wrong with PSK? Is split invalid for PSK? Thanks.

This is a show-stopper of a question. I have been running PSK for a
number of years, and have never observed anyone running split. With an
exceedingly narrow-band mode such as PSK31, it should not be necessary,
although occasionally someone will drop down right on top of your
offset, either

Hi all,
Is the sidetone/offset setting for the PSK-D mode adjustable? I noticed that
it is for the other data modes, but in PSK D it seems to be frozen at 1010
hz.
No, I'm not demanding Wayne/Eric change this if it's by design ;). Just
curious...
If I could send CW worth a flip, I'd use this
Apologies if this is a silly question, but I've been unable to find the
answer.
In the K3's PSK D mode, i.e. direct transmit mode, is the TX RX frequency
the indicated VFO frequency, or the VFO frequency plus / minus the pitch
setting?
It makes a 1010Hz difference!
Thanks in advance 73,
Ian

The Tx carrier is frequency is displayed in VFO A. This is also the Rx
frequency that corresponds to the decoder's pitch.
