I tried the settings specified with my F5K with the key plugged directly
into the radio but I still experience delays or timing issues, lost
elements of characters or incorrect characters, however, when I use a
keyer plugged into the back of the radio I do not experience any
problems. I a

how long do the buffers take to fill after the relay closes?
I set my sdr1k to the fastest buffers, and listen to my Icom 746
sending cw.. the relay closeson the 746.. it sends a dit, and the radio
just starts to receive again before I can hear the signal in my srd.
I cannot see how that
Hi Mike,
I agree with your assessment of QSK, it's great for the contester or DXer
managing a run, but for a little pistol search and pouncer like me semi

My signal/one CX7A had very good QSK.
I found the noise while transmitting
to be irritating, much like voice VOX
with a short delay time so that it
goes to receive in between syllables.
It's nice to have a little quiet while
you are sending to think about what you
are communicating.
I suppose that
Hi,
I applaud you guys putting numbers to the issues. In my working life
our engineering department's slogan was: "The numbers will set you
free." I'm sure Dilbert agrees!
very best regards

Hey Frank,
Great news.
One way to sell the new architecture is a fancy driver to go with a nice
flexible Windows GUI... Who ever worries about the innards of a driver

Peace and happiness will descend on the Flex realm!

Good that you could measure the numbers there, Ed.
I don't know the numbers for any of my rigs, but I just did a quickie
listening test and the K3 definitely gives me audible band noise
conditions at 35. I am new to the K3 and don't really know how to get
the optimum from it yet - it probably d
Jerry has brought up an important point. We CW ops believe true QSK
means hearing between dots at high speed. I thought so myself until I
began looking closely at the performance of box-based rigs.
There is an easy calculation that shows why true QSK is difficult:
R/T + T/R - ES = Band Sound

not appear to make any difference.
Otherwise, I am very pleased with the CW improvements. Great
work, Ed!

That's not right. The entire audio subsystem inside the SDR software is

Thanks, Ed. BTW, what you describe as QSK is usually referred to as
"semi break in", or "Semi QSK" by CW ops. There is a world of difference.
For the guys and gals out there who may not understand the
distinction, CW ops refer to QSK as the ability to actually hear
activity on the band between
There have been a couple of problem reports with the latest QSK mods.
I considered reverting to the previous method, but decided to stay
with then new way for two reasons:
I can't figure how the problems reported relate to the QSK changes.
And even if they do the way forward is with the new co
Hi Ed,
Almost all "nearly" QSK CW T/R transition pops and clicks gone now
with this latest version. However, every once in a while, as I am
sending CW around 25 wpm, the radio will stop keying. When this

I thought I was finished with PwrSDR QSK a couple of days ago, but
then I had a few more thoughts...
There is a new version in the SVN branch w2rf\bin\release
My favorite settings are DSP 4096/256 at 96Khz/512. What are yours?
I honestly think that these latest changes take QSK about as far as
17 matches
