K3: QRQ high-speed QSK

Until Tom said "I can't use my CW pulser with the K3, and now I know why.",
I would have said:

Use an external keyer (such as the Super CMos from Idiom Press) for your
tests.
Real men don't use built-in keyers.

And don't mistake the 'sound' of 100 WPM for a slowed-down version.
It ain't the same.

Re: K3: QRQ high-speed QSK

A pro friend of mine cruises at 60wpm using the built-in keyer of my club
746 (Mk1) in iambic mode. I don't know what it sounded like at the other
end but the QSO lasted several minutes with many overs. I don't recall if
it was QSK. He made no complaints about the rig and he's used to all kinds
of rigs and big into dxpeditions. I could ask him for his opinion on this.

I'm surprised to read of resistance to this enhancement, anything that helps
sell more K3s is good for me.

Re: K3: QRQ high-speed QSK

During a recent contest, one speedy cw op was cruising something over 30 wpm
but was hard to copy as there was no tone at all on his signal, nothing but
key clicks were being transmitted. No, he was not near me. Unknown radio.
Not something I would want anybody to identify me with sending.

There are some really good QRQ ops out there. W4BQF and W2UP come to mind.
I know that W4BQF routinely copies and sends over 100WPM, and he uses an
Icom 7700. Having owned the '7700, its QSK is very fast -- until you add an
external amp where keying artifacts begin appearing on anything but the
fastest switching amps. The '7800 I owned did not have this problem, nor
does the K3.

I agree that getting the K3 to run more accurately when using faster CW and
an external keyer would be a welcome update -- but not at the expense of
introducing any other artifacts (e.g., clicks, delayed T/R time, etc.)

Re: K3: QRQ high-speed QSK

This is a *little* OT, but I've just read in a 1914 WT book that they were
regularly running at 300wpm on spark transmitters. The very clever trick
was to operate the spark continuously and FSK it by switching between taps
in the antenna tank. The receivers were direct conversion using rotary
generators on nominal freq then recording the difference on a pen recorder -
I suppose an undulator by another name. I don't think FSK and DC were
phrases in common use at the time. Astonishing.

Re: K3: QRQ high-speed QSK

Who the heck is copying that and what are they copying???

The highest speed record for a long time, of copying
unexpected text, was only around 70-80 WPM. That record held
the whole time I was growing up, and it was from the 30's I
think.

It is certainly impossible to copy 300 WPM without decoding.

I have some nagging questions about these speed claims.

Re: K3: QRQ high-speed QSK

Tom

Copied by machine onto tape, then passed slowly in front of a typist who
read the ups and downs and typed from that. My father did this in the 30's
from recordings at >100wpm to his typing speed of about 30wpm. I've seen
the machines in the Poldu museum but they can't demonstrate them because
they are running out of tape!

Re: K3: QRQ high-speed QSK

In reply to this post by Ralph Parker

A friend of mine and I experiminted to see if the K3 could hear a bk during a transmission at high speeds

He was using the K3 with a pre BETA version, and I was on a Icom 7700. He would send a macro at a high speed, and I would try to break him using two letters (ie). Almost always he could hear my first break attempt. We went up to 75 wpm and he could still hear my bk.

So, we are wondering about what is going on concerning this thread. Now, it is possible my friend is hearing between words, but the bk could be heard almost 100%.

My friend says the delay should be set to double zero on the K3 for it to work????

Re: K3: QRQ high-speed QSK

I am not sure if this has been mentioned yet, but another setting that
may have an affect on this is switching between "New" QSK and "OLD" QSK
by tapping 3 under the CW WGHT Menu Item. I think that the default is
"New". I believe "Old" is supposed to provide better QSK performance
while "New" reduces keying artifacts.

That's good to know. Of course if it was pre-beta as you mention, changes
in firmware by release date could throw this off, but it's still
encouraging.

> So, we are wondering about what is going on concerning this thread.

It's not just about hearing the breaks -- it's also how good the K3 sounded
at those speeds.

W5UXH pointed me to some recordings of tests by N4LQ and I have to say, even
if things weren't perfect, I didn't hear anything too objectionable
(granted, I was very tired, listened to only a couple samples, and
briefly). I've had a couple ops offer to let me hear some on-the-air tests
and I'll take them up on it.

What may be acceptable performance to a casual CW op or to a contester may
not be acceptable to a QRQ QSK guru. At the same time, it's understandable
that reworking the K3 to achieve guru-level CW performance at this stage may
be in the best interest of a niche group of ops but not the company or the
majority of ops.

While I still feel that it's a shame to not achieve solid performance at
speeds pushing 100 WPM on a modern, high performance rig, for such a basic
and fundamental mode, I have no doubt there are tradeoffs involved and that
the designers are focusing on putting their money, time and efforts on what
most ops will consider most important.

Thanks for all the great responses in this thread.

Re: K3: QRQ high-speed QSK

In reply to this post by Tobyp

A breaking station sounds like a clicking sound instead of a tone on the K3
at speeds over 30-35wpm but at least it can be heard. The main problem is
with keying irregularity. Yes, the dits are a bit short but that can be
compensated for. The real problem is random variation between characters.
For example, at high speed, an H could end up sounding like SE. It really
strains the receiving op to interpret what you're trying to say.

Re: K3: QRQ high-speed QSK

In reply to this post by Andrew Moore-3

While it's gracious of you to give the K3 the benefit of the doubt in the hands of "QRQ QSK gurus", I'm also not convinced this is a true failing of the K3, if it's true (my K3's dits sound ok to me at 50wpm full QSK, tho slightly shortened).

In fact, compromise is a hallmark of good design. The hardware limits that Guy talked about earlier are real so you have to be accommodating in those regards if you're going to do the entire radio right. Putting it another way, one would have to wonder what other things have gotten short shrift in those radios that do somehow manage to do full QSK at 100wpm cleanly. If it's the 7700, the rest of the RX performance in more useful areas is easily exceeded significantly by the K3. If it's the 7800, the K3 still exceeds many of its capabilities and at about 1/5 the cost.

I will say I'd be slightly more concerned if QRQ performance wasn't good in semi-breakin mode. That would be a more legitimate gripe - has anyone assessed the K3 at those speeds in non-QSK mode? Like I said, I only have the ability to make 50wpm with the built in keyer (cocoaModem can go faster but it's operating mode is J2A) so I don't know how it does above that.

I'd personally kind of put this around the level of the QRP threads and maybe a little above the knob threads. Not overly impressed.....

Ted McElroy @ something like 74+ WPM back in the early thirties I think,
I could Google it I guess. The legend [urban or otherwise] is that the
code began, he calmly sat down at the mill, lit a cigarette, took a
couple of puffs, and then started pounding the keys. The legend further
states that after the run finished, he was still pounding the keys for
some time [3-15 minutes ... 74.34 percent of people make up their own
statistics so who knows]. That he did make record copy at that speed is
without question, without the embellishment. That the record hasn't
been broken since suggests to me that it may be getting close to some
physical limit. Ted went on to found a company manufacturing keys and
bugs of some fame.

I'm kind of with you Tom. I can make solid record copy at 25 WPM or so
if I don't have a glass of wine with dinner just before sitting down at
the rig. I can converse pretty well at 30-35 in my head, writing down
only notes. I can contest at D4B/C speeds so long as he doesn't send me
very much and I have a pretty good idea what it's going to be :-) Real
conversation ... one which involves questions and meaningful answers ...
at 100 WPM or above is something I'd like to see. I'm not from MO
but show me.

I watched the QSK keying waveform from my K3 [#642] on my Tek scope
sending just a string of dots. It stays "good" based on what QST
publishes in product reviews of "good" keying up to about 50 WPM. Above
that, it began to look "squished" in time, and at 60 or so was pretty
square, somewhat uneven in time, and was sounding fairly rough in the
monitor rx. I think Elecraft says 45 WPM max which, since they seem to
be a crafty bunch, would assure meeting their specification.

Tom - I was reviewing some of the archived posts and ran across this one.
FYI, QSOs at 100 WPM happen on 40 CW and on the Internet (iCW). This is
copying in one's head, not on paper. There are a handful of guys, and one
YL, who have broken the 200 WPM barrier with RUFZ, copying a single callsign
at that speed. I forget who was first - either Goran, YT7AW or Fabian,
DJ1YFK, both of whom I've met at the HST competition - and they look normal
:.)

There are also some incredibly fast eastern EUs who copy very high speeds on
paper with a shorthand system. I presented at the Contest Forum in Dayton
4-5 years ago and showed a picture of what the shorthand looks like.
McElroy's ~75 WPM (on paper) record is long gone.

Re: K3: QRQ high-speed QSK

Please get this correct! He did not copy at 200 wpm. He copied one call sign
at 200 wpm, but copying code and/or having a QSO at that speed is a
completely different situation. What he did was excellent but as I just
said, copying one call sign and having a QSO at those speeds is quite a
different animal.

Tom - I was reviewing some of the archived posts and ran across this one.
FYI, QSOs at 100 WPM happen on 40 CW and on the Internet (iCW). This is
copying in one's head, not on paper. There are a handful of guys, and one
YL, who have broken the 200 WPM barrier with RUFZ, copying a single callsign
at that speed. I forget who was first - either Goran, YT7AW or Fabian,
DJ1YFK, both of whom I've met at the HST competition - and they look normal
:.)

There are also some incredibly fast eastern EUs who copy very high speeds on
paper with a shorthand system. I presented at the Contest Forum in Dayton
4-5 years ago and showed a picture of what the shorthand looks like.
McElroy's ~75 WPM (on paper) record is long gone.

If you'd like to hear QRQ CW, I invite you
all to visit our website.

http://qrqcwnet.ning.com/

Here you can listen to recordings of QSO's at
100+ wpm, find tips, advice
and software to help you make the jump from
QRS (<50 wpm) to QRQ. There is
also software to allow you to use ICW,
Internet CW. ICW allows you to
participate in QSO's, roundtables and club
nets, when the bands are down.
By the way, CW at >100 wpm is often mistaken
for some sort of digital mode
transmission, as you'll see, if you listen to
the recordings on the website.
Joe, KH6/W3GW has a QRQ article in the most
recent CQ magazine (Sept. 2010).
An expanded version is also posted on the
club site.

QRQ may also be found on:

- the FOG (Fast Operators Group) net, Mondays and Thursdays at at 8 p.m.
Eastern (Tue/Fri 00:00 UTC). They run a 60 WPM net but anybody interested
in improving their speed is welcome to join in. (note: used to be
Tuesday/Thursday but changed a while back to Monday/Thursday)

- CFO (Chick Fat Operators) informal sked, Tuesdays at 9 p.m. Eastern (Wed
01:00 UTC). They tend to not run as fast as QRQ (> 50) but run anywhere from
30-60 on the sked, depending on conditions and abilities. All are welcome.
Usually runs for an hour. For more info see the CFO Home
Page<http://groups.google.com/group/Chicken-Fat-Operators-Club>

(sorry for the plugs and slightly OT, list...)
