[Elecraft] How is K3 QRQ QSK performance 50-100 WPM?

[Steve Ellington]

I tested QRQ CW using SpectraVue to display the dits and did not rely on my 
"opinion" of how it sounded. Above 45 wpm, the dits are of random length 
which makes copy difficult for those people who normally copy above those 
speeds. I used both Winkey USB, the K3's internal keyer and an external 
keyer. Using semi-QSK, QSK mode or even "Test" mode made no difference. The 
problem has something to do with the rig's CPU capability.

What got me started on this was during a QSO with a friend at about 50 WPM. 
He had a sharp ear and informed me that something wasn't quiet right. Since 
then, I've kept my speed below 45 wpm and suffered with the slow QSK at 30 
wpm and higher. Otherwise the K3 is the ultimate rig....For some things.

Andrew, I can't begin to key at 45 WPM so I have not responded. The best I 
can copy call signs in contests is around 50 WPM and the K3 sounds fine to 
me at 50 and I don't have any complaints using a WinKeyer USB. I have keyed 
it up to 100 WPM with the WinKeyer and the DTR pin of the RS-232 port. It 
sounds like CW, but I cannot copy that fast so I am not sure. I seldom use 
the keyer in the K3 because I prefer straight key or bug but it works fine 
up to 27 or 28 which is my limit for paddle keying.

DK4XL> Elecrafts service is outstanding, no question about it - as long as
you don't ask for QRQ for the internal keyer or improvements of sign
quality and qsk.

Agreed, Elecraft is top notch in all respects, which is why I'm so baffled
by the thought of signal deteriorating above 45 WPM or so.

Since I haven't heard this for myself, I won't put this all out as fact
though.

I'm also wondering if the keyer can be pushed faster without degrading the
signal if you use an external keyer instead of internal, or if you use
non-QSK instead of QSK. Can anyone confirm?
