[Elecraft] QRQ QSK - specs?

[Chester Alderman]

Bruce - John - Terry,

Bruce, no problem on signing the post, I just wondered who I would be
talking with!!

I used to be very active with a small QRQ group of hams in which we would
typically have QSO's over 100 wpm and sometimes as high as 125 wpm.

I, in the past month, have tested my K3 s/n 8895, tested into a dummy load
with full QSK. I believe Elecraft specifies full QSK at 100 wpm, but I could
never get it to go that quick and at about 95 wpm, characters would start
losing spacing and weight settings. However with the installation of the new
synthesizer boards and the firmware upgrade, I was able to test my K3 at
between 115 wpm and 120 wpm. Meaning I could copy the characters at those
speeds. Above about 120 wpm, the spacing and weight issue crept in again. I
would feel very secure in recommending the K3 (and probably) the K3S
operating full QSK at 120 wpm and we really could not ask for anything more
than that! 

At one time I owned an original Orion and the Orion II, neither of which I
could use for QRQ; back then when I was doing QRQ I would use a modified
Omni 6+ and if I wanted to run over 90 to 100 wpm, I would use either an
IC-781 or an IC-7700. Now I am more into contesting simply because the old
QRQ group dissipated, but in my opinion, my K3 is really great for operating
in a high signal environment and the high speed full QRQ is just an added
plus!

I hope this info helps some.

73,
Tom - W4BQF

 Anyone know? - Does Elecraft
 offer any specifications for QSK performance?
 Perhaps some sort of T/R turnaround time or a  claim for some max. WPM with
acceptible  performance?
 I've been in discusions
 with some friends that do QRQ QSK with K3's and the  K3s - seems to be some
slight  disappointment.
 No problem for me - But I
 have noticed that my Orion II seems better than my
 K3 (with the new Synth) in QSK...
 Anything official on this?
