K3 keying

[Barry Simpson]

No one has commented on the apparent shortening of the first dit  as illustrated in the QST review, Figure 1.

 

My K3 keying does not have that issue as far as I can judge from listening on a separate receiver.

 

What is does have is a disparity between keying weighting between MOX (either front panel switch or foot switch) and VOX/QSK.

 

Compared with MOX which has characters about the same length as my other rigs on my keyer’s 50% weighting setting (ie it is about right) the characters in VOX and QSK are shortened.

 

I simply overcome it by altering my weighting to 58% and not using MOX. I note that Elecraft deal with the same issue by having the weighting set at 1.15 in the config menu.

 

Not a real problem – just an observation.

 

Looking forward to giving the K3 a good workout this weekend.

Barry,

Shortening of characters in QSK is a common issue in many transceivers though it seems less of a problem in the K3. What you should really use to combat it is 'Keying Compensation' which you will see in for example Winkey configuration settings and other external keyers; it lengthens each character by a fixed amount (x millisecs) and is independent of keying speed and is designed specifically for this problem. Think I'm right in saying the K3 internal keyer doesn't have this adjustment (yet?).

When I checked my K3 on my 'scope the shortening in qsk looked pretty minimal but I find a setting of 3ms makes the (Winkey) keying feel 'sweeter' so that's what I use...

73 and look out for you this weekend at GW0GEI (M2)
