[Elecraft] K3 keying

[GW0ETF]

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)
