[Elecraft] TXD QSD fixed?

[Bob Wilson, N6TV]

Setting CONFIG:TX DLY to 20 ms will shorten the first element (dot or dash)
by 20 ms (about).  If you're using QSK, it will shorten *every* dot or dash
by that amount.  The new KSYN3A synthesizers do not change this.  Setting
CONFIG:CW QRQ ON will make the TX delay much shorter (how much shorter is
not well documented, but it is significant).

The length of a dot, in milliseconds, is 1200 / speed in WPM.  So at 40
WPM, a dot is only 30 ms long, and you'll be removing 2/3rds of it with TX
DLY 20 (but you may not hear this in the monitor).

What amplifier are you keying with the K3 that requires such a long TX
Delay to avoid hot switching?

73,
Bob, N6TV
