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 On Mon, Aug 7, 2017 at 9:53 AM, brian <als...@comcast.net> wrote: > I wonder if the QSD keying problems when TXD was set >8 ms has vanished > with the new synthesizer boards? > > It sounds OK in the monitor when using an external keyer at TXD 20 ms.
