Also, a reminder: this is nothing new. We’re just clarifying a delay offset that has existed for a long time. There have been no recent firmware changes.
It would be possible to modify the K3’s keying algorithm to allow for much longer delays (say, 0 to 200 ms). Of course this would significantly shift CW RF output in time relative to keying input. Fortunately, very few amplifiers require more that a few ms of extra delay. 73, Wayne N6KR ---- http://www.elecraft.com > On Jun 8, 2018, at 7:33 AM, Wayne Burdick <[email protected]> wrote: > > The delay can be set from 8-20 ms at present.
