I use the 6ms setting on my IC-7610 and IC-7300 feeding an ACOM amp and am able to uphold a friendly coexistence with my neighbors SA7JMA and SA7BKX 400 and 900 yards away, respectively. It may howev

Hi John, Look up "key clicks" in the index of your ARRL Radio Amateur's Handbook or read George Grammer's excellent article in October 1966 QST: p1k.arrl.org/pubs_archive/54578 or W8JI's article here

I was alerted that my K3S was generating a bit of crap that sounded like hot switching the amp. It turned out that the default TX Delay setting of 008 was a tad too short. Changing it to 009 resolved

Hi Art, Well designed radios will not have a problem with 6 msec rise times using the highest CW speeds in use by contesters. YMMV with radios with design inadequacies. 73 Frank W3LPL -- Original Mes

Rise and fall times dont tell the whole story. It also depends on the SHAPE of the rise and fall. The cleanest modern radios use their DSPs to produce nearly optimally shaped rise and fall. (Theres m

You want to be careful using too large a value for TX DLY in the K3/K3S. Making the delay longer shortens the duration of transmitted dits and dahs, and can make the CW sound "choppy", especially at
