Last time I looked at Waddle K. Knowitall's Authoritative Real Meanings Dictionary, 70 wpm, indeed 50 wpm was QRQ all the way.
If you want QSK, you should set the TX DLY to minimum 8 and leave it there forever. I don't like the way it behaves at higher delays anyway. If you want to keep RX from opening in certain contesting situations, do it with the logging program and it's PTT setting and pipe the logger supplied PTT signal around. You will find that your 9500 and the K3 are slick together. You CAN use the CW+ fast QSK, but this is a fight in the K3 against RX-TX-RX transition tasks. e.g. CPU time in the firmware, and in order to be really fast some functions are disabled. You will need to decide if the disabled functions are things you can do without. 73, Guy.
