As John points out, QRSS3 mode would make screen captures practical. Although Argo has an NDB mode that can be used to display normal-speed CW, it takes only 34 seconds to fill the screen. Continuous time coverage would require 1271 captures in a 12-hour session! So I'd recommend either straight QRSS3, or QRSS3 alternating with a 6 WPM or 12 WPM identifier. Lyle, K0LR
