Andy, thanks for the capture of both my hifers. The upper trace is "SIW" in slash code (upward ramps=dots, downward ramps=dashes). The QRSS6 "SIW" is preceded by a CW ID that runs too close to the first dot in the S. Next time I program the keyer I'll add a delay. -- 73, Garry, K3SIW, EN52ta, Elgin, IL
