Working on a recalcitrant amplifier I noticed dot length differs between PTT and QSK. I measured 32ms QSK, 38ms PTT at 40WPM using the internal keyer. Without the amp. Is this a feature, or a problem? S/N 2217 -- 73 Art K6XT~~ Success is going from failure to failure without a loss of enthusiasm. ARRL, GMCC, CW OPS, SDDXC, NAQCC ARRL TA
