At least for CW, I think the worst is now behind us. Also, some of the worst offending transceivers are manufactured for the high-end HF commercial and military markets. Within the last few years, manufacturers in the amateur market have paid better attention to the shape of the keyed envelope. Even Yaesu's newest transceivers are reasonably good. The usual culprits are now out of production, although they will continue to show up on the air for a long time. Start handing out 599K reports to the remaining offenders. > Whats amusing is that everyone focuses on keyclicks, yet the problem > exists to a greater degree on SSB. Agreed and that's the next opportunity for improvement. IM effects from transmitters that are only -30dB (I3), can not only be heard, but are clearly visible on a direct-RF-sampling pan adapter. I would like to see I3 improvement to at least -40 dB, and -55 dB is now attainable with pre-distortion techniques like that used on the Swiss ADT-200A. Those numbers are repeatable across bands and the '200A does not reply upon an ATU to get there.
