Good point, Peter,
I've noticed a growing number of key klix on 160m, but never jumped to
conclusions, feeling that my receiver might be the reason because there's
also a growing number of strong signals on the band.
When viewing some of those fast rise/fall time CW keying waveforms in the
QST reviews I often wonder if the rig would produce klix. A notable
example is the keying waveform of the FT-1000MP (figure 2, page 71, April
1996 QST). The first dit looks click-producible, the second dit, maybe
not.
Perhaps other Topbanders might want to comment.
