[Elecraft] K2 vs OMNI V keying waveform?

Thu May 1 00:30:01 2003

You seldom hear any clicks from any rig when tuned to the signal. Try tuning
off either side 500 too 1000 Hz and listen for keying artifacts there.

My K2 has "hard" keying due to the short rise and fall times which probably
helps in the QRP situation. Frankly, I haven't checked on a monitor receiver
to see how wide the click region is - better do that!
