[Elecraft] K3 performance - soft keying and linear key output

[Dave G4AON]

I've just done some measurements with my K3... CW waveform rise and fall 
times are both 5 mS (and doesn't alter when the speed is changed with 
the internal keyer), which some would consider a bit soft - although my 
measured bandwidth for 20 wpm keying at 100 Watts of RF is +/- 500 Hz at 
70 dB below peak output, which is probably as clean as it gets. The time 
delay between the linear keying line going low and RF appearing from the 
antenna socket is 10 mS.
