Re: [Elecraft] K3/K3s keying with bugs, ponderings

Hi Roy, A question best answered with a measurement. Appended to: https://www.kn5l.net/debounce555/ is waveform for a Bug running just under 40WPM. One small weight at fastest setting. John KN5L On 5/10/21 11:17 AM, Roy wrote: > Relating to contact bounce, I wonder what the typical length of a

[Elecraft] K3/K3s keying with bugs, ponderings

Relating to contact bounce, I wonder what the typical length of a bounce is? We hear QRQ stations operating at 60+ wpm all the time. If Elecraft designed to smooth out such short "dots" from semi-auto key bounce, then perhaps a K4 would not allow 70+ wpm speeds to be sent either? 73,  Roy
