Thanks Stewart. I loaded the latest firmware this morning (I was using 2.20) but before I did that, I tried monitoring my transmitted signal on another receiver, on the same 80m frequency that I did the test with my UK friend yesterday morning. I cannot tell any difference to the keying between having the NR switched in and switched out.
After loading 2.23, my signal sounded exactly the same on my other receiver and a report from a European station on 20m said the keying was "perfect" and there was no sign of any clicks. I now intend leaving well alone and am putting the experience down to one of the mysteries of life! 73 de Chris, G4BUE On 15 Aug 2008 at 2:04, GW0ETF wrote: > > > Don Ehrlich wrote: > > > > I just keyed my K3 with and without NR (all settings) while > looking at the > > keying waveform.
