Paul and all, Another way of investigating is with a spectrum analyzer - and for investigation of a transmitted signal on one band, it does not have to be expensive (but must be homebrewed to be inexpensive). See the implementation by G4AON at http://www.astromag.co.uk/ssa/
It is quite a nice narrowband spectrum analyzer - you can see the display using Spectrogram or Spectrum Lab or most any other audio spectrum analyzer running on the shack's soundcard equipped PC. You are correct, a 'scope is the most useful tool for measuring timing and amplitude. 73, Don W3FPR On 12/3/2010 10:55 AM, Paul Christensen wrote: >> Why, yes IMO the K3 clicks too much. > Jim, > > If you're experiencing clicks with your K3, you really need to investigate > with a scope.
