Hello group, I doubt if I invented this, but here is a fool-proof method of zero beating:
I start Spectroscope which has been set to display a frequency mark at 540 Hz (my preference). I then drag it over to the right side of the screen, leaving room for HRD on the left. As I tune, I simply bring the peak of the desired CW signal under the 540 mark and I am dead bang on. Of course I must also set the sidetone on my K2 to 540. BTW, I found a free program for my PDA that registers the frequency of a tone. Find a steady tone, somewhere (birdies are ok) and tune it untill it is loudest - that's your ear's sweet spot. Measure the frequence, set the K2, set spectroscope, and away you go. 72/73 Tom, ng3v (on cw since 1958 and enjoying it more every year) -------------- Original message -------------- From: Lee Buller <[EMAIL PROTECTED]> > > The Auto-Spot feature is very cool and has been excellent for me.
