Re: Auto-Spot Feature and Hearing

[ng3v]

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)

If using this in a contest you will have to make sure your filter passband is quite
narrow.  If there are multiple signals within the passband it will not know which
signal to tune to.

Yes, I bet that if you use that during the contest...you will have issues with auto spot.  I just haven't had time or a contest to enter to see what would happen.

In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?
