Newbie Tone Question

S

New member
I have read the manual and think I have a fair understanding of how the 3-Tone and 4-Tone modes work. However I don't understand why the specific tone frequencies were chosen for the built-in programs. For all but one program (dry beach), the frequencies are 202, 518, 644 and 757 while the allowed frequency range is 200 - 791 Hz.

First, why 202 - why not 200 and why 757 - why not 791? Are there issues choosing the extreme limit values?

I understand wanting a relatively large jump between ferrous and the first non-ferrous band so (202 - 51:geek: to make the ferrous sound distinctly different from non-ferrous. But why not divide the remaining frequency bands up evenly (518, 644, 757)? Currently they have differences of 126 and 113 Hz separation.

Anyone have a clue? And yes, I realize that I am questioning something that in the end probably does not affect anything really. Its in my nature to question things though!!!

Thanks
Barry
 
Hi Barry,

Welcome to the forum. You will find answers to almost all of your questions here.....very helpful folks.

Thanks Welwood, once you pointed out that specific frequencies could not necessarily be selected I did some investigating on my new machine. I found that the answer is a little more complicated than the answer you were given in that thread. They said the numbers change by 3 with every press of the '+' or '-' button. On my machine, each button press changes the value by a varying amount. At the bottom of the range (200 Hz) it changes by 2 or 3 and at the top of the range (791 Hz) it changes by 9 or 10. In the middle of the range it changes by something between 2 and 10 depending on where you are within the range. All of this makes no difference to the use of the machine but I like to understand these details. HH
 
Thanks to you Barry,

If you hadn't dug deeper, I would have continued on my merry way not understanding/knowing the total picture.
Aren't these forums great for learning about our great hobby. GL&HH
