electronic pitch source

Hi Ed,
Yes, I use the f2 test for the fork. I find that f3 doesn't work that well fo rme anyway.  I was taught to use f3 but I already knew about the f2 test from seeing Jim Coleman do it on the Randy Potter video.  

Speaking of test, how you test octaves when you get way up in the trebble?  Do you use 17th exclusively, or is there another test I could use?  I know that for 4ths the third sixth test works and for 5ths, the major third minor third works, minor third is the first and major is the scond interval.  They are to beat at the same rate I think. Is that correct?
