Hi Eric, Still just playing with it,I'm Hoping the FFT ,will allow me to see the response of some filters, for a receiver I've been building. these days I prefer to build my amateur radio equipment rather than buy it,It's funny how it works out, when I first got licensed I had no skill and no money, and it took ages to buy anything, now I have some skills, and got the money to buy amateur radio equipment , I'd much rather build it, life's a strange beast.
