Re: Antuino 2.0

Still working on the code, but I was able to borrow a 72db step attenuator from a fellow ham.  With Bruce Hall's (bhall66)'s improved code, my Antuino is showing pretty good linearity (in my opinion).  I'm pretty sure I'm having more issues with the attenuator (as it is a slide switch design) providing consistent attenuation than issues with the Antuino.
