Re: Has anyone built Ashhar's Specan?

An ADC on the audio with a simple program to do peak detection might do about as well as the ad8307 on the 12mhz IF.
But the ad8307 will give better dynamic range (unless you have an awfully nice ADC),
and the ADC would give the possibility of doing an FFT in software for very fine grained resolution.
I think.

Maybe switch between the 45khz crystal filter, the 12mhz crystal filter, and analyzing the audio with an ADC.
