Re: Has anyone built Ashhar's Specan?
Maybe switch between the 45khz crystal filter, the 12mhz crystal filter, and analyzing the audio with an ADC.toggle quoted messageShow quoted text

you could just do rms of the audio. the main challenge would be that given 3 khz bandwidth, the 30 mhz scan would need a reading every 1.5 khz. that means, 20,000 readings for the full scan. it will take a long time. this ia why specans have variable bandwidths.
