Re: Has anyone built Ashhar's Specan?
The 45mhz crystal filter is likely rather narrow as well.toggle quoted messageShow quoted text
Perhaps have an option to replace the 45mhz crystal filter with something like this: http://www.mouser.com/ProductDetail/Murata-Electronics/PX1002/?qs=Xb8IjHhkxj400FumWvF4dQ%3D%3D
Mouser summary says it's 25khz wide, but datasheet says the 3db passband is typically +/- 25khz from center, so 50khz wide.
Don't have to stuff this sort of thing on all uBitx boards, not everybody will want a spectrum analyzer.
But would be nice if it was easy to hack in, with pads on the board for the PX1002 and AD8310.
