Default Frequency doubling: Is bandpass filtering needed?

HB content: I'm thinking of building one of the little receivers shown
at http://mikea.ath.cx/1-chip-rx.html/, just for hunting QRM.


I like his sentence, "you can do only so much work on a notebook computer with
no reference material around." Wow -- 1997, before ubiquitous high-speed
Internet access (...reference material on pretty much anything you want in
seconds...) in airports was available! And it doesn't even seem that long ago
now!

I suspect taking a radio like that to an airport these days is also going to
get you a lot of close scrutiny going through security... so I like your idea
of using it for QRM hunting.
