Does anyone know of some active Usenet newsgroups (/Google groups) which are relatively spam free?
I have, literally, seen only comp.dsp and comp.arch.fpga survive, over the last decade or so, and my searching skills are borderline garbage.
My interests are mostly in physical-layer signal processing and implementation, rf measurements, and the occasional microcontroller based designs.
Would really appreciate if someone could point out some other active (and by active I mean having some real, relevant, and a large number posts and replies) groups.
Or has everyone moved on to forums like EEVblog and EDAboard ?
