It doesn't sound like you really know how to use gentoo based on what you're saying. I've built KDE and a system from scratch and it doesn't take one day let alone three. Also, don't set USE flags system wid unless you know you want to, that's what /etc/portage/package.use is for. And by the way, there's no newuser switch, it's newuse, as in new use flag.

Don't bash it just because you can't take the time to read the handbook and figure out how to use it.

Gentoo's not for everyone, certainly not you.

All recent RF chips for wireless are zero IF nowadays.

Not true, super heterodyne is still very popular.

A SDR approach will use a big DSP (vector DSP even) to do the processing in software.

Not really. Depending on your platform the industry trend is actually going away from DSPs. DSP operations are being implemented in FPGAs these days (since they're faster and the newer Virtex 6 or 7s (and whatever Stratix whatever) are really huge).

You're just talking about different receiver structures (super heterodyne and direct conversion respectively). There's no receiver structure that's specific to SDR (in fact the USRP, which is an SDR, has a super heterodyne structure). IQ sampling doesn't have anything do with receiver structure either, super heterodyne receivers and direct conversion receivers can have IQ sampling (the USRP, a super heterodyne as I mentioned, implements IQ sampling). Also, implementing a filter with a sharp transition band is due to using a digital system, there's nothing special about SDR that let's you implement a 500 tap FIR filter, there *is* something special about digital system (FPGA, ASIC, DSP, GPP) that let's you implement a 500 tap FIR filter.
