Amateur radio folks like building direct conversion receivers (i.e., mix
down to baseband). They're simple, hence little, and they work pretty
well. Their biggest problem is that they have no audio image rejection
at all -- listening with a 7040kHz oscillator, you'll hear a signal at
7040.5 just the same as one at 7039.5.

That's the _second_ biggest problem - the biggest is that they're an
unlicensed transmitter.

Ham radio operators are * licensed * uses of the band from 7MHz to 7.3
Hz - aka the 40 metre band.

In an case, spurious emissions from a flea powered local oscillator is not a
transmitter requiring a licence.

Wot a jerkoff.
