At a workshop in Brno a few years ago a student brought in a "Neywa"
Russian radio to hack. It sounded great to my ears, but he was ambivalent enough about it to trade it to me for a copy of my book. I dug it out a few months ago. Outside of the noisy workshop space the radio proved ridiculously loud and shrill, so I disconnected its tiny speaker and hooked up one I'd salvaged from our old teardrop iMac before it went to recycling. This gave a nice bass boost, and the speaker can be muted and filtered with the hand or resonated with one's mouth -- a sort of a marching band crackle box (CrackleCornet?). The red wire with the faston terminal is a replacement antenna. The road case is a Nicaraguan cigar box.
