As a young child, I would hide under the table when Roger came around. Later, when I first started in electronics, he gave me a bunch of parts, tools and bench equipment. Controls interfere with demodulation accuracy resulting in familiar yet unexpected signal degradation and noise. Decoherence at its finest.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTUNE\u003c\/b\u003e:\u003cbr\u003eLike turning the dial on your receiver, the TUNE parameter sweeps through a wide variety of sounds.
