So...what ever happened to this? has anyone confirmed that pre FM King Biscuit reels were actually 4-track quad, not SQ matrixed 2-track? This is startling news if so, has it become accepted fact since 2015...?
Given the number of fan and bootleg releases over the years of some of these broadcasts, claimed to be sourced from preFM reels, it seems extremely odd that no one would have noticed that they were only hearing the front two channels (even if 'decoded' into 4).
Have any of these discrete (not matrixed) quad reels been verifiably transferred to digital, and are out there in the community as discrete 4 channel files/discs?
because I'm still seeing (this year) new *decodes* being created/offered for KB shows, sourced from "Pre-FM SQ encoded broadcast reel "
