Ah, the RHV technology changes. From an old Gates Studioette (actually a Yard, cut down) which occasionally smoked (it was old enough) to some RadioShack stuff to a Mackie 10-channel mixer. Inserts via MiniDisc, as nobody is actually in the studio when I record it; they are all pre-records; once in a while someone might be with me, but that's unusual. Features are all on CD's.
I'm a stickler for timing (just for myself, not for fill-in directors). One day, when we were on reel and taking ABC-I net, some "done ten shows" freshman was there when we were on the take-out and said, "You're going to run over." Dumb sh*t. I waited for the 10-second warning tone, turned up the net pot, then stood back at the door. "...community service of King's College. BEEP. (sounder)." To the kid: "I don't run over."
During the latter cassette days, the late Sherwood Baker and I used to have a contest to see who could switch the cassette the fastest. Stop tape, eject, insert, hit play. I think the record was something like 2.5 or 3 seconds.
We're on MiniDisc now and life is much better. However, these little squirts have a tendency to start a new track if there is more than a second of dead air, so the challenge now is to do a 60-minute program in one track. It makes absolutely no difference on playback, but it louses up the disc timer, as I like my 60-minute program to be 60:00 minutes long and I'm rarely off by as much as a second. Have gone months without running under or over by that much. Just a personal quirk.
btw: When I was on network affils, I never once upcut the net, nor was there dead air ahead of it.
