About “Over the Edge”

Since 1981, Negativland’s live mix, audio collage radio show, “Over The Edge,” has aired weekly for 3 hours at midnight, each Thursday on KPFA 94.1FM in Berkeley, California.

OTE’s themed mixes are made live and spontaneously on the air from a variety of formats and equipment. There is a plan and there is no plan. The mix consists of found sound of many kinds and from many sources put together on the run as the continuous audio collage progresses.

OTE sometimes employs “Receptacle Programming,” which means you. Phone callers are punched into our mix with no warning. Call 510-848-4425 to deposit your programming. When your phone stops ringing, you’re on the air. Don’t say “hello” – just begin.


A 10 to 15 second delay is occurring between our live broadcast and your radio or computer, which makes it difficult to interact with our show “live” on the phone. Turn down your radio or computer and only listen to our real time mix in your phone when calling the broadcast. (Only the little speaker in your phone is getting the show to you at the speed of light.) If you listen to anything else, you will sound drunk. When your phone stops ringing, youre on the air and in the mix.

Extinct Technology:
As many might know, I use broadcast cart machines to mix OTE. This analog bit playing technology is now long gone from broadcasting and everywhere else. Any example of cart players/recorders are automatically old and very used. Repairs are a constant problem (everyone I’ve gone to doesn’t even know what this thing is) and so I’m asking if anyone out there, hopefully in the S.F. Bay Area, is capable of repairing/refurbishing cart machines.

But breakdowns are still a drag, and I’m even more interested in finding NEW or unused machines, if they exist. I’ve searched all over on line, but most all are well worn and the sellers, usually without carts or cables, can’t even test them. Anybody know where new or nearly new, fully operating cart recorder/players might be availble?
Thanks for any help.
