Re: Why wasn't there ever a VHS based consumer audio format?

If that succeeds then I bet I'm into something.The squawking you hear when modems connect is them testing the line and agreeing between themselves on equalisation and modulation settings. They can't do that with tape record / replay. Modulation schemes for tape necessarily differ from "line" schemes.
