Re: [ARSCLIST] Tape Speed resolver question

[Bruce Maddocks <bruce@xxxxxxxxxxxxxxxx>]

Goran,

I wish it was SMPTE. But there is not a hint of it in this tone.

I even looked around the "dirt" below the 3khz peak hoping to find a
60hz component I could grab, but it was just noise and "junk".

Thanks for the link, I'll add it to this research.

Cheers!

Bruce
