/accu pick up

[D.Martens]

It is indeed important for electronic clocks.
( if I'm correct , there's two ways to calibrate tunelab : manually, by
filling in a number, or calibrating using the computer's clock. I feel
better with a manually calibration)

Wether it's 59 or 60 Hz, the noise is still  there, causing problems with
the accu pickup.
