Okay - that makes sense... in terms of azimuth adjustments I suppose. I
had the impression that one could use a scope to more rapidly determine
the correct bias setting. Would this be wrong? My impression was that
you would compare the raw tone from the generator with the PB tone on
the scope and this would tell you when you were on the mark. I could be
WAAAYYY off here - but this was my impression. Is there no way around
having to use an MRL tape?
