A standard procedure to set up antiskating is as Dave Martindale
mentions would be to play successively higher record signal
modulations until mistracking does not occur. An algorithim
for this might be as follows:

      1) Select a modulation level representative of the records
         you use. (ie. Telarc records are more difficult to track
                       than 22 hists/side K-tel specials

      2) Have the above in some sort of sinusiodal test tone form for
         ease of alignment (distorted sinusoids can be percieved
                             with wads of cotton stuffed in your ear)

      3) if distortion occurs on both channels then increase tracking force
         until one of channels tracks.
      4) if distortion on right channel > left channel decrease skating
         until roughly equal. And vice versa for the converse situation.
         repeat 3)

  The aim is to track both channels equally, while at the same time
  to provide minimum tracking force requirements for minimum wear.



  The underground has it that cartridges sound best at around this state,
tending to go murky with to much stylus force.  The sad truth is
that the 'goden ear' maintain that the above algorithim does not
produce optimum sound. So much for trackability factors.
