     I have a small problem - in buying my own cable descrambler (to replace
the one I rent for $10/month), I'm unable to get a model #/brand - its 
a "black box" with nothing on it. Yet the company I'm dealing with will only
 ship the appropriate unit and won't assist (technically speaking) in trying
 to figure out the type of scrambling. 
     I'm trying to figure out which of the following types it could be:

     1> gated sync
     2> tri/bi mode (Jerrold-type)
     3> SSAVI (Zenith)
     4> vari-sync (Oak)
     5> others:     Tocom/Eagle/Pioneer

     What my cable company does on scrambled channels is "beep-beep" the audio
and cause the picture to flash - which has a strong effect on tuning (hence
the picture jitters). Also the contrast is turned up (not inverted though).
My cable company doesn't like me dropping the lease on their box, so hence
 they won't say anything to what brand they use. I'm hoping to get this solved
so that I can save the $10/month in lease charges.

     Any help's appreciated - please mail me..

                                                  Thanks..
