                        WHAT IS A VIDEO NOTCH FILTER ?                       
                                                                             
     The pictures and  sounds  on  your TV  are carried there by signals.    
     Each signal travels down it's own path, or channel.  A notch filter     
     is used to  block  the  path  of an unwanted signal.  This prevents     
     the  signal  from  delivering  its  information  to  our TV screen.     
     The  filter  acts  as  sort  of  an  "Electronic Roadblock"  to the     
     unwanted signal, while allowing all others to pass freely.              
                           USES OF A NOTCH FILTER.                           
                          (elimination of channels)                          
                                                                             
     This  function  is useful for parental censoring of Adult Channels.     
     Even if  scrambled  by  the  cable  company,  they  may be somewhat     
     watchable.   This  is not the  case when a  notch  filter is  used.     
     The  notch  filter  may  be  used to block the  path of an unwanted     
     channel's signal.  The signal then cannot carry its  picture to the     
     TV screen, and the channel is ELIMINATED.                               
        
                  TO ELIMINATE MILD OR SEVERE INTERFERENCE.                  
                                    
     Interference  occurs  when  some  unwanted  signal  gets  into  the     
     path of the desired signal.   As a result,  both signals  reach the     
     TV screen.  One carries the  clear picture you want, but  the other     
     brings along unwelcome  interference.  A notch  filter  may be used     
     to  block  the  path  of  the  unwanted signal,  while allowing the     
     desired signal to pass freely.  As  a result,  the  interference is     
     removed and all you see is the clear picture.

                            UNWANTED SIGNALS                               
                                                                           
    Unwanted signals may find their way into  your  TV  in  many  ways.    
    Some ways  are  unintentional.   Ham  Radio  operators  create them    
    by using their  radios quite by accident, and there are many  other    
    ways to  introduce  interference accidently. Sometimes interference    
    is put in the path of a signal to block it, as we discussed earlier.   
    In fact, your local cable company probably uses it to block certain    
    channels  they  want you to  pay additional  money to  receive (HBO,   
    SHOWTIME,  CINAMAX,  ect). To remove this interference, they either    
    install a  NOTCH FILTER,  or turn on  the one in your converter box    
    by remote control.

                               THE LIMITATIONS                               
                                                                             
     Notch filters can do many good things,  but there  are limitations:     
     1) they can't fix every type of "interference".                         
     2) It would be illegal to use them to remove the cable company's        
        intentional interference  ( Although they can!! ).                   
                                  THE TEST                                   
   Ŀ  
    The filter CAN allow normal reception of a channel that is presently   
    unwatchable  if ...                                                    
                                                                           
    1) There  is  an unusual pattern  on the screen, which  partially or   
       completely hides the picture.                                       
    2) This pattern looks the same on  the left half of the screen as it   
       does on  the  right  half, at all  times (Zig zag lines or snow).   
    3) The  patern is  accompanied  by an unusual sound.  This sound may   
       be a  humming, buzzing,  shrill,  alternating,  or garbled sound.

    1) Determine  the  channel  number  that  you wish to block or clear.    
    2) Make sure it meets the requirements  of the test  or write or call

All filters are made from top quality parts and are tested before they are   
shipped to you.  I have ordered filters like mine from many other companys   
and I found them all unacceptable, with only one acception, the picture was  
grainy (bad).  My filters deliver fantastic picture quality because I use    
top quality parts in them.

plastic enclosures.  Tuning instructions and tuning tool included.           
                                                                             
DELUXE FILTERS- Are made with Air Dielectric tuning and multiple turn fine

tool included.                                                               
                                                                             
KITS- Include all parts including printed circuit board to assemble a NORMAL 
FILTER.  Tuning tool and instructions included.  Some knowledge of basic     
electronics (soldering) required.

TUNING TOOL- Basically a plasic screwdriver.  (It's good to have a spare one)
                                                                             
                                   NOTE:                                     
Filters work on one channel at a time and must be tuned for each new channel.
If you have a  converter box (NOT A VCR) all you will need is F111. F111 will
clear multiple  channels  with a converter  (IT WILL NOT WORK WITH A VCR!!!).
Using any tuning tool other  than the  CAT#  T1  may result in damage to the 
filter.
