   Greetings TOM!   
      
    RW> TW>> Well there are stations doing it. Both Ch 8 & 10 here trasnmit   
    RW> TW>> additional TV signals in addition to their Main Programing.   
      
    RW>> Well, you do know that they don't transmit that programming on the   
    RW>> edge of their allocated bandwidth, don't you?   
      
    TW> i NEVER said NOR implied that.   
      
   You didn't have to. It was clear that this is what you meant.   
      
    TW> IF you would go back you would see I said the main channel definition   
    TW> had to be reduced IF subchannels are transmitted   
      
   Not correct for a digital signal. The same (6MHz) bandwidth is used for   
   digital information as was used for the old analog information. The big   
   difference is that a digital signal is compressed, both in picture and   
   sound. Thus the ability to add 4 digital channels in the same bandwidth.   
      
   Adding a 5th channel requires even more compression, which only serves to   
   reduce the picture and sound quality of all 5 channels. Instead of 1080   
   lines, you get 720 or even less. The less lines you have, the less pixels   
   you will get.   
      
       Have a day!
