Greetings TOM!   
      
    RW> TW>> Within their Frequenct allocation they are transmitting two   
    RW> TW>> signals. The main signal is in Spanish and the other one is in   
    RW> TW>> English. They are two different signals eminationg from two   
    RW> TW>> different studios.   
      
    RW>> Everyone knows what 'secondary audio' is...   
      
    RW> TW>> It is possible to have up to 12 different signals within the   
      
    TW> same TV RW> TW> channel allocation.   
      
    RW>> Not on an analog station.   
      
    TW> I am not talking abuut secondary Audio but Multiplexing of TV signals   
    TW> on a digital Tv Transmitter.   
      
   That's what I said.   
      
    RW> TW>> The more channels of course means lower broadcast quality. Here   
    RW> TW>> is a bit form the Internet:   
      
    RW> TW>> Trinity Broadcasting Network stations has five SDTV channels,   
    RW> TW>> the most of any large broadcaster in the country.   
      
    RW>> We have the same 5 Trinity channels in San Antonio...now what?   
      
    TW> IF they are multiplexing you can get more than 5 TV signals from   
    TW> those 5 transmitters.   
      
   Doubt it. That would be pushing the envelope too far and they'd be   
   xmitting out of their allocated band frequency. As a HAM or HAM advocate,   
   you should know that the very idea of xmitting on the edge of a band will   
   get you in trouble with the FCC.   
      
      
       Have a day!
