   RW>Carrier?   
      
   Standard term for an RF signal transmitted.   
      
   RW>Whatever their FCC issued license for their sat link is, they do. It is   
   RW>included with their uplink signal and is digitally IDed.   
      
   I am not talking abolut any Sat Link but direct transmissions form hte   
   statio non their Assigned Frequenct.   
   Within their Frequenct allocation they are transmitting two signals. The   
   main signal is in Spanish and the other one is in English. They are two   
   different signals eminationg from two different studios.   
   It is possible to have up to 12 different signals within the same   
   TV channel allocation. The more channels of course means lower broadcast   
   quality. Here is a bit form the Internet:   
      
   Trinity Broadcasting Network stations has five SDTV channels, the most   
   of any large broadcaster in the country. Smaller stations, willing to   
   compromise on broadcast quality, have been able to fit many more   
   channels into a space. KAXT-CD in San Francisco is believed to have the   
   most feeds of any individual over-the-air broadcaster, with twelve video   
   feeds (all SDTV) and several audio feeds (WANN-CD in Atlanta, Georgia,   
   with ten video and six audio feeds, comes in close second); several   
   cable-to-air broadcasters have (such as one in Cortez, Colorado)   
   multiplex more than five separate cable television channels into   
   subchannels of one signal.
