Greetings TOM!   
      
    RW> TW>> The Digital sub channel, SD6, on their carrier does not use

    RW>> Carrier?   
      
    TW> Standard term for an RF signal transmitted.   
      
   I was unsure about the use of the word, but pretty sure that you didn't   
   know what you're talking about there.   
      
   A carrier is an alternate system that 'carry's' a station, such as cable   
   or sat services. Also note below where it says: "individuals or companies   
   that authorize broadcasting or other use of radio transmissions in   
   connection with broadcasting"   
      
   //Quote   
      
   FCC Authorizations (as required by 73.3526(e)(1), 73.3527(e)(1)) (retain   
   until replaced). These are the instruments issued by the Commission to   
   individuals or companies that authorize broadcasting or other use of radio   
   transmissions in connection with broadcasting and include licenses and   
   permits to construct or modify broadcast facilities.   
      
                          Station Identification.   
      
   Stations must air identification announcements when they sign on and off   
   for the day. They also must broadcast these announcements every hour, as   
   close to the start of the hour as possible, at a natural programming   
   break. TV stations may make these announcements on-screen or by voice   
   only. Official station identification includes the station's call letters,   
   followed by the community specified in its license as the station's   
   location. Between the call letters and its community, the station may   
   insert the name of the licensee, the station's channel number, and/or its   
   frequency. It may also include any additional community or communities, as   
   long as it first names the community to which it is licensed by the FCC.   
   DTV stations also may identify their digital multicast programming streams   
   separately if they wish, and, if so, must follow the format described in   
   the FCC's rules.   
      
   //Unquote   
      
   This would apply to "SD6" when it broadcasts to it's TJ location via US   
   based studios in San Diego. Those xmitters have to be licensed to operate   
   under the jurisdiction of the FCC.   
      
    RW>> Whatever their FCC issued license for their sat link is, they do. It   
    RW>> is included with their uplink signal and is digitally IDed.   
      
    TW> I am not talking abolut any Sat Link but direct transmissions form   
    TW> hte statio non their Assigned Frequenct.   
      
   How can you talk about it when you can't get the station over the air?   
      
   Sure, you get it on Cox, which is under the "Must-Carry or Retransmission   
   Consent Election" of the FCC rules.

   "Must-Carry or Retransmission Consent Election. The public file for all   
   commercial television stations must also contain documentation of the   
   station's election for carriage over cable and satellite systems. In this   
   regard, there are two ways that a broadcast TV station can choose to be   
   carried over a cable or satellite system: "must-carry" or "retransmission   
   consent." Each is discussed below.   
      
        Must carry. TV stations are generally entitled to be carried on cable   
        television systems in their local markets. A station that chooses to   
        exercise this right receives no compensation from the cable system.   
        Satellite carriers may decide to offer local stations in a designated   
        market area. If they choose to offer one station, then they must   
        carry all the stations in that market that request carriage.   
      
        Retransmission Consent. Instead of exercising their "must-carry"   
        rights, commercial TV stations may choose to receive compensation   
        from a cable system or satellite carrier in return for granting   
        permission to the cable system or satellite carrier to carry the   
        station. This option is available only to commercial TV stations.   
        Because it is possible that a station that elects this option may not   
        reach an agreement with the cable system, it may ultimately not be   
        carried by the system.

    TW> Within their Frequenct allocation they are transmitting two signals.   
    TW> The main signal is in Spanish and the other one is in English. They   
    TW> are two different signals eminationg from two different studios.   
      
   Everyone knows what 'secondary audio' is...   
      
    TW> It is possible to have up to 12 different signals within the same TV   
    TW> channel allocation.   
      
   Not on an analog station.   
      
    TW> The more channels of course means lower broadcast quality. Here is a   
    TW> bit form the Internet:   
      
    TW> Trinity Broadcasting Network stations has five SDTV channels, the   
    TW> most of any large broadcaster in the country.   
      
   We have the same 5 Trinity channels in San Antonio...now what?   
      
   PS - One of the new rules I'm going to implement in next weeks posting   
   will be a clause that requires anyone who plagerizes information from the   
   internet must provide a 'working' link to that information, using //Quote   
   and //Unquote (and the author's name if available) before and after that   
   information. Using " " won't cut it.   
      
      
       Have a day!
