    RW>> Greetings Ed!   
      
    RW> TW>>> I have no problem with that but it stil lstands that the Word   
    RW> TW>>> "Carrier" is a Standard term  used to describe the RF signal   
    RW> TW>>> eninating form a transmitter.   
      
    RW> RW>>> Then how do you explain the non-carrier of a SSB transmission?   
      
    RW> EV>> Howdy! Roy,   
      
    RW> EV>> I learned SSB has a Surpressed Carrier, the Carrier is still   
    RW> EV>> there it's just not at Full Strength.   
      
    RW> EV>> Does that sound correct to You?   
      
    RW>> No. If you do as I have done and key the mic on a SSB xmitter, there   
    RW>> is nothing shown on a Bird wattmeter until you modulate the radio.   
    RW>> Then the wattmeter's needle will bounce up and down, according to   
    RW>> the modulation.   
      
    RW>> So, the carrier that isn't there on key up, might be there in   
    RW>> theory, but it won't be there, even when the xmitter is modulated.   
      
    TW> BUT Roy there are several variations of SSB and NOT all totaly   
    TW> supress the Carrier.   
      
   You're right. There was one CB radio made that boasted Double Side-band   
   and it had a carrier in-between each side band.   
      
    TW> "Reduced-carrier transmission is an amplitude modulation (AM)   
    TW> transmission in which the carrier wave level is reduced to reduce   
    TW> wasted electrical power. Suppressed-carrier transmission is a special   
    TW> case in which the carrier level is reduced "below" that required for   
    TW> demodulation by a normal receiver."

   Tnx for the references. But, in my time here in Fidonet, Wiki isn't   
   exactly a source one can use and depend on, according to those who think   
   that Wiki is written by idiots. I don't think of it that way, but most do.   
      
      
       Have a day!
