      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 there       RW> EV> 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 is       RW>nothing shown on a Bird wattmeter until you modulate the radio. Then the       RW>wattmeter's needle will bounce up and down, according to the modulation.              RW>So, the carrier that isn't there on key up, might be there in theory, but       RW>it won't be there, even when the xmitter is modulated.              BUT Roy there are several variations of SSB and NOT all totaly supress       the Carrier.              "Reduced-carrier transmission is an amplitude modulation (AM)       transmission in which the carrier wave level is reduced to reduce wasted       electrical power. Suppressed-carrier transmission is a special case in       which the carrier level is reduced "below" that required for       demodulation by a normal receiver."              Ref - http://en.wikipedia.org/wiki/Reduced_carrier       ---        þ SLMR 2.1a þ Typo Tom Strkes Again        * Origin: TECHWARE BBS - Since 1995 - www.techware.dynip.com (1:102/401)    |
