SSB-ver-AM
(1) Since the carrier is not transmitted, there is a reduction by 50%
of the transmitted power (-3dBm). --In AM @100% modulation: 1/2 of the power is comprised of the carrier; with the remaining (1/2) power in both sidebands.

(2) Because in SSB, only one sideband is transmitted, there is a further reduction
by 50% in transmitted power (-3dBm (+) -3dBm = -6dBm).

(3) Finally, because only one sideband is received, the receiver's needed
bandwidth is reduced by one half--thus effectively reducing the
required power by the transmitter another 50% (-3dBm (+) -3dBm (+) -3dBm = -9dBm). --Remember, if a receiver's bandwidth can be reduced by 50%: the needed transmitter power is also reduced by 50%, i.e., the receiver's Signal to Noise Ratio (SNR) is improved as the receiver bandwidth is reduced. This of course implies that the signal containing the information is not lost--which is the case in this instance.

Example: A FREEBANDER running 2000 Watts AM, would sound no better than another
HAM running 250 Watts PEP (Peak Envelop Power) on-SSB.

:?: :?: :wink: Lets not forget about selective fading of one sideband of an AM signal causing phase distortion of the audio which is a major reason AM does not work as well in adverse conditions.The narrow the bandwidth the better.
 
thats says it lazybones right there !! :D, its all about conditions plain and simple, i made as many or more contacts that day on 28 am as i did 38 lsb mother nature had her skirt up and i was checking out the beaver !!!

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
  • @ AudioShockwav:
    Wes, it's better if you start a thread on the main forum, more people are going to see your question.
  • @ heartbreaker3473:
    Okay, sorry, will put in a forum
  • @ heartbreaker3473:
    I put it in the general disscution help area and started a new thread. Thank you for letting me know.
