    "content": "Hi Mike,\n\nOthers have answered the question quite well.  One additional point I'd like to \nmake is how important it is to actually listen to your yourself on the downlink, \nfor a couple reasons.\n\n1. On an FM bird, if you can't hear yourself or you hear a double... Stop \ntransmitting\n2. On a linear transponder (CW, SSB), use only enough uplink transmit power to \nbe heard on the downlink.\n\nFor #2, the rule of thumb is to compare your downlink signal strength to that of \nthe satellite's beacon and adjust your uplink power so your downlink does not \nexceed that.  A satellite PA can only put out so much power (say 1W).  So if \nyour uplink is 20 dB stronger at the satellite than anyone else's, your downlink \ncould be transmitted at .99W leaving only 10mW for the rest of the QSO's in the \npassband.\n\n73\n\n \nJohn Belstner W9EN\nValley Center, CA  DM13le\n\n\n\n\n----- Original Message ----\n> From: Mike <[email protected]>\n> To: [email protected]\n> Sent: Wed, July 27, 2011 5:25:49 AM\n> Subject: [amsat-bb]  Full Duplex?\n> \n> I'm having a difficult time of understanding the concept of Full Duplex.
