Mike, It depends on the transceiver that you have. Essentially the up link and down link are using different bands, U and V for example. If you transmit on a V uplink your transmission is transmitted back on the downlink on a U frequency. If your transceiver is capable of duplex operation, you can hear your own transmission on the downlink with a delay that depends on the sat distance from your location. with today's leo sats, it is hardly noticeable. The duplex in the sat communications means that you can transmit and receive simultaneously.
Hope that that clarify. David, 4X1DG ----- Original Message ----- From: Mike To: [email protected] Sent: Wednesday, July 27, 2011 3:25 PM Subject: [amsat-bb] Full Duplex? I'm having a difficult time of understanding the concept of Full Duplex. Can anyone explain it to me? I have the ARRL satellite book, read about it in there and Wikipedia. I still didn't understand how it works with a transceiver setup like we use. Mike N8GBU _______________________________________________ Sent via [email protected].
