Hi Kevin, WB5RUE. My experience beginning from OSCAR-6 suggests that Full Duplex is really required and not only an option because the first requirement to succesfully access a satellite transponder is to hear your signal coming back to your receiver.
If you are able to hear back your signal than any other satellite station with a similar set-up is potentially able to hear him self and contact you. Your set-up using a separate TX and a separate RX seems to be just it is necessary for a good satellite operation. 73" de i8CVS Domenico ----- Original Message ----- From: "Kevin Muenzler, WB5RUE" <ke...@eaglecreekobservatory.org> To: <amsat-bb@amsat.org> Sent: Thursday, February 07, 2013 9:33 PM Subject: [amsat-bb] Re: Getting back into Satellites > 73/all > > Is Full Duplex really required or just nice to have?
