<---Why wouldn't it work for transmit? As a matter of fact, it would work just fine by both the receive AND transmit sides of the duplexer. RF is RF, regardless if its -100 Dbm or +10 Dbm, right? Depending on what kind of duplexer is it (BP/BR or just BR) determines the tuning procedure. You might want to check the website to see if yours is listed. One thing though - It's a good idea to use a 3 db pad on the receiver you're using for tuning, since you have no guarantee it will present a 50 ohm load to the duplexer. Oh, and don't forget to make sure a 50 ohm load is on the duplexer port not currently being tuned as well (a 3 db pad would work here as well).
