It is the pass frequency. ----- Original Message ----- From: George Henry To: repeater-builder@yahoogroups.com Sent: Tuesday, July 10, 2007 8:56 AM Subject: [Repeater-Builder] Notch duplexer dumb question
I have a Motorola TDN7407A notch duplexer (in reality, a Motorola-branded Celwave 633-6A-2N) that I want to use for a low-power GMRS repeater. The ports are labeled HI and LO.... now for the dumb question, do those labelings refer to the NOTCH frequency or the pass frequency? Unfortunately, it is not labeled with the current tuning, and I don't have easy access to anything to sweep it with.... George, KA3HSW / WQGJ413
