Repeater Duplexer Tuning. Equipment To Tune Duplexers: Receiver, transmitter, sinad, speaker, signal generator, cans. Instructions For Tuning Duplexers: Start by tuning each can separately. ( For initial tuning a handheld can be used, switching between the receive and transmit frequencies.) With a can connected
Some repeater owners attempt to tune their duplexers using the simple method of hooking a couple of radios to their duplexer, using one to transmit and one to receive, and simply tuning for the highest s-meter reading on the receiver for the pass frequency and the lowest s-meter reading for the notch frequency. While this
Duplexer Tuning. I have received several Emails asking for help (or how do I) tuning a duplexer, so I will make my best attempt telling you the methods I and my partners in crime use to tune a duplexer. Before we start with the procedure This article assumes that you do not have access to a spectrum analyzer or a signal
found this design to be extremely difficult to tune, noisy and not all that stable. work as a duplexer. That is, it does not tune sharply enough. Its band pass peak would be too broad, and its notch too wide and shallow. Now a interesting thing .. smartest thing you can do is to contact the manufacturer and buy the manual!
If the tag on the duplexer is still intact, use the original configuration as a guide for determining which way is best for your situation. These duplexers are somewhat asymmetrical. If the duplexer has a label that has the previous frequencies on it (like TX 453.500 RX 458.500), you should maintain the same low-port/high-port
TX RX Systems has excellent instructions for tuning their 6.625" duplexer. **The HP 8920A/B can be used as the Spectrum Analyzer / Tracking Generator and the Amtronix SW2012N as the return loss bridge. There is a section in the Agilent / HP 8920B Applications Manual on duplexer tuning: Agilent / HP 8920B

used as guide lines to determine whether they can be successfully re-tuned and used for a particular application. Test Equipment Requirements. The following test equipment is considered necessary to successful duplexer re-tuning: ? Preferred: A Dynamic Wave Analyzer with dual trace display, 100 dB (or more) in 10.

A duplexer provides the means for simultaneous operation of a mobile relay or repeater station having separate TX and RX frequencies when using a common antenna. •. Page 3. BASIC BAND PASS CONFIGURATION. Page 4. BAND PASS DUPLEXER RESPONSE. Page 5. PASS-REJECT CONFIGURATION. Page 6
