TUNING INSTRUCTIONS. The units are normally supplied tuned to the desired frequencies and no. readjustment should be required unless there has been a change in frequency. The following equipment will be required to tune the duplexer: l. A 50 ohm signal generator with variable attenuator which covers the desired

22 May 2011 I've got a Celwave 6-cavity Bp/Br duplexer, equivalent to the Phelps Dodge PD526. This one actually has a Motorola part number on it: 0185417U05 and it's the same one they use with Quantar and MTR2000 systems. It uses RG400-size coax and looks to be in very good condition; very few scratches.
From the amount of questions we have received on the web page, I saw a need for an article to demystify the subject of duplexers and cavity filters. Duplexers and their cousin the Diplexer (note they are not the same thing) are electrically simple filters. They allow us to transmit and receive on the same antenna at the same

Understanding, Maintaining & Re-Tuning Antenna Duplexers. A band pass duplexer using six band pass type cavity resonators is shown in schematic form in Figure 1. Note that each branch has three cavities connected together with cables. A. “tee" junction and two more cables connects the two branches with the antenna

The receiver port is tuned to the transmitter frequency, which it notches out. Notch only duplexers are readily available in the used / surplus market and eBay is also a good source. These were commonly used in mobile repeater applications and were made by Celwave, Phelps Dodge, and others. When the duplexer has the
18 May 2009 Does anyone know where I can pick up some specs on this unit, perhaps a PDF of tuning instructions? From what I can tell from the construction, it seems to be a notch style duplexer. I'm wondering what the limits are on the device. I would like to see if it would do 449.9 on one port and 433.5 on the other.
7 Apr 2010 I have a VHF Celwave 636 series VHF duplexer. I haven't tuned a duplexer since 1994, so I'm a little rusty. Anyway, I put my IFR1200 on "tracking med", and tuned it to the lowest notch at the opposite frequencies. When I get done, I have a few issues/questions: 1. The TX radio now has a sensitivity of 2KuV.
