Phelps-Dodge duplexer You must know that Phelps-Dodge has been gone for some decades now. Common sense would say your six cavity unit was made for wideband commercial repeater splits (about 5 meg). Your picture didn't come through to the yahoo group. The capacitor/box assembly is probably a method to add reactance to the probe/loop. You can see what it really does on a tracking spectrum analyzer. Harness lenghts are common values, depending on your probe/loop interface. You might review some of the seits web site information to get a better handle on things. Depending on the Cavity Q and probes, you might be able to use it for some Amateur applications. cheers skipp www.radiowrench.com > ----- Original Message ----- > From: kerry > Sent: Tuesday, May 25, 2004 4:54 PM > Subject: Phelps-Dodge duplexer help > A friend has acquired a phelps-dodge 6 cavity duplexer catalog number 499-509, serial number 1374. It is configured in a circle and each can has a box with a tuning capacitor mounted on top of it. It says it covers 136 to 174 MHz. It has no connecting cables and no instructions on cable length or tuning. Could someone help with this information. I have searched the net to find any information on this duplexer with no results. I have attached a picture............thanks > Kerry-WA2NAN Yahoo! Groups Links Yahoo!
