Hi all. One of my friends is getting a 2 meter repeater ready to put on the air. He asked for my advice regarding a duplexer for sale on e-bay. It is a Sinclair Q2330E. I looked at the pictures and it is in immaculate condition. The picture shows this duplexer to be on 168.750 and 169.875 MHz. I noticed one thing however. The tuning rods were sticking out only about 1.5 inch from the tightening nuts. I have tuned many of this type of duplexer in my work environment.
To go from 169 down to 146 MHz the rods have to be pushed in by about 3 inches. No mention was made on e-bay that it had been tuned or used on 2 meters. In fact if it has not than this duplexer will not go down to 146 MHz because the rods are too short. Luckily he didn't put an offer on it as the seller did not reply to his questions on it. I am NOT saying that this information was withheld on purpose but it proofs the point of "buyers beware". I also suggested to him to contact Sinclair re the possibility of having to replace the harness. Here is Sinclair's response verbatim. (note the unsolicited second comment) *************************************************************** Subject: RE: Form Submission for Technical Assistance There is no need to change harness, but make sure the tuning rods are not cut or they will not be able to tune down to your freq, sometimes they were cut to fit into certain rack space.
