I don't mean to sound dumb, but are you saying the VHF spec'd cans will work on UHF as well, I do have a couple of nits to pick with TX/RX about these cans however. 1) BNC connectors?!?!?! 2) It is next to impossible to get in there and tune the notches on 3 of the cans because of the location of the adjustment caps. 3) Lack of a fine tuning for the pass rods. They slide in or out. No fine threaded adjustment for when you get them "close".
Other than that, they seem great! I was going to turn them around and sell them, but I may part with a set of Q-202g's instead. 73 Norm ----- Original Message ----- From: Repeater-Builder@yahoogroups.com <Repeater-Builder@yahoogroups.com> To: Repeater-Builder@yahoogroups.com <Repeater-Builder@yahoogroups.com> Sent: Sat Sep 26 23:20:17 2009 Subject: RE: [Repeater-Builder] TX/RX systems duplexers. WOW!!! Hi Norm, I have two sets here, one new out of the box and a older unit but the same series of duplexer. I tuned them to tx447.125 & rx442.125 and experienced the same as you have found. I am using a HP8920 and my other unit is a HP8924. Both show the same so I would say your units are working.

WOW!!! I wound up with a set of Tx/RX 28-38-03-C vari-notch duplex today. I was not expecting much. I got them cheap. The cans are only 4". No big deal. Bigger cans = deeper notches with less insertion loss, right? Well, unless my site master and IFR-2945B are lying to me, I got -100db on the notches and 1.2 db insertion loss! I will say this, the coupling loops are very different than what I have seen in sinclair, telewave and db cans. Does anyone else have any experience with this model? Am I reading things right?
