Jack, Contact Sinclair Tech Support for guidance. Go here:
<www.sinctech.com> Some Res-Lok duplexers are problematic when attempting to move them to a new split, because the coupling between cavities is via a machined slot rather than an external jumper. Dunno if yours is like that. When you call Sinclair, have the duplexer model and serial numbers handy, along with the operating frequencies marked on the label. It may be possible to have your duplexer modified at the Sinclair plant. Although this is expensive, it's a heckuva lot cheaper than buying a new duplexer. The main benefit, of course, is that perfect performance on your repeater pair is guaranteed. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jack Davis Sent: Sunday, December 23, 2007 7:47 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Duplexer help I have a Sinclair ResLock 900 MHz duplexer that I am trying to retune to 902-927 MHz. It was on 941.XX with a 3.6 MHz split and the pass cavities tune up just fine but the notches do not make it to the 25 MHz split. Has anyone made one of these work in the 25 MHz split used in the Ham band? I could sure use some help with this one! Jack K6YC
