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!
