Well... First: If you have the original cable set and know the frequency of design... might be prudent to replace them into service to see if you can obtain the spec'd notch value.

Then have a second look... cheers, s. > Joel Hall <[EMAIL PROTECTED]> wrote: > > Hope some of you guys that have some experince with db 4060 duplexer,the pass is fine but the notch is the problem I can see the notch at around 35db on my ifr 1600s per each can but when i combine them together about 50db is the best i can get I have new cables made 1/4 wave long , the tuning caps seem a little flakey may have had been hit with a lightning surge. > I have not taken them apart yet so any thoughts? > > Thanks kj4si >
