Hi Gordon, Most in my area like the duplexers made by TX RX Systems Inc. www.txrx.com<WebLink/WebLink.aspx?LogEventType=WebLink&key=eqqm%3a%2f%2fttt.quou.zlj&corporateKey=900254929%5CRBI.Kellysearch.PresentationControls.common.HBXUrlName> I have several sets VHF and UHF in commercial and Amateur use. I have one set that has been on my VHF Repeater for almost 20 years and has never been touched and are still on spec. Customer Service is available by calling and asking for Mary Brown. She came up through the ranks in the factory and can tune a duplexer as good as anyone and is now taking questions and wants from the customers.
Good luck.....JIM KA2AJH On Thu, May 6, 2010 at 10:51 PM, Gordon Cooper <[email protected]> wrote: > > > Was looking for something else in an old ARRL Handies & found the > comment that "the 567 requires high quality capacitors to maintain > stability". > > On another subject, any advice on purchasing duplexers for 2 metres? > Our local supplier has closed down and such items are like hens teeth > here Down Under. > > Cheers, > Gordon ZL1KL > Tauranga > New Zealand. > > -- Jim Cicirello 181 Stevens Street Wellsville, N.Y. 14895 (585)593-4655
