Put your crystal into another element. I had the same problem and the second element allowed me to center it right on Freq.
Good Luck JIM KA2AJH _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, January 27, 2007 12:29 AM To: [email protected] Subject: Re: [Repeater-Builder] UHF Micor Off Frequency This is why year after year, on this list, the word is continually put out: Send the elements in to have the crystal manufacturer install the crystals, temperature compensate, and net them to frequency. They know what to do. Correctly. Don't waste an otherwise excellent performing MICOR radio by messing up the one piece you have control of - the crystals. You don't save money in the long run by being cheap on the crystals and crystal manufacturer's services. Do it right the first time and be done with it - for good.
