Re: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF
Hi have you measured the DC volts on load. It maybe the regulator in the psu has gone. As our friend says look at the DC output with a scope and see if it is clean and not have loads of AC . 73 Steve M1SWB - Original Message - From: David VanHorn [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Thursday, July 28, 2005 8:01 PM Subject: RE: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of ANTHONY Sent: Thursday, July 28, 2005 1:58 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF I AM BACK AGAIN, WITH THE SQUEALING REAPEATER PROBLEM.JUST BY CHANCE , I HAPPEN TO NOTICE THE AMP METER ON THE POWER SUPPLY WAS DECREASING IN AMPS FROM WHAT IT WAS PULLING, IT WAS DROPPING BACK TO 5--AMPS OR LESS, AND WHAT IS HAPPENING IT IS DROPPING BACK IN OUTPUT POWER WHEN IT IS SQUEALING,WE HAVE IT SET FOR 50--WATTS, AND NOW IT HAD DROPPED BACK TO 40-WATTS, BUT NO SWR ON THE ANTENNA.AND PUT A DUMMY LOAD ON THE TRANSMIT SIDE OF MICOR, AND IT IS STILL DOING IT.ANY IDEAS ON THIS PROBLEM AND HOW TO SOLVE IT?

RE: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF
we have a backup REAPEATER spectrum and it is put out 75 W VHF no problems same power supply? and no SQUEALING REAPEATER anymore ID,s thanks for previous replies ANTHONY W4NCR I'd still check the supply. One bunch of hardware may be more tolerant of that type of problem than another.. Yahoo!

Yet never keys up on it owen ? ---Yep, sounds exactly like a mix that involves your own repeater's transmitter. Obviously, there's something else out there that, on an occasional basis, that is figuring into the equation. Now the hard part You need to do the math, based on your xmt and rcv freqs and a 3rd (or maybe even 4th and 5th) source of mixing freqs, that result in products on your receive frequency.

RE: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF
Anthony, Does sound like intermod. Micor has tight front end, but if problem is with intermod the undesired signal could end up near or on your freq. Would be nice to be able to disconnect antenna when the problem occurs to see if from external or internal to Micor. Wonder if you are using preamp before the Micor??? 73, ron, n9ee/r Ron Wright [EMAIL PROTECTED] Ron is the owner of Micro Computer Concepts, a manufacture of repeaters and repeater controllers since 1988.

Hmmm,sounds like a band opening to a reverse split repeater. Could be conditions! Happened to me before...search the repeater directory!

Re: [Repeater-Builder] Re: MOTOROLA MICOR receiver VHF
Anthony If you haven't changed anything since it worked right---tighten all co-ax connectors before you do anything else---a loose connector in either the transmitter or receiver lines to the duplexer can be the cause of problems just as you describe. Good luck.

Get a receiver and go off of your input channel either up or down by 10.7, 10.8 or 11.7MHz and tell me what you hear.
