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?????
Have you tried a large capacitor, on the DC input?
Maybe 10,000uF or better, low impedance type. ("low esr")
If I was there, I'd hang a scope on your DC supply line, but I can't do that
remotely :)
