This is one tuning task for which my Simpson 269 VOM is worth its weight in gold. A sensitive analog meter with a huge scale is invaluable in detecting those tiny peaks and dips.

Hi Jason, The real key to realigning the MSR-2000 Receiver and Transmitter strips is to follow the first pre-alignment task item listed in the Service Manual. Back all the inductor (coil) cores out of their forms to the locations indicated in the chart/position table/pictures. You must do this when moving the units more than 1MHz from their last known aligned position. Then start your new alignment from scratch. From memory I will tell you one of the meter dip/peak indications is very, very small and easy to pass over to the next wrong position so pay very special attention to the actual meter movement as you go through the steps. Hope that helps... cheers, s. > "kc7stw" <kc7...@...> wrote: > > Hello all. > > I have a UHF msr2000 exciter that does not want to play nice. > > It was working on its original frequency of 461.100 and > drove the PA at 100 watts. > > I am trying to move it to 440.300 I have followed the steps > in the Moto manual for peak and dip. peak and dip. done > this about 6 times. > > The exciter only wants to put out about .1 mw of power. > > What am I missing?
