I have a Micor base that was manufactured in the ham band. Model is C64RXB3196A-SP71. The receiver model number is TRE1241A-SP10 (420-450 Mhz). It came with 4 channels all tuned up and on frequency in the ham band. But the receiver is sensitivity is .72 mv for 20 db quieting on the best channel and .9 on the worst. I went through the alignment procedure and could not make any improvement. Obviously this is not meeting the .5 spec and I was expecting more like .3 or so.
So my questions is what should I do to troubleshoot this? Is there some common Micor receiver failure parts or areas that I should be looking into? -- Tim :wq
