[Motorola] MICOR repeater UHF

[Glenn Little]

We finally got our MICOR UHF repeater going somewhat correctly.  Turns out 
we had low drive to the tripler from the exciter.  Original problem was low 
power out which we thought was normal for the radio being used out of 
band.  The day after the repeater was placed on site the power out dropped 
to zero.  After a few false starts, the problem was localized to the filter 
between the exciter and the tripler.  After retuning this filter, the power 
went right back to where it was in commercial service.  Still think that we 
have a problem with loss in the circulator, but that appears to be acceptable.

We now cannot get rid of the squelch taiol on the repeater.  The repeater 
was originall a DPL encode and decode unit. We are using it as carrier 
squelch.  We moved the obvious jumper to convert the unit from DPL to 
carrier squelch.  Does anyone have a list of what has to be changed to get 
rid of the squelch tail?  Any help greatly appreciated.  This repeater is 
used to link a number of repeaters together and the squelch tail is 
anoying. We do not really want to use PL as the decode time chops the first 
word.

Thanks
