[Motorola] Funny-Acting Micor Question

[James Coote]

I will be helping someone with a repeater problem on a distant mountain top.

A carrier-squelched Micor repeater seems to boost or emphasize PL signals on
the repeater input.  A subscriber radio PL is set to the norm, but on the
output, the repeater is distorting the subscribers audio.  It happens on all
subscribers in this carrier-operated repeater, when they forget and have PL
enabled in their radios.

Do you think this is a matter of cleaning and reseating the boards and doing
an alignment- or are there equalization jumpers to deal with?
Or (the horror!) could it be an Amateur has "modified" something?

Thanks,
Jay
