Mike,
The way a micor base repeater is set up from the factory is
to use de-emphasis and pre-emphasis through the machine. The discriminator
is de-emph'd, run through the control circuitry and then pre-emph'd in the true
FM exciter. (hence the lengthy discussion)
Anyway, looking at your
Mike how did you do the link? did you
make the micor 1/2 6 meter the other 440? or did you set up a complete two site
ra/rp configuration like in the moto book?
When linking two micor base or repeaters I
use a line driver to the link xmiter. If for full duplex I use a 4 wire
line driv
Oh, don't do this - the coors brewery will have to work overtime during
the summer months when families want to vacation with the kids out of
school. I think someones eyes have swelled shut already, is the micor a
pm or fm on both ends?

Hi Kevin,
I could be wrong, but I believe all low band Micor exciters (including Stations) are PM. This is likely the case because it is difficult to modulate the crystal frequency via direct FM, retain good linearity, and achieve 5 kc's of final deviation due to the multiplication factor.

If I remember right, MOST low band micors are PM. However, you could ge the
later ones with DPL and those models had a different exciter that was true FM
with a different channel element than the PM models.

Maybe I'll have to convince the sales guys to give

I'd be vary suspicious of the pins and contacts on the exciter.

I am dealing with a similar problem with a Mastr II and a NHRC controller.
The audio sometimes fades out dropping to a very low level, and changes
while you are listening to it on a repeater user, although it comes back
all by itself. It seems to be an analog problem as opposed to just cutting
Try giving the deviation control a spritz of cleaner and then run it back
and forth several times.

Replace the deviation control pot on the exciter. I have replaced many on
those vintage radios when in mobile service.
You could hit it with tuner cleaner also. :)

So no one volunteers like that any more. They get
sucked in and then there's no way out.
