Vern,

Yep you got a Micor...a mobile repackaged as a base station.

Might look at the PA.  The more transistors the higher the power.  The PA came 
in 45/60/110 W.  However, in this configuration if using for repeater turn down 
to maybe 50% rated power out.  This is adjusted with a pot in the Power Control 
Module, just to the right of the PA.  Also add a fan.

However, before you get started find what band split it is on.  It is VHF (can 
tell by the 5 inline helicals in the receiver), but need to know segment.  As 
another posting there were 3, 136-150, 150-160 and 160-174.  The 160-174 is 
useless for Ham.  Some trouble moving 150-160 down to 146, mainly with 
receiver.  Exciter and PA will most often tune with maybe 10% reduction in 
power.

The power supply is 25 Amp continuous duty Mot used in their 100 W repeaters.  
Very good power supply for this.
