[Repeater-Builder] Can a Master 3 narroband

[Jim in Waco WB5OXQ]

I have a uhf master 4 that has been used for years as a paging exciter.  Now 
the pager business is in the tank I would like to make the master 3 into aq 
repeater for commercial needs to replace a msr2000 because the msr cannot 
narroband.  If the ge can't either I dont want to waste time and just buy a new 
repeater that can narroband.
