The new repeaters are exactly the same at the older ones, and the older ones are capable of being converted to narrowband with programming, all Motorola and the all are in simulcast mode, we have plotted the differences between one that is wide band and one that is narrowband in over 50 different locations and the signals are, when seen by a mobile unit, weaker from the narrowband radios, the mobiles are all capable of both wide and narrow band service and of the 160 channels in the radios some are narrow band, also at the same time we added 3 new simplex channels on 150 and same result, car to car range is diminished somewhat however we have not measured that at the moment

Were the new repeaters the same model as the old? Were the new repeaters set up as simulcast as well?

We are in the process of adding 2 new sites to make up the difference. I am glad that you did not have a problem but this is just one of several which I have had a problem with, and I have become a believer in lost coverage, I have yet to see a system that has not lost coverage, I am glad that you have.
