I have a pro-163 and can't get this http://www.radioreference.com/apps/db/?sid=712 trunking system to work. It works fine on my pr0-2055 but will not pick anything up on my pro-163. The base and offset are set the same on both models but for some reason the pro-163 will not receive anything. it seems that everything is set the same between the two but it still will not pick up the trunked system. Please if anyone has any ideas let me know. Thank You
