I find it easier to enter in my frequencies in order with the Icom pcr program then name it for the location or system you are trying to listening to. Then set up a trunk bank in trunkpcr, then export the Icom mch file from the icom program file.The only thing you need is to edit the channels which usually means to get rid of the first channel since it is a default frequency.If you have problems then email me direct then give me the link to the frequency data base I will be glad to set up a trunk bank for you.
Trunkpcr I found is the best program (for the money) that not only gives you good function but provides you with information for the system.Its only a click away. Jay (crazycalfornian) wrote a excellent program. I use it for everything.
