I just got a RS Pro-94 but when I follow the instructions for entering
trunking frequencies it doesn't scan for the data channel.

Is it possible that you don't have all the freq's in it? One time I had a
scanner programmed and up and running and it suddenly quit trunking. Come
to find out that the city had added more freq's to the system and moved the
data channel to one of the newly added frequencies. Thought I was going nuts
before I figured it out. Tulsa used to have 20 freqs but now has 30.
