I recently purchased a PRO-96 and am having a devil of a time understanding trunking and Talkgroup programming. I live in Scottsdale, AZ and want to program Scottsdale PD and FD as well as Phoenix frequencies. I just purchased a Southwest Frequency Directory, but I am having difficulty programming in Scottsdale as it only gives TG: 4208 for example. Can anyone provide me with a simple step by step process for programming or direct me to a resource? I am using Win96 Software, but I don't seem to be making progress on trunking and talkgroups. The book that came with the unit is worthless. Thanks in advance for your assistance.
