I scan a P25 frequency with frequent traffic. On the DSD+ P25 1R Channel Activity screen it shows Target and Source numbers for the traffic. I also have a well populated DSDPlus.radios file that contains some 90,000 entries. I obtained the file from some download that was offered in one of these postings. What am I missing? I would like to see what agency the traffic is from instead of a source number. Decoding is fine otherwise.
