1. A method of detecting signal interference among geographically co-located radios affiliated with different talkgroups, the method comprising:
receiving, at an electronic computing device, a log of push-to-talk (PTT) operations performed at a first radio while the first radio is affiliated with a first talkgroup, wherein the first radio operates on a first channel frequency assigned to the first talkgroup;
receiving, at the electronic computing device, a log of audio quality values measured corresponding to audio communications received at a second radio while the second radio is affiliated with a second talkgroup, wherein the second radio operates on a second channel frequency assigned to the second talkgroup;
determining, at the electronic computing device, that the audio quality values indicate a change in audio quality exceeding a predetermined audio quality threshold; and
detecting, at the electronic computing device, that signal interference at the second radio is potentially caused by the first radio when there is a time correlation between at least one of the PTT operations performed at the first radio and the change in audio quality at the second radio and further when the second radio was geographically co-located with the first radio during the time correlation.
