Did you try the different filter settings and IFX to the frequency shown when you hear the interference? You can get interfered from other frequencies if they are -80dBm or stronger. If your monitored system that gets interfere are -70dBm or stronger you can probably engage the attenuator to that system to get rid of the interference.My scanner does this but I see it on a few uhf freqs.
