Short Description I see what looks like some sort of AFSKAudio Frequency-Shift Keying all over 454MHz (looks like several channels of it). Most of the time it's the short bursts as can be seen in the waterfall, but occasionally it breaks out into a much longer ramble. It also sounds as though the carrier drifts up and down a bit during these longer bursts. In AMAmplitude Modulation or FMFrequency Modulation, it just sounds like someone keying a mic every second, but on sideband it sounds much more interesting, like the attached file. Cheers
