Hearing intermittent "digital, encrypted(?)" signals on Weber County Simulcast

[K5KNT]

I haven't been listening for a few weeks, but today I'm hearing intermittent signals on Weber County Simulcast that sound encrypted or digital. It also reminds me of HF radar signals from when I used to chase those. Nothing shows up from the RRDB when this occurs and I haven't noticed if it is on the same frequency.

I'm using Unitrunker 2.1.0.106 on a Windows 11 machine.

Is anyone else hearing this or have an idea of what it might be?

Looking through my recordings from Trunking Recorder, the sounds are coming from three unidentified group IDs: 5184, 6688, and 15328.

Update: The interference appears to be coming from Trunking Recorder, as the noise goes away when I stop recording.
