Eureka Springs PD, unlicensed transmissions?

I'm helping a friend listen to Eureka Springs PD. She contacted the PD directly, they told her that they switched to icom radios and NXDN. So far using SDR, ive seen transmissions on a few freqs, but they dont show in the DB at all. I find this strange because they're supposed to be registered with the FCC.
