Very good reception, some noise
From a skeezix post: Beginning November 15, 2021, WWV and WWVH will be broadcasting a test signal on minute 8 of each hour on WWV, and minute 48 on WWVH. This signal has been created to assist in ionospheric research, and is a joint effort of the Ham Radio Citizen Science Investigation (HamSCI) and NIST. The signal consists of various tones, chirps, and Gaussian noise bursts. The signal may be modified occasionally. For more information on HamSCI and the WWV/WWVH project, click here (https://www.nist.gov/pml/time-and-frequency-division/time-services/wwvwwvh-scientific-modulation-working-group)
