It's not the slow dasher that was 4097.08 in 2020 but maybe it is McGreevy's "Madonna" beacon resurrected to run day and night? Orig. on 4097.23
This is a quicker dasher on 4097.24 Khz that I can hear decently well at home and it is pretty strong on the KFS SE kiwi, about S5 compared to the Desert Whooper's S9
