15:32z FSK (RTTY?) stopped broadcasting on 4724 kHz.
Specifically, centered on 4726 kHz; shift seems to be 850, Baud is ?. Was already present when I tuned in, would have no clue last time I checked 4724 kHz so could have already been going on for quite a while.
Broadcast without any apparent break until 1532z. Almost certainly coming from California as for the entire period of time, some SDRs further away from California have gotten good reception at various points of day, but only those in California have consistently got enjoyed reception for the entire duration.
