E10 blooper

E10 is one of the most common numbers stations in the HF spectrum. Despite the large number of transmissions, usually they make no mistakes. Well, most of the time. Today, while listening on 3150 kHz at 1900z (a "hot" PCD slot) suddenly the operator switched for some seconds from "PCD2" to "ULX2". Here is a recording of the event. And these days, they start late, about 1 minute late! Maybe is the "New Year's Eve hangover effect"!
