SW BC interval signals

I know this has been posted before, but it is quite good to hear some of these again. If you are like me, your first introduction to amateur radio was via shortwave broadcast signals. Shortwave is quite different these days with far fewer English language broadcasts. It is no longer the magic it was to oldies like me!
