I was checking out the 19m band via the Twente WebSDR the other night when it was propagating well in Europe, and to my surprise I found a broadcast of China Radio International's Indonesian Service, STILL using the old interval signal from the Radio Peking era broadcasts.
They used "The East is Red" IS and the standard Interval Signal for CRI, the old IS hasn't been in use for at least 20 years at this point.
Very interesting to still see it broadcast, intentionally or otherwise.
Of course, it wouldn't be a proper post like this without a recording of what I heard, so the Soundcloud link is provided below.
All the best,
