Threshold carrier here fading in and out of the noise floor since 1258 UTC. No detectable audio yet....interesting posting!

Yes skip, that is exactly the loop, unmodified, direct link here
http://archive.lib.msu.edu/VVL/vincent/presidents/mp3/coolidge.mp3This station is repeating that loop over and over. Locally here it is very weak, however remotes made it possible for me to hear it well.
This is probably not a pirate, but what it is is unsure. These kinds of stations show up periodically. Interestingly, I have logged one of these kinds of stations in March of the last two years.
Here is one from last year, March 16, 2017. It was a 5 minute loop.

(edit) Looking through my log and recordings I find similar transmissions on 9225 kHz in Aug of 2013, 17795 kHz in March of 2014, 14965 kHz in March of 2016, 4947 kHz in March of 2017, and then today, 9025 kHz in March of 2018.
(edit 2) This station was still on air at 1930z, but when I checked last, at 2045z, the station was off air.
T!
