At 0938 I was getting accented English and a time check for 4:38 AM.
Then into a reggae version of Simon and Garfunkle's 'Bridge over
Troubled Water'. I think this may have been the Jamaican station.

I heard that too !

Did it sound like this:

Listening in AM mode was pretty useless with a spanish station 100hz high.
Still need to go over notes and tapes.
