During ENOX19 on the quite strong MN/SD/ND -opening I checked also 1520 kHz. I noticed ESPN programming going on and I thought it's KOLM Rochester with its ESPN coverage. The signal faded in and out but just on the top of the hour the signal got stronger and stronger and I picked up KMSR Mayville legal ID. It was a pleasant surprise indeed! Actually I heard this one already back in 2005 as KMAV but since I did not hear a complete ID back then I could not get the QSL either.
This time the station manager quicky verified my report with a short email.
