The continuing mystery behind the move of SAM and the static on 107.3 may have been solved by GreaterFalls friend James C, who writes:
As of Monday 107.3 has made it’s move to 102.7. I will miss listening to them in my town and being able to hear them all the way when I drive to Great Falls.
I just got a reply from the station. Turns out it was a station sale deal by the owners that involved purchasing 101.7, 102.7 and 103.9. They sold 107.3 as part of the deal. 107.3 will be country music station soon.
Which reminds me – the “new” SAM at 102.7 sure does seem to have lots more local voice this week.
