This week WNUA's call letters were changed as the station now is Big Country 95.5. The station was originally WDHF which became WMET to becoming WNUA where for decades it began playing New Age to be expanded to Smooth Jazz. A few years ago the format was changed to Mexican music but the call letters stayed intact. Last week, a surprise flip to country took place and this week the WNUA call letters were changed. So we say farewell to WNUA.
