[2] Its programming is also simulcasted on FM Translator W288BT, licensed to St. Clair, Michigan at 105.5 MHz, with an effective radiated power of 49 watts.

Between 2000 and 2019, WHLS simulcasted its programming on sister station WHLX in Marine City, Michigan.

Emrick would go on to broadcast Olympic hockey games and Stanley Cup playoffs for NBC Sports, and is a frequent guest contributor to sister station WPHM.

Liggett had also acquired Wismer's crosstown competitor, WPHM and WBTI that same year from Hanson Communications.

WHLS changed their format to active rock on April 20, 2015, with the first song being Smells Like Teen Spirit by Nirvana.

The new station is branded as "Rock 105.5", the frequency of the new FM translator WHLS acquired from a religious broadcaster the previous year.

The transmitter is located on 32nd Street in Port Huron Township, using the same site and same tower as sister station WSAQ.

[11] The FM translator originally started broadcasting on and off beginning in the summer of 2014 from the Radio First studios in Downtown Port Huron with 250 watts.

The station currently broadcasts with only 49 watts but from a much higher tower and covers the immediate Port Huron, Fort Gratiot, and Marysville areas.

One reasoning of Liggett Communications getting the 105.5 FM translator, is due to both WHLS and WHLX having limited nighttime range.
