WPNA-FM (103.1 MHz) is a commercial FM radio station licensed to Niles, Illinois, and serving the Chicago metropolitan area.

[4] The construction permit for the 103.1 FM frequency was issued to North Suburban Radio on November 23, 1960, bearing the WHPK call sign (soon changed to WNSH-FM).

[9] Among the air personalities during this time were Ed Walker, Dale Scott, Lori Rhinegold, Paul Knutson, and Mike Megaris.

[1] By 1977, the station had adopted a brokered ethnic format, airing a high amount of German language programming.

[2][28][23] In 1999, the station's transmitter was moved to its current location in Arlington Heights, Illinois, and its ERP was increased to 6,000 watts at a HAAT of 100 meters (330 ft).

[35] The station featured longtime Chicago area radio personalities including Robert Murphy, Fred Winston, and Mark Zander.

[36][37] On January 29, 2001, after playing "Never Say Goodbye" by Bon Jovi, WXXY/WYXX adopted a Spanish hits format, branded as "Viva 103.1".

[46][47][48] Shortly thereafter, Hispanic Broadcasting Corporation purchased adult-contemporary station WJTW 93.5 ("Star 93.5") in Joliet and it began simulcasting WVIV-FM, with its call sign being changed to WVIX.

[60][61] A condition of the sale was 93.5 WVIX completing its move to the Oakbrook Terrace Tower, where it would operate with an ERP of 3.5 kW at an HAAT of 133 meters.

[2] The acquisition by The Polish National Alliance was consummated on August 31, and the station changed its call sign from WVIX to WPNA-FM.
