An internal Part 15 radio station featuring the Packers Radio Network play-by-play, along with public address and scoreboard announcements, serves the area surrounding Lambeau Field during Packers home games to provide the game call to those in attendance without the delay experienced by Journal Communications uploading the network feed via satellite. The feed is on a non-standard FM frequency which requires purchase of a special radio tuner to listen to that signal clearly, though it is audible with cross-channel interference from Wisconsin Public Radio's WPNE at 87.5 FM on regular tuners.
The Green Bay stations designated below in the table are considered additional "primary" stations in the network. This designation only truly comes to use in the later stages of the NFL Playoffs if the Packers make it to the NFC Championship Game and the Super Bowl, where those primary stations can carry the Packers Radio Network local call. All other network stations, including those in the Fox Cities, must carry the national Westwood One call instead in line with NFL rules.
Its primary programming consists of broadcasts of Packer home and away games to a network of 56 stations in Wisconsin, the U.P., Iowa, Minnesota, North Dakota, and South Dakota, along with a two-hour pre-game show and three-hour postgame show which allows listeners to call, email, or text in a sports talk format about the finished game. Wayne Larrivee has been the play-by-play announcer since 1999, while former Packer center and current WGBA-TVsports directorLarry McCarren has worked as the color commentator since 1995. Both Larrivee and McCarren contribute to the team's television programs, in addition and work with WTMJ's television sister station WTMJ-TV in Milwaukee (WGBA is also owned by Journal Communications).
Though its broadcasts began in 1929, WTMJ did not begin paying the Packers for broadcast rights until 1943; it paid the team $7500 to broadcast the season. In the early 1930s, there was no exclusive right given to broadcast games, and WHBY, then based in Green Bay, often sent its own announcers to call the game. From 1933 to 1936, three additional stations carried WTMJ's radio broadcasts of Packer games: WLBL in Stevens Point, WTAQ in Green Bay and WKBH in La Crosse. WSAW in Wausau and WJMS in Ironwood, Michigan started carrying the feed in 1937.
