Bellwood appears to be the only 154.8225 licensee in Cook County. WPWS454 covers a repeater on that frequency with an input of 159.4125. Just heard a Bellwood PD (300-series) unit there with a traffic stop "on 3". As in the past, DPL351 was used. If you were using a Radio Shack scanner to search for the tone, some models are known to provide a false reading of 136.5 PL if in fact DPL is being used.
Have Hillside, Maywood or any other PDs been heard using this repeater?
