Primary Evanston Police operations are on the STARCOM21 800 MHz P25 trunked system; channels here are conventional analog. The lifeguards repeater (WRWI447, 152.330/157.590) has an unusual +5.26 MHz split landing in the VHF Marine band — sourced as-is, flagged for verification. 155.760 is shared by Public Works (KDN985, 123.0 PL) and Electric (KDM250, 77.0 PL) with different tones.
