      Skokie conventional public safety, public works and park district channels. Primary
      police and fire dispatch have moved to STARCOM21 (P25 Phase II); Skokie Police
      dispatch (TG 3684) is encrypted. Skokie also dispatches Lincolnwood Police/Fire.

      Police and fire units have access to talkgroups in the 36486-36500 range, with both
      clear and encrypted use observed. The 154.340 Fire Admin channel carries a patch to
      STARCOM21 TG 36500, which makes it the most useful conventional RX channel for
      following Skokie Fire activity.

      Park District (KJU960, 151.310) and Public Works (KCR894, 154.100) are municipal
      Part 90 local-government channels, filed under public_safety_part90 to match the
      convention used in the Evanston file.

      RX-only for the general public per Part 90.
