      NSEA .700 system extending coverage across the greater Chicago metro.
      Original site was the former Dyche (Ryan) Stadium on Central St in
      Evanston; with the stadium demolished for the rebuild, the repeater and
      antenna are temporarily on a nearby cell tower at lower height, so
      current range is reduced. Permission required; 107.2 Hz PL (NSEA does
      not publish tones publicly). Coverage approx 15 mi. Output 462.7000
      (+5.000 input).

      Evanston .725 - cooperating system privately owned by Matt (NSEA Unit
      595); NSEA members are invited to use it. Contact the system owner for
      access; 100.0 Hz PL. Antenna is directional facing north, so HTs and
      mobiles south of Golf Road will struggle to access it. Coverage approx
      20 mi. Output 462.7250 (+5.000 input).
