The Simplex Net divides Lancaster County into three zones based on major roads. The Northwestern zone (WEST) is North of US 30 and West of PA 501. The Northeastern zone (EAST) is North of US 30 and East of PA 501. The Southern zone (SOUTH) is anything South of US 30.
There will be one net control station designated from each zone during the Simplex Net. During the net, control operations will transfer from zone to zone as needed to obtain as many check-ins as possible with a minimum need for relays.
In addition to Zone controls you will hear Central control. Central control’s purpose is to start and end the net and keep the hand-offs between zones flowing smoothly.
