Normal usage of the frequency is stopped. Net Control Stations can quickly become overwhelmed by rapidly accumulating administrative and logistical requirements. This reduces the traffic flow to, and maintains the efficiency of, the main net. They report and respond to the main net. All communications must pass through the authority of the NCS for the duration of the net.
Personal transmissions are inappropriate.
If this occurs, you will know that the NCS is in a Tactical or Command Operations mode and is very busy. Go to the requested frequency and check-in with the NCS there. Stay on the Resource net frequency. A Resource Net is a holding area where you will stay until given an assignment. When you receive your assignment from the Resource NCS, follow his instructions exactly.
