The normal priority is Emergency, Priority, Routine and Health and Welfare traffic, in that order. Some nets will not take Health and Welfare traffic, preferring to send amateurs with such traffic to other nets specifically set up for that traffic. ALL nets should take priority and emergency traffic if there is not a better net available to handle such traffic. Regular participation in emergency nets is the best way of staying current and understanding the operations of a particular network. In addition, it makes sure your equipment is operating properly and helps you to understand your station's propagation coverage in a particular net.
All nets have particular procedures for checking into the net.
Relays SSB nets and FM Simplex nets will require relays if there are weak stations trying to check in with traffic. Many nets have established policies in dealing with relays, sometimes alternating NCS to widen the net's reception due to propagation. Regularly scheduled nets Nets held on FM Simplex frequencies are usually called into effect as backups when normal FM repeater communications are disrupted or to handle local traffic. These nets hold special challenges for all concerned, and are closer to SSB nets in function than they are to FM Repeater nets. For that reason, experience in operating on HF SSB nets will hold the operator in good stead during a simplex net.
