ii. Establish and deliver the curriculum
iii. Test the knowledge

d. Practice (commit)

i. Use licensed radio services – an existing community
ii. Join local radio clubs – infrastructure, assistance

iii. Build additional facilities
iv. Attend regularly scheduled “nets”
v. Conduct simulated emergency tests

2. Match technology to group objectives (and vs)

a. Effectiveness of technologies
