Amateur radio operators must be licensed by the government. In the United States, the Federal Communications Commission issues amateur radio licenses. Normally, a test on operating practices, radio theory, and in some cases a Morse code proficiency test is administered. Amateur radio is not used for commercial purposes. Also, amateur radio operators are restricted from using profanity and using amateur radio for illegal purposes.
Packet radio is digital communications via amateur radio.
Packet radio is so named because it sends the data in small bursts, or packets. The City of Eureka maintains a 2-meter radio and packet radio system on 145.090.
