Amateur radiogram service doesn't compete with other communications services, because there is no fee or guaranteed delivery. Provided FCC and international regulations are complied with, messages may be accepted from anyone for sending by Amateur Radio. Unimportant personal, non-business messages may be exchanged between different countries after a special agreement has been reached between the countries. A list of countries with agreements with the US appears frequently in QST and Amateur Radio electronic mail services. In addition, most countries don't object to actual emergency radiograms being handled if government or commercial facilities are not available at the time.
Amateurs handle radiograms in a number of different ways.
Some handle messages on individual schedules without using nets. Most participate in nets of various kinds. The largest organized system of nets is the ARRL National Traffic System. Any amateur can originate a radiogram on behalf of other individuals, whether the individual is a licensed amateur or not. It is the responsibility of the originating amateur to see that the message is in proper form before its first transmission, because under most circumstances it is improper for a relaying or delivering station to make changes.
