Sections of PART97 Relevant to Multicast Protocol Operation

Following are sections of PART97 that specifically affect multicast protocol operation. All of PART97's regulations of course apply, but these are of particular interest to operators utilizing amateur multicast protocol. (AMP)



97.3 - definitions:

(26) Information bulletin. A message directed only to amateur operators consisting solely of subject matter of direct interest to the amateur service.

(32) Message forwarding system. A group of amateur stations participating in a voluntary, cooperative, interactive arrangement where communications are sent from the control operator of an originating station to the control operator of one or more destination stations by one or more forwarding stations.

97.111   Authorized transmissions

(b) In addition to one-way transmissions specifically authorized elsewhere in this part, an amateur station may transmit the following types of one-way communications:

(6) Transmissions necessary to disseminate information bulletins.

97.117   International communications.

(c) Except as noted in (d) of this section, for stations participating in a message forwarding system, the control operators of forwarding stations that retransmit inadvertently communications that violate the rules in this part are not accountable for the violative communications. They are, however, responsible for discontinuing such communications once they become aware of their presence.
