IARU Region 3 Conference

IARU-R3 LogoThe ARRL reports on the 16th International Amateur Radio Union (IARU) Region 3 triennial conference held in Bali, Indonesia, October 12-16.

Working Group 2 (WG2) dealt with such operational and technical matters as emergency communication, digital modes, a common APRS frequency, and Region 3 band plans. Titon Dutono, YB3PET, chaired WG2, and ARRL CEO David Sumner, K1ZZ, served as its secretary. In all, working group members discussed 37 papers and submitted recommendations to the conference for adoption.

Among recommendations adopted was one to ask the IARU Administrative Council to make available information on the use of the Amateur Satellite Service for member societies, satellite groups, Amateur Satellite operators, and concerned radio amateurs. This information would include, but not be limited to, criteria for a satellite to be in the Amateur Satellite Service and the procedure for IARU satellite frequency coordination.

The conference also adopted adjustments to the Region 3 band plans. Region 3 directors will consider making the format similar to that used in Regions 1 and 2.

The Chinese Radio Sports Association / Chinese Radio Amateur Club submitted a paper titled Amateur Satellite Guide which said “Amateur satellite projects may rely on a wide range of cooperation between radio amateurs and other parties, as the consequence, the nature of the mission can be complicated. Without a set of definite criterion, the service classification of a mission may not be crystal clear to both satellite operators and other radio amateurs, especially when the radio payload supplies amateur service but also covers certain kind of other tasks.”

The CRSA/CRAC proposed “that the IARU AC shall consider to make available some information on use of the amateur satellite service for member societies, satellite groups, amateur satellite operators as well as concerned radio amateurs.”
