This from Jim Linton, VK3PC, Chairman of the IARU Region 3 Disaster Communications Committee, via the Southgate Amateur Radio Club website:
At the request of Central Emergency Communication Committee, Ken Yamamoto, JA1CJP, the IARU Regional 3 Secretary, said the JARL is operating its HQ station JA1RL in Tokyo, and regional HQ stations.
Earlier it was reported that JA1RL was using 7 MHz SSB, 144 MHz SSB/FM and 430 MHz SSB/FM.
“Many other radio amateurs are thanked for providing information and exchanging support to the rescue and disaster relief operations," JA1CJP said. "Those who can operate in the affected areas are providing a lifeline for rescue teams and those at local shelters. Some stations are operating with car batteries and others with engine generators.”
