SB QST @ ARL $ARLB011 ARLB011 DXing on 60 meters has a downside, ARRL advises ZCZC AG11 QST de W1AW ARRL Bulletin 11 ARLB011 From ARRL Headquarters Newington CT April 5, 2007 To all radio amateurs SB QST ARL ARLB011 ARLB011 DXing on 60 meters has a downside, ARRL advises The ARRL is expressing concern that negative consequences could result from chasing DX on 60 meters. Some DXpeditions have announced plans to operate on Amateur Radio's only channelized band, where amateur operations hold secondary status to fixed service operations, including some US government stations. ARRL CEO David Sumner, K1ZZ, says that while it's legal for DXpeditions to operate on the 5-MHz band provided the licensing administration extends privileges there, DX pileups on 60 meters pose the potential for real and unique problems. ''US amateurs are limited to five channels on 60 meters, USB only, maximum effective radiated power (ERP) of 50 W, audio bandwidth not exceeding 2.8 kHz, and not all of the channels are useable because of ongoing fixed service operation,'' Sumner points out. Upon request of a primary service user, Sumner says, it's ''absolutely imperative'' that hams be prepared to relinquish any 60-meter channel immediately. This means constantly monitoring the transmitting channel. Hams also must not exceed the radiated power limit, he stressed. Not all countries authorize amateur operation on 60 meters. Transmitting on a 5 MHz frequency without authorization not only breaks the law but jeopardizes the operator's continued participation in the ARRL DXCC program. Five MHz cards submitted for DXCC may not be accepted for credit without evidence the operation was authorized. Sumner emphasized that causing harmful interference to fixed and mobile service stations could jeopardize even the existing, limited privileges as well as the chances of increasing those privileges on a domestic basis, plus any possibility of obtaining an international allocation on 60 meters.
