In order to reduce congestion on VHF working channels, Marine Rescue NSW have allocated different working channels for adjacent radio bases. Marine Rescue Lake Macquarie’s radio base at Swansea Heads is now using VHF Channel 19 as its main working channel. Some VHF sets can be switched between International and USA. Vessel owners need to ensure their radio is set to “International” , not “USA”, in order to satisfactorily converse with our radio base on Ch 19. A setup guide is shown below.
