New Working Channel

(Tuesday 28 June 2021)

Following changes made by the International Telecommunications Union (ITU) Tas Maritime Radio (TMR) has changed its ship/shore VHF working channel to CH66 because the ITU decided to split duplex channel 78 into two simplex channels.

New radios coming onto the market now include the new channels, CH1078 and CG2078, as well as the original CH78. This is a recipe for utter confusion and has already caused problems for some mariners which is why we made the change.

Even CH66 has a potential for problems. Even newer radios have a CH66A which is a different channel that appears in US and Canadian modes. So, please ensure your radio is switched to the International mode otherwise you will be on CH66A and not CH66 and you will not be able to make contact with TMR.
