At Circular Quay today the Ovation Of The Seas arrived back in Sydney. I picked up some of their comms on 457.575MHz and 457.5625MHz DMR Simplex. Sounded like admin type chat.

Then I hear on 457.575MHz analogue with 210.7Hz subtone, "Freshwater, Freshwater" and some discussion about docking. I'd say the ferry master calling the wharf line handlers on approach? There's nothing listed on ACMA for that frequency being licensed to Sydney Ferries. It is an international UHF maritime allocation which is to be used by "Cruise ships" and "Ferries"

I found this website very handy https://radiofreeq.wordpress.com/2016/0 ... ogramming/

Yep, its a bit of a mess when its busy on the harbour - however they are using subtones and DCS. It can bee very bloody hard to work out some of those cruise ships sometimes you have to note them and try and reconfirm when they re-arrive and at times i assumed i had logged a particular cruise ship when infact i had something else.

I do recommend this page - https://scanmaritime.com/frequencies.htm - it has got me out of trouble a few times. But majority of the ones coming in these days are DMR. All of those ferries are analog with a subtone and if my memory serves me right, each one had their own subtone and is programmed into each ferry so they can be contacted outside of GRN.

Yes it was difficult determining who was who with all the different transmissions around the harbour. And I did note the subtone on the ferry transmissions, 210.7Hz.

I enjoy marine monitoring and look forward to my visits to the big smoke to scan the harbour
