Hi all, just had a thought. With buses going underground in the new few weeks, what radio communications will they use while under there? Bus's are often communicated with when on stand and I imagine it would be hard to get an existing signal under there. Will they have repeaters?

Don't know but they have some options. They could use a leaky feeder to repeat the repeaters inside the busport (like what is done with emergency services channels in the Northbridge tunnel). They could have a dedicated channel or even a completely separate radio system (digital?) for the busport. I think most of the bus companies that service the CBD have their repeaters on the tall CBD buildings so they might get enough signal down there to work. I know that they do nothing special for the Esplanade busport and it seems to work ok.

Interesting listening tonight, buses calling Bus port Control on normal channels, only one sided conversations I'm guessing persons at the bus port were transmitting on talk around/simplex. Made the dispatchers job a lot harder hearing these calls on the same channel.

What frequency were you hearing this on? I might dig out the scanner and have a listen tonight.

On all three northern carriers Path 490.450/Veolia 490.500/Swan 470.375 there might be others that I wasn't listening to that also service the bus port.

EDIT: Not much regarding the bus port after that night I think that was just because of system malfunctions they were doing things more manually.
