I understood [….], that the 2CH transmitter on 1170 kHz was supposed to close down on 10 June in the evening?
There still is sports programming hear via Sydney Kiwi today.
What is then heard in Sydney today:

Yes 1170 kHz is still very much active in Sydney; it is now ‘SEN 1170‘ airing an all-sports format as discussed above. There are no plans to switch off this service as far as I’m aware. 2CH left 1170 kHz over a year ago now.
