NBN interference

[VK3RX]

Thanks for the links.
A mate in regional Victoria said their AM broadcast band was knocked out by NBN Fixed Wireless from day one. I told him I'd read a couple of years back about a VK7 having the same issue and that the firmware in one of the boxes at that time needed to be wound back to the previous version.
His wife won't let him report the issue. She thinks that an NBN tech fiddling with their NBN electronics might degrade their service 

If I am interpreting the document correctly, if you are (say) experiencing interference from the NBN on 80m, turn off your modem, transmit on 80m and turn the modem back on, and when it syncs to the node 80m might be notched out?

Can't be that simple ....
