Interesting to hear about this. What I got was a 'workaround' which did not solve the real problem of interference emanating from the NBN equipment. instead December 2015 I was provided, by NBN Co, with a new digital radio which could be precisely tuned to the local AM ABC station in SW WA and an external antenna. This set up worked ok but only whilst the radio was plugged into the external antenna. I can't use the radio anywhere else in the house because I get the interference from the NBN Fixed Wireless Broadband set up. I noticed this as a problem earlier this year when I wanted to listen to the radio elsewhere in the house whilst there were ongoing bushfires in the region.
In the past couple of months AM radio reception has deteriorated and I constanly get background noice sometimes to the extent that I turn off the radio. I can tune the external antenna, which can improve the signal to noise ratio but there is still static at all times - unless i turn off the NBN Fixed Wireless Broadband, of course. Turning off the NBN is pointless because then I obviously don't get internet, emails, nor wifi in the house.
Thanks for letting me know about the ODU and IDU "Rev 1b" versions. How can one get in touch with the NBN engineering folk?
We have another bushfire season coming up within three months and it is imperative that we have as many options as possible to access information.
