Well it looks like it might well be a moot point.
I realised I had a USB audio interface I could experiment with -a USB mixing desk- so wandered out to the shed.
It looks like the NBN FTTC Modem that was installed on Friday is simply a source of Wideband Noise on the HF bands. The waterfall is hundreds of thin vertical lines.
Power the modem down or unplug it from the lead-in and magically it goes away.
The NBN isn't even fully installed and is already causing issues.
I didn't get around to testing the audio interface.
