This could get tricky...

Quite tricky. No local intercoms and the distance between dwellings is rather larger than suburban NSW too boot. The power point tester arrived today, thanks for the link & recco, all points in the room have been tested as well as any power boards. All are AOK.
I've ordered ferrite beads as the next step...oddly largely O.O.Stock in many places in Oz and LOTS of bad reviews for most online sellers (mainly masquerading as local but actually in mainland China).
