Thanks everyone for the very helpful advice, suggestions, circuits and 
links, both on and off reflector. (The several 'reduce power' suggestions 
were not so helpful, hi)

Our wired phone system is ancient and mostly redundant cos we use a DECT 
phone 99% of the time - it is so old that there is no BT 'master socket' 
which baffled the BT Openworld installer in August when he came to check our 
line. The ringer wire is not connected anywhere.

About 50W on 1.8MHz is enough to cause problems, so I'll get a new-style 
faceplate fitted with only one phone and the ADSL router connected to it, 
remove all the redundant wiring, then try some filtering.
