Will contact you off list, Mark when I find articles, and make and model of homeplug (cannot get to neighbours house until next weekend
Thanks for the info so far and quite happy to continue this off-list.
Just as a postscript, I did a quick Google for the Radcom articles (didn't find them)but it lead me to this interesting Homeplug + Amateur Radio thread: http://www.digitalspy.co.uk/forums/showthread.php?t=477821 (The thread is about homeplugs, the radio part of the thread starts in the last couple of posts on the first page (of three)).
Interesting that there are some people who would be affected if there were a general problem saying that they use them without problem, so I suspect that any problem will relate to manufacturer+model, or maybe a manufacturing fault, but that makes me no less intruiged to follow this up. (Interesting thread on Homeplugs anyway.)
