Nonsense. The example given by Hilary Claytonsmith in the article
refutes your assertion. BPL interference in the UK would prevent him
from hearing transmissions from the tsunami-devastated areas of Sri
Lanka.  So, unless the power fails in both the sender's and the
receiver's locations, you have a problem.  Also, as any amateur will
tell you (and the Claytonsmith article suggests), amateur radios used
for emergency communications do not run off of batteries exclusively.

Here is a good site for detailed (exhaustive?) info on the BPL
interference subject:

While the ARRL tone at moments sounds a bit like the NRA ("take the gun
from my cold dead hands"), they offer a wealth of technical info and
analysis.
