[BC] BPL flaws

[Rob Atkinson]

MFJ and Timewave each make a phase cancellation box that takes the line 
noise right out.  you put up a little receiving loop for 20 m. outside and 
feed that into the box, which I think sits between your exciter and amp (if 
you have one) so you can transmit through it and on receive it makes the 
line noise disappear.  I used the MFJ one and was amazed at how well it 
worked.  don't know anything about the timewave box.   if you tune around 
you have to readjust the box.  of course getting the noise source eliminated 
is best but this is better than nothing.
