Firstly, _Great Work_, Larry!  I too trust that you will keep us
up-to-date with your observations. 

A few of us (including Derek, G3GRO and, I believe, Finbar, EI0CF) have
been working with interference cancellers of various sorts.  I have had
great success with a canceller based on a design by VK5BR.  Details of
my experiences when using a canceller (to deal with local electrical
noise) can be found at:

Also, a paper written by Derek, G3GRO entitled 'A Simple Signal
Canceller For 136Khz To Combat Loran or Other Noise Sources' can be
found at:
