@Jim Brown..
What you say is of course true -- you can only kill one at a time. That
said, you can often times choose your target, by adjusting the phasing.
Getting rid of the most offensive noise source will usually allow you to
be reasonably operational again -- my goal.
If you use two antennas that are both capable of good tx performance,
then you have an additional weapon: switching the two antennas around.
You can do this by installing a dpdt switch in the unit and doing a
little rewiring.
The main PITA with cancellers is the time you spend getting the
adjustments right.
Out Dammed Noise!

Note that ANY noise canceller can only work on noise arriving from one
direction at a time. If you have multiple sources, you can kill only
one of them at a time.
