Use baluns at antenna feedpoints. This will keep the feedlines from
radiating and talking to each other.
Reduce coupling via the mains power by wrapping power cords through
a large ferrite core. Use 70-series (low-frequency) ferrite, 5-10
turns. Put the core close to the rig.
Select rigs which have a wide dynamic range. Use attenuators if
available and feasible. If possible, don't use preamps.
Run QRP (< 5W). We never have trouble working > 300 stations using
5 watts and gear, including antennas, we can carry on our backs.
A nice side benefit is the lack of roaring generators. (With a
generator, we never would have heard the cougar "cat concert" at
