Jim,
A very tough problem indeed. There always seem to be power lines 
paralleling the county line roads, so they're especially hard to 
avoid for an ILQP county line operation. Obviously a noise blanker 
such as the one in the IC-706 is a good start but it's not completely 
effective. I suspect there's a lot of variance in the noise spectra 
of different power lines.

I wonder how good the digital noise blanker in the IC-7000 is. Icom's 
website says "The NB level and width (blanking duration) are 
adjustable in 100 steps." Of course, it's hard to dink around with 
the settings when you're flying down a gravel road.

Anyone out there with an IC-7000 who can comment on the effectiveness 
of the digital noise blanker for power line noise?
