Neither intermod product can be nulled toward either transmitter site with the Faraday shielded loop antenna incorporated into the field intensity meter.
Yep, that pretty much rules out either of the plants as part of the

The intermod appears to be coming from multiple, multiple sources.
Probably, utility lines, mostly.
Several years ago, AC0C alerted us to the fact that MOVs have been
