Bob:
I tried this on several bands (namely 40 and 160 meters), with an output
power of 100 watts, and no RFI was noticed.
I can't try the dummy load with my ALS600, because my dummy load only
handles 300 watts.
I think this is telling me that I am getting some sort of RF coming back
down through my antenna systems.

Tom,
What happens when you transmit in to a dummy load?
