Ground Loop "Hum" Using BT Modulator

[ChrisW6ATV]

I did not see this specifically mentioned in this topic, so here is one thing that may have worked with this problem for me: Try plugging the modulator into one of those "grounding adapters" that have only two prongs, to eliminate the ground connection from the modulator to the building. Then, use a DVD player or VCR (also with its two-prong cord) as the signal source. (Do not have the VCR connected to any cable box or antenna system, just standing by itself.) Let me know if you tried this already.
