Ground Loop "Hum" Using BT Modulator

[old_tv_nut]

Same hum bar on any other TVs using an antenna? How do you know it's not your TV?

Should have also added coax output of modulator -> any kind of antenna; some kind of antenna -> TV antenna input on modern flat panel: hum bar
Same problem on all TVs in the home, vintage and modern alike.

Hiya John--sorry to hear of the continued woes. My humbar was different than the one on your video link. Perhaps it is not a transmission issue, but a circuit issue in the B-T. It would be interesting to see whether or not a different B-T unit would have the same fault, in the same room and set-up. Could the interference be external? (doubtful I feel)
