Other members who said they had problems- zwiller, duane.mosley, rm357, sebjsan in case you want to pm them. I remember one said their problem dissapeared when they moved the transmitter away from the ED. Another said their radio in the garage got interference without the ED being connected to a FM transmitter. Other people said when they connected an FM transmitter the scheduler would malfunction. These are what I saw when I searched transmitter and radio on the site.
