Re: AM radio
Page 51 of the Samsung HT-X20 receiver says (in very small print) that the unit does not receive AM broadcasts. I don't remember the last time I actually listened to an AM station on any radio. But, for better FM reception, connect the receiver antenna in jack to the television cable via a 75-ohm splitter (read about this on these forums). Excellent FM reception over the funky little FM antenna on the side of the rig (if you have one).
