I've just set up my STR-DN1030 Receiver. I get excellent FM radio. But, the device's AM radio is only producing static on all station numbers. The AM antenna (black rectangular device) is plugged into the AM radio antenna port on the back of the receiver. I've tried both direct and auto tuning.
I guess my top theory is that the antenna is broken. But, it looks in great shape, with no wires frayed or disconnected.
