My Dalkin FM transmitter was not that successful, within Kansas City, which probably has an average number of radio stations across the dial. We have had a consistent experience with the FM transmitter. We will get good IPod reception for a while, but then abruptly a radio station will kick in and loudly substitute for whatever is playing on the IPod. It is jarring.
After a time, we came to know where certain radio stations would interfere with the IPod music. At 75th Street and the I35 exits in Overland Park, a fire and brimstone preacher's shouted sermons will come on literally in mid-note of the music playing on the IPod. The sermons come in at a volume louder than the IPod's music. That is a shock to the system.
In some entire sections of the metro area, the IPod music comes on in a faint, static filled way, like you are getting a weak radio signal.
