Query: It doesn't work.

This device arrived, nicely packaged and all but it doesn't work.First I tried it out by connecting it to the headphone output of my computer (I did check that something was playing). Next I plugged it into the headphone socket of an MP3 player. Using the headphones, I confirmed that something was playing. I even held the DLO Transmitter right next to the receiving radio's antenna and tuned the radio to surrounding frequencies in case the display was inaccurate.To check that it wasn't the radio or the DLO battery, I tried it in the car, using the car charger. Still no go, so I removed the battery and relied on the charger alone. Same result.What a disappointment! I see that many others have had similar experiences with this product.
