I have the FM Transmitter ordered for my father, so that he gets his music from the PC to the radio. I read in advance good via the transmitter, but I was, after everything was connected disappointed. When the transmitter in operation and frequency was found, I asked this one on the radio. I only heard noise, even though the radio was more just a room. Nagut I thought to myself, I'll buy a USB extension cable and add the thing into the same room .... hey this time rang out music from the radio, but it began to rustle when you move. So I took a long antenna cable, laid it under the skirting board and put it next to the transmitter, and behold a clean sound without noise or interference :-). So if you want to overcome a greater distance than 1 meter should leave it alone, or should it so as I do, but that can not call it wirelessly. Because the software is better than that from the previous transmitter, there's 1 star from me .... after all you have anything improved
