Here are six audio samples of the Tx3 put through it's paces using a variety of radios. From clock radios to car stereos to battery powered ten dollar Wal-Mart specials. There are over one billion FM radios in North America alone so it's easy to take advantage of this new phenomenon. As always our samples are not altered in any way, what you are hearing is the Tx3 as it transmits to a radio. We recorded the audio using a Panasonic PV-DV 100D video camera. The only microphone used was the mic on the camera. It's simply amazing!
