Xmit_ID (ver 2.61) Abandoned Freeware Xmit_ID analyses the unique fingerprint of a FM transmitter. In order to gather fingerprints, the program requires a soundblaster card, and a hardware connection to a receiver (see: HARDWARE.TXT). Included are some captured fingerprint files so you can explore the program without connecting to a receiver. Note that saved fingerprint files are saved in the same directory as the executable file.
