TxID Transmitter FingerPrinter
| | TxID |
Fingerprint? Carrier operated radio transmitters exhibit a unique frequency versus time start-up characteristic before stabilizing on the operating frequency--even radios of the same make and model. This "FingerPrint" can be captured, stored and analyzed. Our exclusive TxID Software, which can automatically Match and Compare up to 256 FingerPrints, and the patented technology of the TxID-1 IBM/Compatible circuit board can help you identify the abusers on your radio system or repeater! Or help you track the number of radios per account on commercial repeaters.
How it Works An onboard fast squelch starts the FingerPrinting process. The voltage on the receiver's discriminator is sampled, digitized and stored. The leading edge of the carrier is then captured, stored and displayed. Other information about the signal is also captured, including DTMF, CTCSS and DCS signals with separate peak deviation readings, and displayed with the FingerPrint.
Features The TxID System can optionally control a tape recorder, capturing all or part of the transmission on audio tape along with the digitally encoded FingerPrint data. Deviation measurements and Spectrum Occupancy features further enhance the system.
Computer-controlled receivers The TxID System works with most FM receivers and scanners. However, when appropriately connected to the ICOM R7000, R7100 or the AOR AR3000 computer-controlled receivers, the TxID-1 can also capture the frequency of operation, as well as set the frequency.
