XMIT_ID allows you to record and catalouge the unique “fingerprint” that is part of every FM radio’s transmission. This can be used for transmitter identification.
XMIT_ID was created because of the interference problems that plague repeater systems. Finding the people responsible can be very difficult. Yes, you can use “direction finding techniques” to locate them. But, in the case of malicious interference, you need to positively identify the transmitter being used. The answer is to “fingerprint” the radio. XMIT_ID will store and compare the fingerprints of a radio. It records the radio’s discriminator audio finger print, then time and date stamps every transmission. This makes XMIT_ID an invaluable tool to anyone having interference problems. This program will help you in gathering evidence to help convict the person(s) responsible. Here are some uses for XMIT_ID:
- To find stolen transmitters.
- To help locate transmitter spurs.
- To help identify illegal users on a repeater.
- To stop cellular phone fraud.
The price of this type of equipment can be out of reach for the average ham. Now with XMIT_ID, and the following equipment list, you can get “Finger Prints” of radios.
- a modified receiver or 9600 baud packet ready radio
- a 386 or better computer
- DOS 5.0-6.22 (Windows 95 needs a lot of tweeking; it can be done)
- VGA monitor
- 1 meg of memory
- Sound card (A real 8 bit Sound Blaster works the best)
