RADIO SCANNER sa RADIO SCANNER ANTENNA x SCANNER (RADIO) xx EAVESDROPPING DEVICE xx RADIO A $5 scanner circuit for the Wilson WE-800. Scanner silencer. This simple carrier-operated switching circuit eliminates the squealing and howling feedback that's caused by scanner-transceiver interaction. Spectrum monitor watches nine channels and tells which ones are clear. Est. cost: $50. CB band sweeper. Tunes your transceiver automatically and continuously from the low to the high end of the band to monitor every CB channel. CB band scanner monitors the entire CB band automatically, one channel at a time, without turning the dial on your receiver. Flashing lamps indicate the channel being received at the moment. Electronic VHF ham band scanner. How to convert the Realistic PRO-6 VHF Hi-Lo Pocket Scanner into a 4-channel scanner for CB radio. Channel changer soups up your scanner. Add twelve more frequencies to an existing 8 or 10 crystal scanner. The additional frequencies must all be from the same frequency band. Unit requires no external power supply. Convert your AM/FM pocket radio into an aircraft scanner. Scan-Mate connects between your scanner and a cassette recorder. When a signal is present at the scanner's output, the Scan-Mate starts the recorder and feeds the scanner's signal to the recorder's microphone input. The recorder is turned off when the signal goes off. Scanner chatter. Part 1. What is available in modern scanners and tips on their use. Includes a homemade coil for AM broadcast reception. Scanner chatter. Part 2. Practical procedures and important antenna tips. Getting more from your scanner. Some tips. Interfacing the Apple II computer to the Yaesu Model FRG-9600 vhf/uhf communications receiver to increase the number of frequencies which can be scanned. Requires the optional Yaesu Model FIF-65A interface. The program listing is provided. Scanners and scanner antennas. An overview of available programmable scanners, which frequencies to listen on, the use of antennas, and legal aspects of eavesdropping. Scanner converter. This simple device down-converts signals in the 800- 950-MHz band so that an ordinary scanner can hear them. Est. cost: $50 (kit). Complete scanning with the Realistic PRO-34 scanner. Hardware modification allows tuning 806-960 MHz as a continuous band. A listing of radio frequencies used by federal, state and local law enforcement agencies in South Florida (Dade and Broward Counties). Scanning the bandido band. Using your scanner to listen in on radio pirates operating in the 30 to 50 MHz frequencies. Tips on modifying the Realistic PRO-2004 and PRO-2021 scanners to receive more bands. Living with the Realistic PRO-2005 scanner. How to adapt this scanner for mobile use. How walls have ears. Using a scanner to eavesdrop on wireless intercoms, baby monitors, and similar low-power FM devices. Scanning tricks of the trade. How to receive radio signals in "impossible" locations. Passive repeaters, radiating coax, and other exotic devices. Adapt a scanner to eliminate the annoying 2kHz pilot tone when listening to mobile phone frequencies (454 MHz). The tape-H trick. Shortcut to recording and logging frequencies. By aiming a camcorder at the frequency readout of your scanner and plugging the earphone output into a VCR's audio input, you can record six hours (or more) worth of scanner audio accompanied by frequency information. Scanner soup-ups. How to upgrade some older scanners to use an AM detector, receive SSB, handle inverted speech, etc. How to get the most out of scanning. Tips on selecting a scanner and antenna. A traveling scanner. Advice on selecting a portable, battery-operated handheld scanner. Using radio scanners while flying on commercial aircraft. Some tips. VHF/UHF scanning monitors. A comprehensive buying guide. Plug-in accessory upgrades a pocket scanner by adding power-supply protection, backup power, trickle charging and other features. Build the auto scan which is connected between a scanner and a cassette recorder. When an audio signal is detected, the recorder is activated. Scanner Companion eliminates the annoying hiss between messages. Build the scanner silencer. A carrier-operated switching circuit eliminates the squealing and howling feedback that's caused by scanner-transceiver interaction. Mutes the scanner audio whenever you are transmitting. Build the scanner converter which down-converts signals in the 800- to 950-MHz band so that an ordinary scanner can receive them between 400 and 550 MHz. Est. cost: $50 (kit). Choosing the right scanner for your needs and budget. DTMF computer interface. Decode DTMF tones picked up by your scanner and display that information on your computer screen (or save it to memory) with this simple scanner-to-computer interface circuit. Computer CB scanner. Use your Commodore C64, SX64 or C128 computer to monitor up to 40 CB channels and display a bar graph showing the level of activity. Requires construction of an interface circuit between computer and CB radio. Scanner converter. Upgrade your scanner to receive signals in the 800-900 or 900-1000 MHz bands. Est. cost: $68 (kit).
