  • Scanner info - Alfakom electronic
    the same frequency e g my county sheriff uses the same frequency as Chicago Police located about 60 miles away I want to hear my sheriff s transmissions but don t want the scanner to stop on or listen to Chicago Police transmissions This is especially a problem when radio propagation is good e g during a band opening when reception range is temporarily increased 2 Combat intermodulation interference Helps keep out intermod and image interference from strong pagers and other signals which are not transmitted with a matching code 3 Ignore scrambled transmissions Many federal law enforcement agencies FBI Secret Service etc and some local police agencies employ digital voice scrambling which sounds like white noise and is annoying to hear The CTCSS or DCS code is sent only when the station is transmitting unscrambled or in the clear You can program federal frequencies along with the proper code into your decoder equipped scanner so you won t have to listen to the scrambled mess and only hear their transmissions when they are unscrambled CTCSS also goes by various tradenames Motorola s PL Private Line GE s Channel Guard and RCA s Quiet Channel Motorola uses the tradename DPL Digital Private Line for its digital coded squelch Hur bestämmer jag CTCSS or DCS koden There are a few ways to determine the CTCSS or DCS code transmitted by a station 1 Use an outboard CTCSS DCS reader which must be attached to the discriminator output circuitry inside the scanner The reader has an LCD or LED display which indicates the code when a station transmits I use a CSI model CD 1 Communications Decoder Unit an an excellent reader which sells new for about 200 Connect Systems Inc Ventura CA 800 545 1349 www connectsystems com 2 Many of the ScannerMaster guides as well as scanner club newsletters print the CTCSS codes used by transmitting stations 3 On some scanners equipped with the CTCSS squelch you can program into memory the frequency of interest Then you tune slowly through all the different CTCSS and or DCS codes until the squelch opens and you hear the dispatcher talking This is a slow process and the station has to keep transmitting during it 4 A slow brute force method is to program the same frequency but a different CTCSS code into several channels and see where your scanner stops 5 In some cases I ve actually examined the walkie talkies I want to monitor and found the CTCSS code printed on a label on or inside the radio CTCSS Tones CTCSS tones sometimes called sub codes or privacy channels uses a sub audible tone to prevent other people using the same channel from interrupting your conversation Most radios have 38 available CTCSS Continuous Tone Coded Squelch System codes which can be individually assigned to any of 14 channels for a total of 532 combinations Once activated the sub audible tone is transmitted each time the PTT push to talk button is pressed Additionally the radio only responds to incoming signals using the same CTCSS tone The above text was taken from the GE 35840 user s guide NOTE This feature does not keep anyone from hearing your conversation It simply filters out anyone s transmission that does not have the same channel code combination set Scanner antenner All scanners come with a built in antenna permitting reception up to about 20 miles or so Portable scanners are supplied with a helical spring shaped antenna covered by rubber The rubberized antennas furnished with current models are too stiff and place stress on the antenna jack Older scanners to be supplied with more flexible antennas I prefer these alternative antennas for use with portable scanners 1 The Icom FA 1433B dual band flex antenna a thin and very flexible rubber antenna is slightly longer than a stock heliflex but provides better performance 2 The Austin Condor is a 12 long rubberized antenna available for about 30 While considerably longer than the stock antenna and the FA 1443B the Condor is very flexible and provides VHF high band reception superior to both It is not designed to cover the VHF low band but will allow reception there at least as good as shorter antennas The Austin Condor is available from Grove Enterprises 3 The Thin Stick is an 18 inch telescoping antenna for extended range It is made in USA by Smiley Antenna Co Inc and is designed to cover both the 2 meter and 220 MHz bands but its variable length means it can be adjusted for optimum performance on other bands What makes the Thin Stick different from an ordinary telescoping antenna is the spring between the antenna and the connector portions The spring absorbs most of the impact if the antenna collides with an object The street price is about 17 and it is available from Amateur Electronic Supply Milwaukee and other retailers Outdoor antennas like the Channel Master 5094A available from Amateur Electronic Supply or Antenna Specialists AV 801 recently discontinued can extend reliable reception to 50 miles or more depending on terrain If you do use an outdoor antenna be sure to disconnect and ground it during storms and when not in use to avoid a lightning hazard Discone and ground plane type antennas can be more prone to cause scanner damage due to static charge buildup because they are not at DC ground Koaxialkabel If your antenna installation requires more than 50 feet of feedline use RG213 U or high quality RG8 U coaxial cable RG213 U e g Belden type 8267 has a non contaminating jacket and will last longer Each has an outer diameter of about 13 32 Similarly sized Belden 9913 cable and clones have lower attenuation but are difficult to bend require special connectors and can accumulate moisture inside because they are hollow If you must use a small diameter cable for long runs use RG6 U Avoid RG58 U 7 32 OD due
