Squelch control

The Squelch control is probably the most misunderstood control to new scanner users. The way to use this control is to turn the squelch control knob all the up so that you get nothing but static on a channel that is clear (Nobody transmitting at the time) and then turn down the squelch contol until the static goes away and the scanner starts scanning. If you get a really noisy transmission then turn the squelch control down until the noisy transmission goes away. If you cannot seem to hold a clear transmission then turn the squelch control up.

 Keep a Scanner Notebook

Keeping a Notebook of what you hear and on what frequency is very helpful. Taking notes of police codes you hear used and then you can find out what you what those codes mean (you can find police codes on the Internet and in frequency guides) One of the first things to be put on a scanner notebook is a list of what frequencies are stored on your scanner and those frequencies are used for.

 Mobile Use

If you use your scanner in your car you can use an antenna line splitter (you can get one from Radio Shack) to split the antenna line from the car radio antenna to go into both your scanner and into your car radio antenna. You can also get a cigarette lighter adapter that plugs into you car cigarette lighter and then converts the 12 volts D.C. to the right voltage for your scanner.

 Monitoring Trunked systems on a Regular scanner

 To effectively listen to trunked systems you need to keep your finger on the button, The scan button that is. If you program the trunking band frequencies that are used in your area one after another on your scanner you can just press the scan button just as the first transmission is ending so that you can catch the reply when the frequency changes. If your scanner has a bank feature then you can turn off all the other banks of channels to isolate the trunking band channels.

 Progamming a scanner without having the instruction manual

 If you bought your scanner second hand and you didn't get the instruction manual and you need to know how to program frequencies into your new scanner try one of the following procedures:

• Press manual until you get to the channel that you want to program, key in the frequency that you want on that channel and then press 'E' or 'enter'

• Press manual until you get to the channel that you want to program, press 'pgm' or 'program' key in the frequency that you want on that channel and then press 'E' or 'enter'

One of these procedures will work on most scanners. If you still can't program the scanner then the scanner should be serviced.

Step 1:

• Take 2,953 and divide it by the frequency in Megahertz that you want tolisten to (eg. 2953/144Mhz = 20.5 inches). This is 1/4th of a wavelength in inches. Now cut sections of thin copper wire to this length.

Step 2:

• Take 8,859 and divide it by the frequency in Megahertz that you want to listen to (eg. 8,859/144Mhz = 61.5 inches) This is 1/2 of a wavelength inside of 72 ohm RG-59 TV coax. Obtain a lenth of this stuff and cut it to an odd multiple of the number of inches you got in step 2 (eg. 1 x 61.5; 3 x 61.5; 5x61.5; 7 x 61.5 et cetera, et cetera, depending on how long you need.

Step 3:

• I know "solder" is exclusively a noun and NOT A VERB to many people, but this step requires you to SOLDER SOMETHING! strip the end of the coax and solder one of the wires from step 1 to the center conductor and the other wire from step 1 to the outside shield. MAKE SURE THEY DO NOT TOUCH.

NOTE: Use really thin copper magnet wire and bare the enamel before soldering.

Step 4:

• Tape your antenna to any non-conductive surface like your wall, your bathtub, your window, your dead tree in the back yard, your china cabinet, I don't care BUT DO IT THE FOLOWING WAY: take the wire you soldered to the center conductor and tape up [by up, I mean in the vertical direction facing the sky, the place where airplanes fly, the clouds, heaven or the home of the holy deity of your choice.] take the wire you soldered to the outside shield and tape it down [down is the opposite direction of up. It is where the dirt, sand, soil, gravity and stuff comes from.]

Step 5: The final step.

• Go to Radio Shaft and buy the connector to fit your scanner. Do you see where your antenna is taped up and down? Good. Now go to the other end and connect your adapter, after all I don't want you to ruin all that hard work. Gratulieren meinen Freund oder meine Fruendin! You have successfully built a 72 ohm vertical dipole antenna. Now, you can plug in your scanner and enjoy the 3 or 4 dB gain over using a rubber duck.
