off depending on the user's preference. Most scanners have a weather radio band, allowing the listener to tune into weather radio broadcasts from a NOAA transmitter. Some scanners are equipped with Fire-Tone out. Fire tone out decodes Quick Call type tones and acts as a pager when the correct sequence of tones is detected. Modern scanners allow hundreds or thousands of frequencies to be entered via a keypad and stored in various 'memory banks' and can scan at a rapid rate due to modern microprocessors. Active frequencies can be found by searching the internet and frequency reference books or can be discovered through a programmable scanner's search function. An external antenna for a desktop scanner or an extendable antenna for a hand held unit will provide greater performance than the original equipment antennas provided by manufacturers. Uses Scanners are often used by hobbyists, railfans, aviation enthusiasts, auto race fans, siren enthusiasts, off-duty emergency services personnel, and reporters. Many scanner clubs exist to allow members to share information about frequencies, codes, and operations. Many have internet presence, such as websites, email lists or web forums.
