If you read it carefully, I told you WHY those frequencies are used, HOW they are used, and to what purpose. But if you ever interfere with the military and they DO decide to go after you, you will be in a world of hurt! The CAP fellows don't like it, and they, like the hams, will pursue you-with assistance from USAF Frequency Management. Sure, you *may* never get "caught" down there. Some of them, including one in my local area, got CAUGHT and heavily fined for interferring with emergency traffic. Each distinctive mode and frequency is used for a specific purpose including digital traffic, and also serves to thwart newshounds and scanner listeners whose FM scanners won't decode SSB.Īctual search and rescue missions have been interrupted by people who thought those "freeband" frequencies were there for the taking. One hundred Fifty watt SSB is used for mobiles for ground search activity out to about 40-50 miles. They are used for on-base things like messenger and runners, tote board for aircraft and vehicles, command and control between the communications section and the Incident staff. Such frequencies at low power 5 watt level provide relief for VHF circuits for air-ground, air-air activity. Yes, they DO use them for search support. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication however, various radio propagation conditions may intermittently allow communication over much greater distances.And there ARE *some* agencies such as Civil Air Patrol that have frequency assignments on 26 megs. Transmitter power is limited to 4 watts in the US and the EU. Users on a channel must take turns talking. The radio is normally in receive mode to receive transmissions of other radios on the channel when users want to talk they press a " push to talk" button on their radio, which turns on their transmitter. Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ( "ham" radio). Citizens band radio (also known as CB radio), used in many countries, is a land mobile radio system, a system allowing short-distance person-to-many persons bidirectional voice communication among individuals, using two way radios operating on 40 channels near 27 MHz (11 m) in the high frequency (a.k.a.
