What are 70cm frequencies?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
What frequency is 40m?
The 40-meter or 7-MHz band is an amateur radio frequency band, spanning 7.000-7.300 MHz in ITU Region 2, and 7.000-7.200 MHz in Regions 1 & 3. It is allocated to radio amateurs worldwide on a primary basis; however, only 7.000-7.100 MHz is exclusively allocated to amateur radio worldwide.
What is the 6 meter calling frequency?
Six Meters (50-54 MHz) is known as “The Magic Band” to many of its fans, but the best description I ever heard came from a ham I worked during a frantic summer Sporadic-E opening: “This is a great band if you like having Mother Nature pull your chain.”
Why is it called ham radio?
The word “HAM” as applied to 1908 was the station CALL of the first amateur wireless station operated by some amateurs of the Harvard Radio Club. They were ALBERT S. HYMAN, BOB ALMY and POOGIE MURRAY. … They then decided to use only the first letter of each name and the station CALL became “HAM”.
What is the 75 meter band?
The upper portion of the band, which is usually used for phone (voice), is sometimes referred to as 75 meters. In Europe, 75m is a shortwave broadcast band, with a number of national radio services operating between 3.9 and 4.0 MHz.
What is CW in ham radio?
Overview. Now simply called “CW”, radio communication by Morse code was the only way to communicate for the first decade or more of Amateur Radio. … They were soon replaced by “Continuous Wave” (CW) transmission, using vacuum tube oscillators that were capable of a very pure note.
What is the difference between 2m and 70cm bands?
2m- Good all around band for talking/chatting, but since its VHF, signal travel depends on what’s in its way and the power output of the radio. 70cm- Good band, since its UHF its good to have in the city or around tall buildings or inside of buildings because its wavelength penetrates obstacles better.
What frequency is the 10 meter band?
The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
What is a 11 meter 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. shortwave) band …
What is the 12 meter calling frequency?
The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz).
What is the difference between a CB radio and a 10 meter radio?
A CB radio allows bidirectional wireless communication between 2 individuals via 40 channels near 27 MHz (11 meters) in a shortwave band. 10 meter radios are not CB radios from the start but they can be convertible into one. Legally, no. 10 meters is an amateur radio band.
What are the citizen band frequencies?
Most CB operation takes place within a narrow band of frequencies near 27 MHz. There are 40 channels in this band.
What are GMRS frequencies?
The General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around 462 MHz and 467 MHz. The most common use of GMRS channels is for short-distance, two-way voice communications using hand-held radios, mobile radios and repeater systems.
How far can you talk on 2 meters?
On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
Where are my local ham radio frequencies?
The best way to find local frequencies is to download the app RepeaterBook. It will find your location and instantly tell you the local repeaters around your area. You’ll then program those into your radio.
What are the unlicensed frequency bands?
The US Federal Communications Commission (FCC) has three primary frequency bands designated for unlicensed operation. Unlicensed means the operator of the radios does not need to file directly with the FCC to use the radio. The three frequency bands used for this in the U.S. are the 900 MHz, 2.4 GHz and 5.8 GHz.
Can you listen to ham radio without a license?
You need to be a licensed amateur radio operator to be able to transmit using this radio, but you don’t need a licence to listen in – which is handy for those looking to get into the hobby, or working towards getting a Foundation licence.
How far can a 5 watt ham radio transmit?
So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles.
How high does a ham radio antenna need to be?
A beam type of antenna at a height of 70 feet or more will provide greatly superior performance over the same antenna at 35 feet, all other factors being equal. A height of 120 feet or even higher will provide even more advantages for long-distance communications.
Will a CB antenna work for UHF radio?
An antenna needs to be resonate at the frequency you are transmitting on. That means the antenna used with a CB needs to be designed to work on CB frequencies (26-27MHz). A VHF/UHF antenna isn’t going to be resonate on those frequencies and will perform extremely poorly.
