What is 72 MHz used for?
72 MHz is a radio carrier frequency used for the operation of radio controlled aircraft in North America. The term “MHz” is the abbreviation of “megahertz,” or one million cycles per second. Modern 72 MHz radio systems operate via a frequency modulated or “FM” carrier signal.
Is 72MHz legal?
YES it is!! In fact a very large portion of AMA members still fly on 72Mhz. Sure, you have to use a frequency pin at the flying site, but the fact is that many times, you may be the only one on your frequency or maybe even the only one at the flying site on 72MHz! So, it is just like having your own private frequency.
What frequency do RC planes use?
RC is permitted in the 2.4 GHz industrial, scientific, and medical (ISM) band using spread spectrum technology from 2.4 GHz to 2.485 GHz. Frequency Identification and Display: 2.0. Frequency control at an RC operating site is necessary to prevent simultaneous operation of transmitters on the same frequency.
How many channels are available for FM model aircraft radios in the US?
50 channels
In the US there are 50 channels in the 72MHz range that can be used for radio controlled aircraft.
How does RC transmitter work?
The transmitter has its own power source, usually in the form of a 9-volt battery. The transmitter enables control through radio waves and the receiver activates the motors. When we press a button on the transmitter to make the RC toy go forward or backward, a pair of electrical contacts touch.
What band is 27mhz?
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-person bidirectional voice communication between individuals, using two way radios operating on 40 channels near 27 MHz (11 m) in the high frequency (a.k.a. shortwave) band.
Can a 72Mhz radio be used at a flying site?
Many of these radios are full-featured sets with lots of programming and model capability. Sure, you have to use a frequency pin at the flying site, but the fact is that many times, you may be the only one on your frequency or maybe even the only one at the flying site on 72MHz!
Is the 72 MHz frequency a good bet?
With so many modelers operating on 2.4 GHz spread spectrum, 72 MHz is a good bet today. Most of the time you will find that you are the only one at the field on 72 MHz, so you have your own private frequency. Isn’t that just as good? 72 MHz is alive and well, but you probably won’t find it at your favorite hobby dealer.
Do you need a frequency pin for 72Mhz?
Sure, you have to use a frequency pin at the flying site, but the fact is that many times, you may be the only one on your frequency or maybe even the only one at the flying site on 72MHz! So, it is just like having your own private frequency.
Is the AMA still on the 72 MHz frequency?
The AMA has not changed its stance on 72 MHz equipment, and will continue to work with the FCC to keep 72 MHz, as well as the other frequencies, available to modelers.
