Calculation and Usage
The frequency of a radio wave is calculated by dividing the velocity by wavelength. You’ll use the frequency range from 420 – 450MHz for ham radio operators. The 2-meter amateur radio band comprises frequencies from 144 MHz to 148 MHz. Data to be transmitted is frequency modulated at the transmission and is demodulated at the receiver side. You can download FM radio apps to access live and local radio stations from your phone.
Licensing and Regulations
You’ll need to work with an FCC frequency coordinator and complete an FCC form 601 for a business radio license. GMRS radios share a frequency band with FRS near 462 and 467 MHz. The FCC has designated that frequencies from 136-174MHZ will be assigned to land mobile radios.
Broadcast Bands and Channels
The FM broadcast in the United States starts at 88.0 MHz and ends at 108.0 MHz. The band is divided into 100 channels, each 200 kHz wide. To listen to the radio DAB+, you will need a receiver compatible with DAB+ reception.
Low Power FM and Licensing Costs
One of the beautiful things about low power FM radio is how cheap it is. Many stations get on the air for under $15,000. The applicant must submit an application form for a radio frequency spectrum licence to the Authority, accompanied by the applicable fee.
Frequency Scan Procedure
Follow these steps to run a frequency scan:
- Connect to the receiver(s).
- Start the scan.
- Stop the scan.
- Export scan data to the Frequency Coordination tool.
- Export scan data to a file.
