Choosing the Correct FCC License Form for UHF Frequencies: A Comprehensive Guide
When it comes to using radios in the UHF (Ultra High Frequency) band, selecting the appropriate FCC (Federal Communications Commission) license is essential. This guide will help you navigate the intricacies of UHF frequencies, particularly those used in the context of Midland's MB400 radio, and understand the different licensing requirements.
Understanding Midland's MB400 Radio and UHF Frequencies
Midland's MB400 radio operates within the UHF frequency range, and it provides a list of specific available frequencies rather than a broad range. This approach is quite unique, as most other radios, such as those from Kenwood, offer a range like 403 - 430 MHz or 430 - 470 MHz.
Among the specific frequencies listed for the MB400 are 464.500 (Brown Dot) and 464.550 (Yellow Dot). These are itinerant frequencies, designed for non-stationary operations. However, the corresponding repeater inputs (469.500 Brown Duplex and 469.550 Yellow Duplex) are not listed, suggesting that this radio might not be repeater-capable. Additionally, keep in mind that you are limited to five watts on these frequencies, making it unnecessary to purchase high-duty cycle repeaters unless your radio can handle them.
Licensing Requirements for UHF Frequencies
To use these frequencies legally, you need to obtain the appropriate FCC license. The specific type of license you need depends on whether the frequencies are itinerant, fixed, or part of the Business/Industrial pool.
Itinerant Frequencies
For itinerant frequencies, such as 464.500 and 464.550, you can select a statewide itinerant or a nationwide itinerant license. Contrary to popular belief, these frequencies are not license-by-rule and do require a license. You cannot get exclusivity on these frequencies, but they can be utilized by individuals or businesses without needing to coordinate with other users.
Fixed Base Operations
Fixed base operations like 477.850 (Silver Star), 477.875 (Gold Star), 477.900 (Red Star), and 477.925 (Blue Star) require a different approach. These frequencies can be utilized for fixed base operations and are low-power frequencies allocated by the FCC Regional Coordinator to several users in a smaller area. They are also often misinterpreted as license-by-rule frequencies, which is incorrect.
Business/Industrial Pool Frequencies
The remaining available frequencies, such as those in the 462 - 469 MHz range, are part of the Business/Industrial pool and will require licensing and coordination with the FCC. The cost for a single frequency license is $479/year, or $579/year for a repeater pair.
Alternatives to Traditional UHF Licensing
While obtaining an FCC license is the safest and most legal option, there are alternatives if you prefer not to deal with the bureaucratic requirements. Some low-power 900 MHz options, such as Project 25, are available. However, these are shared with ham operators and ISM (Industrial, Scientific, and Medical) equipment, so be aware of potential interference.
Family Radio Service (FRS) and MURS (Multi-Use Radio Service) are also options. FRS offers 22 UHF frequencies, with the ability to transmit up to two watts in narrow band on non-interstitial frequencies and .5 watts on interstitial frequencies. MURS, on the other hand, has five VHF frequencies, commonly used by big box stores and others, with a legal output of two watts and the ability to use a detachable antenna.
Conclusion
Whether you're using a Midland MB400 or another radio, understanding the different licensing requirements for UHF frequencies is crucial. It's important to choose the appropriate license to avoid potential fines and ensure legal and safe operation. Always choose to play it safe and obtain the necessary licensing when operating UHF radios.
Choose from the options available, but remember, compliance with FCC regulations is essential to avoid any legal issues and ensure the smooth operation of your equipment.
