Quansheng UV-K5 FCC/CE/NORMAL - How to swap from one another

The UV K5 radio is a versatile communication device that offers multiple operating modes to cater to different frequency bands and regulatory requirements. Each mode corresponds to specific transmitting bands and frequencies, allowing users to adapt their radio usage based on their location and intended applications. Let's delve into the various operating modes and the purported key combinations for switching between them and enable aditional bands.

FCC version transmitting band Frequency: UHF420∽450MHz/ VHF144∽148MHz

CE version transmitting band Frequency: UHF430∽440MHz/VHF144∽146MHz

NORMAL version transmitting band Frequency: UHF400∽470MHz/VHF136∽174MHz

The FCC version of the UV K5 is designed to comply with the regulations set by the Federal Communications Commission (FCC) in the United States. This mode provides access to UHF frequencies ranging from 420 to 450MHz and VHF frequencies from 144 to 148MHz. 

The CE version of the UV K5 adheres to the requirements specified by the Conformité Européene (CE) for European countries. It operates on UHF frequencies between 430 and 440MHz and VHF frequencies from 144 to 146MHz. 

The NORMAL version of the UV K5 offers a broader range of operating frequencies, making it suitable for general use in various regions. It encompasses UHF frequencies spanning from 400 to 470MHz and VHF frequencies ranging from 136 to 174MHz. 

How enable TX bands/region

To enable set radio to off, hold down both the PTT and top side button, turn the radio on and this will reveal a secret menu. 

Under F-LOCK you can select FCC/CE/OFF. 

Under 200/350/500 you could enable TX on additional bands, example enable 200TX for 220 Mhz HAM band.

If you desire an extreme modification to allow the usage of 18-1300 MHz, you can refer to the guide on installing the modified firmware.

Disclaimer: Before activating and using the extended transmission feature, it is essential to thoroughly check and comply with local laws and regulations regarding frequency usage. Operating outside authorized frequency ranges without proper authorization may result in legal consequences. It is the responsibility of the user to ensure compliance with applicable laws and obtain any necessary licenses or permits before engaging in extended transmission activities.
