The IC-F27SR professional Licence Free Two Way Radio is the successor to the best selling IC-F25SR and retains the simplicity, functionality and build that made the original so popular. However, there have been some big improvements including a smaller and lighter body, 800mW loud and intelligible audio, built-in VOX function and several new scanning and security features. To top it off, the IC-F27SR includes highly efficient circuitry that provides up to a massive 35.5 hours of operating time with the supplied BP-265 2000mAh Lithium-Ion battery pack.
