Yaesu FT-65 5W Radio

TheFT-4XE is a handheld dual-band radio with a maximum power of 5 watts , with the ability to be reduced to 2.5 watts and 0.5 watts , allowing the power to be adjusted according to the user's needs and conditions.

The 1965 mAh Li-Ion battery provides up to 9 hours of operation. The kit includes a charger that allows the battery to be charged in 3.5 hours. A 1-watt speaker provides high quality sound reception .

The radio meets the requirements of the military standard MIL-STD-810 C, D and E, which defines its endurance in extreme conditions. IP54 protection class provides protection against the ingress of dust and e protection against the stream of water flowing from different directions with an intensity of up to 12.5 liters per minute.

The radio is also equipped with various communication and programming options, including VOX operation with an optional microphone kit, computer programming and cloning of settings from another device. Safety features incorporated into the model include an alarm, channel lock and automatic power off.

The ARTS function, or Automatic Range Transponder System, is an automatic range checking system used in radios. This feature allows the radio to automatically notify the user when the radio is out of range of another radio configured with the same ARTS system. This feature is particularly useful in professional situations where a group of people must maintain continuous communications over a wide area, such as a construction site, major events or search operations, allowing rapid response to the loss of communications with any member of the group.

DTMF (Dual Tone Multi Frequency)operation is a feature used in radios to control various devices or access telecommunications systems by generating specific tones. Each key pressed on the radio's keypad generates a unique combination of two tones at different frequencies, allowing commands to be transmitted in audio form. The DTMF system is commonly used in a variety of applications, such as remote gate control, activating alarm systems, or dialing telephone numbers. It also allows remote activation and deactivation of functions on base stations and other radios that support this feature. With DTMF operation, users can perform a range of activities without direct physical contact with the target device, which is particularly useful in conditions where direct access is difficult or impossible.

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Code Squelch) operation are two methods used in radio communications to filter unwanted signals and reduce interference. They allow the reception of only those signals that contain the appropriate tone or code, which is particularly useful in environments where multiple users operate on the same or similar frequencies. Both features are extremely helpful in keeping the communication channel clear and preventing accidental reception of transmissions from unwanted sources, which is especially important when using radios in professional and hobbyist radio.

The radio'sQRK (Quick Recall Keys) are quick-access buttons that allow the user to manipulate important device functions quickly and easily without having to browse through menus. They can be configured to perform specific actions, such as quickly recalling a specific frequency, activating the scan function, or activating VOX mode.
