  • The difference between the UHF band and the VHF band
    The difference between the UHF band and the VHF band on August 19,2023.
    1. VHF (144.00 ~ 148.00MHz) This is the typical VHF band, which is a very active local mobile communication band. The ionosphere of this frequency band signal basically does not produce reflection, the radio wave is mainly transmitted by direct wave line-of-sight, the transmission encountered a large building or mountain, will produce reflected waves, therefore, can only be used as a two way radio close-range communication. This band of antennas is the highest amateur radio production rate, there are a variety of high-gain directional and omnidirectional antennas, there are car mobile whip antennas and small handheld antenna and so on. The interference in VHF mainly comes from cordless phones, BP sets and other base stations. This frequency band is the dedicated frequency band of our HAM, while UHF is the common frequency band. 2. UHF (430.00 ~ 440.00MHz) It belongs to the UHF band, and the direct wave propagation is worse than that of the VHF, and the penetration of the UHF is better than that of the VHF, so there are more UHF in cities with high-rise buildings. But at the same time, the attenuation of the air is larger than that of the VHF, which is not suitable for long-distance communication. When using longer cables, the attenuation of the cable to the signal should be considered. Due to the high frequency of this frequency band, the noise is small, and the manufacturers compete to launch a number of small and fully functional frequency band antennas can be relatively small, and can be set on the car navigator, therefore, this frequency band mobile communication is very active. In order to solve the problem of close communication distance, many amateur radio operators set the relay platform at a high altitude, with the help of forwarding differential signals, can greatly increase the communication range, as long as the enthusiasts use a small power and simple antenna, they can and distant radio QSO. In the summer and other seasons of unstable weather, radio waves refracted back and forth between the three layers of the atmosphere, and the attenuation is very small to the distance. There are also phenomena such as meteor trail reflection and tropospheric scattering, which will also make the radio waves in this frequency band propagate beyond the visual range. VHF and UHF are the most interesting, useful and challenging bands for amateur radio operators, so they are currently used by amateur radio operators in a wide variety of situations. Many people love the convenient way to communicate on the VHF/UHF band. It makes local communication between enthusiasts and friends very convenient, whether at home or in the car, or while traveling or working. There are also some people keen on long-distance communication, long-distance communication and local communication in the dissemination of a big difference.

  • What is the VOX function of two way radio
    What is the VOX function of two way radio on August 12,2023.
    The Voice-Activated Transmission (VOX) function is a feature found in many two-way radios that enables hands-free operation. When the VOX feature is activated, the radio automatically transmits your voice without the need to press any buttons. This allows you to communicate freely and conveniently, especially in situations where manual operation may be cumbersome or impractical. Here's how the VOX function typically works: Activation Sensitivity: The VOX feature allows you to adjust the sensitivity level to control when the radio starts transmitting. Higher sensitivity settings mean the radio is more likely to detect even low-volume sounds and begin transmitting, while lower sensitivity settings require louder sounds to trigger transmission. Microphone Detection: Two-way radios with VOX employ a built-in microphone that senses sound waves. When you speak into the microphone, the radio detects the audio signal and initiates transmission. Hands-Free Operation: With VOX enabled, you don't need to press and hold a push-to-talk (PTT) button to transmit your voice. The radio automatically switches to transmit mode as soon as it detects your voice, allowing you to communicate without physically interacting with the radio. Transmission Threshold: To avoid unnecessary transmission triggered by background noise or unintended sounds, two-way radios with VOX typically include a transmission threshold. This threshold establishes a minimum sound level required to activate transmission. It ensures that only deliberate and audible speech triggers the radio to transmit, reducing unintentional transmissions. The VOX function is particularly valuable in situations where your hands are occupied or when manual operation of the radio may be inconvenient, such as when hiking, climbing, or participating in hands-on activities. It allows for seamless and uninterrupted communication by eliminating the need to press a button each time you want to transmit. It's important to note that when using VOX, you should be mindful of your surroundings and the potential for unintended audio triggering transmission. Loud background noises, wind, or other participants' conversations may activate the VOX feature unintentionally, leading to interference or disrupted communication. Adjusting the sensitivity level to an appropriate setting and periodically testing the VOX function in your specific environment can help optimize its performance and minimize unintended transmissions.
