1.easy to use If you’re new to two-way radios, or you have budget constraints, you may not need an advanced technical model. For less technical users, radios with pre-programmed channels will be the easiest way to begin radio communication. For these entry-level radios, we recommend one person on the team coordinate the radios and program…

The dipole antenna or dipole aerial is one of the most important and commonly used types of RF antenna. The dipole aerial or antenna is widely used on its own, but it is also incorporated into many other RF antenna designs where it forms the radiating or driven element for the overall antenna. The dipole…

Retevis manufactory a new DMR Ailunce HD1, it has the large capacity of the memory card could memory 50-1000 contacts. which is loved by many Amateurs.

The process of separating or extracting the modulation from a signal is called demodulation or detection. For amplitude modulation, the process of demodulation or detection can be accomplished very simply using a diode, or it may be achieved in other ways that provide more effective demodulation of the waveform. As amplitude modulation is still widely…

In order that a steady radio signal or “radio carrier” can carry information it must be changed or modulated in one way so that the information can be conveyed from one place to another. There are a number of ways in which a carrier can be modulated to carry a signal – often an audio…

Here we interview customers about their radio stories, for helping you know better of our radios and get right ones you need. Today let’s know RT3 better .

Frequency modulation is widely used for radio transmissions for a wide variety of applications from broadcasting to general point to point communications. Frequency modulation, FM offers many advantages, particularly in mobile radio applications where its resistance to fading and interference is a great advantage. It is also widely used for broadcasting on VHF frequencies where…

RT23 has a lot of functions, cross band repeater, dual receive,dual ptt,360 degree channel,one touch setting same CTCSS/DCS etc. Today i will intorduce how to realize dual ptt. Most of radios can’t setup two ptt. for example BH-F8HP. When you push ptt, the radio transmit main channel frequency. If you want to transmit sub channel…

Today, we will check the dual receive function of Retevis RT23. If you have the RT23, You may fell not clear with 35(VOL-MODE). Look the picture bellow. RT23 has another special functions. It can receiving two signals at the same time. Ordinary radios like BF-F8TH can “watch” two channels. Monitor two different frequencies(even on different…
