Long Range Walkie Talkie Module 1W 30dBM 5KM VHF(134-174MHz) / UHF(400MHz -480MHz)

I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.

—— Singh from India

First of all I'd like to thank you for you're prompt service. The system now works perfectly. I left a positive response on your web site. I hope it attracts more customers for you.

LS-828-VHF Walkie talkie module


LS-828 is an all-in-one professional walkie-talkie module in small size. It is very easy to use with powerful function. This module has full function of a professional walkie-talkie and can talk with any analog walkie-talkie in the market. With the small size, it can be easily embedded into instrument, portable and handheld device. LS-828 works well in the hot/cold environment with the KDS 1PPM TCXO. The features of excellent antenna match network, good RF amplifier, high RF sensitivity allow its communication easily to achieve over 3Km in open area. Rotary switch for channel selection, EEPROM, Audio Amplifier, RF Amplifier, PTT key, Antenna socket are all included in such a small size module. Besides, all parameters (CTCSS, CDCSS, SQ, Predefined channels etc) can be easily modified either by PC software or command using UART interface. With the embedded audio volume turning circuit, user can only solder a variable resistor on Pin16, Pin17 to adjust the volume steplessly.

There are two frequency bands of LS-828: LS-828-U and LS-828-V. The only difference is the frequency range. The others are same, including module size, interface, software protocol, etc. The two modules’ frequency ranges are: LS-828-U: U band, 400 -- 480MHz, LS-828-V: V band, 134 -- 174MHz
