1、This product can meet your requirements, both for walkie-talkie users and hobbyists. It can measure not only the frequency point, but also the subtone. 2、Automatic decoding function. This is the useful tools for the signal testing and radio maintenance. 3、The frequency counter can continually test the analog radio signal (handhold radio, wireless phone, etc) and digital radio signal. 4、Simple operation, one key mode. This is a great tool for detirmining what tone frequency a radio system is using. 5、The Three-stage elongated gain antenna can gain the decoding precision and gain the distance. <br> Description: <br> In the walkie-talkie we use in our daily life, usually they will be aging. When we need to buy the walkie-talkie again, and need to go with the old walkie-talkie, so we're going to use this. We can put the frequency meter next to the walkie-talkie, and the frequency and subtone in the walkie-talkie will be automatically scanned by pressing the launch button. Then we can easily connect the data to the newly purchased walkie-talkie and test it out no matter what model. <br> Features: <br> 1.
