The frequency meter capable of measuring the parameters of the frequency of the continuous carrier signal walkie-talkies , with signal strength indicator.
This portable frequency counter is designed for counting continuous wave signal comes from Two-way Radio.
There are easy ranges for you to choose. The ranges cover most of the frequency of the two way radios you want to measure.
Its four-button control is easy to use and its small size allows you to carry it anywhere you like.
Work by TCXO(Temperature Compensate X'tal (crystal) Oscillator) ,In the range of -45 ℃ ~ 65 ℃ can reach ± 2 ~ ± 4ppm accuracy
This include very interesting frequency areas such as 2m HAM radio, all VHF and UHF
