    A "1750Hz two-way radio" is
    a two-way radio with a specific feature for activating repeaters, which is a signal to open a repeater for communication. This is a common feature in many European ham radios, where the 1750 Hz tone burst is a standard way to access repeaters, though it is not commonly used in the United States, which typically relies on CTCSS/PL or DCS tones. 
    1750Hz tone burst 
    • What it is: A tone burst is a short, high-frequency tone sent at the beginning of a transmission.
    • How it works: By sending a 1750 Hz tone, the user "opens" the repeater, allowing them to then transmit their message.
    • Purpose: It's an activation command that allows a short-range radio to communicate over a longer distance by using a repeater as a relay.
    • Activation: The tone is often activated by pressing a button, such as the squelch open button. 
    Use in two-way radios 
    • Frequency: Many two-way radio models, particularly those designed for the European market or international use, include the 1750 Hz tone burst feature.
    • Examples: Models from brands like Baofeng, TYT, and Retevis may have this functionality, as seen in listings on sites like AliExpress and Alibaba.com.

    What is the best frequency for two-way radios?
    VHF and UHF Radios Compared - Which Is Best? VHF (136 - 174MHz) signals generally work best outdoors, giving a somewhat longer range for the same power output than UHF (400 - 470MHz). However, VHF signals really do not work well when there are obstructions like buildings around.
