Application of frequency scanning in SHTF

Frequency scanning makes it easier for the prepper to contact others in an emergency. Get help in the shortest possible time.

What is frequency scan?

In frequency scanning mode, Two-way Radio will move from the start frequency to the stop frequency at the specified scanning rate, testing whether there is a signal at each frequency point. When a signal is detected, the frequency point currently being communicated can be determined.

Why Prepper requires frequency scan

Two-way Radio requires the same frequency and sub-audio frequency to communicate. But during emergency communication, we don’t know the other party’s channel frequency and sub-audio frequency. Don’t even know if anyone is nearby to communicate. Through regular Two-way Radio frequency scan, communication signals can be discovered instantly. and communicate with it.

RA89 supports frequency scanning and sub-audio scanning

While RA89 detects frequency points, it can also detect sub-audio frequencies. After obtaining the frequency point and sub-audio frequency, you can communicate with the channel.

  1. In VFO mode, long press the A/B key to enter seek.
  2. The air signal is searched, and the screen displays the frequency and sub-audio frequency.

You can now communicate with the other party. It can also be saved to the channel.
