Dual Receiving

One of the most prominent features of RT23 over other radios is Dual Receiving.

Many dual-band radios can listen to two channels and monitor two different frequencies.

But at the same moment, it can only accept one signal of one of the two bands. If A band has a signal, it will receive A and it cannot accept the signal of the other band B unless the current A’s signal ends.

RT23 not only can monitor both frequencies but also can receive two incoming signals at the same time.

What’s more, you can set the volume mode ( menu 35).

MAIN indicates the main frequency sound is louder when receiving, SUB is indicated the sub frequency sound is louder when receiving. OFF indicates both main and sub frequency have the same sound.

Dual PTT

You can set a Sub-PTT by side key. If so you don’t need to choose the transmit channel. Push PTT transmit the main-channel, push another side key will transmit the sub-channel. Very convenient.

Receive signal when using FM radio function

There are lots of radios have FM function.

In order to receive any calls, most of the radios’ default settings are automatically receiving the signals when we listen to FM radio.

Some people think it is very good, but some other people think it is a little problem. Because during this time they don’t want to be disturb.

Retevis RT23 will give you more choices. The calls were received when you listen to FM is up to you.

Turn on the DW function, Receive two-way radio Signal when listening to FM radio, Never miss the important information.
