What makes RT23 unique?
1.Cross-Band Repeater Function.
Turn on the cross-band repeater function(menu 6). You can choose one-way or two way repeater(menu 34). One way(single) means the repeater's receive and transmit frequencies are specific. The radio will show 162R2375,426T2375. It indicates the repeater only can receive 162.2375,transmit 426.2375. Two way(double) means the repeater's receive and transmit frequencies are random. The radio will show 162*2375,426*2375. It indicates the repeater not only can receive 162.2375,transmit 426.2375, but also can receive 426.2375,transmit 162.2375.
Cross-Band Repeater function also can increase the distance of communication. If you choose two way repeater, it canmake the UHF radio communicate with VHF radio. When you turn on the repeater function, you also can set if the radio PTT Transmitting(menu 33) and Speaker(menu 32) is available.
For example:
(1)RT23 radio A: RX 426.2375MHz, Offset: - 264.000MHz
RT23 radio B: RX 426.2375MHz, Offset: - 264.000MHz
RT23 radio C: Repeater RX 162.2375MHz, Offset: + 264.000MHz
Radio A could communicate with Radio B,It also can increase the distance of communication.
(2)RT23 radio A: RX&TX 162.2375MHz
RT23 radio B: RX&TX 426.2375MHz,
RT23 radio C: Two-way Repeater 162.2375MHz, Offset: + 264.000MHz
Radio A could communicate with Radio B
2.Dual Receive
RT23 is not same with other radios. Other radios can "watch" two channels. Mointor two different frequencies(even on different bands (VHF/UHF)) and the radio will monitor both frequencies giving priority to the first station to receive an incoming call.RT23 not only can "watch" both frequencies, but also can receive two incoming calls at the same time. What is more,you can set the volume mode by the menu 35. MAIN indicates the main frequency sound is louder when receiving, SUB is indicates the sub frequency sound is lounder when receiving. OFF indicates both main and sub frequency have same sound.
For example:
RT23 radio A: TX/RX 162.2375MHz,
RT23 radio B: TX/RX 426.2375MHz,
RT23 radio C: Dual Standby 426.2375MHz, 162.2375MHz,
Radio C can receive voice of Radio A&B at the same time.
3.Dual PTT
You can set a Sub-PTT by side key. If so you need not to choose the transmit channel. Push PTT transmit the main-channel, push another side key will transmit the sub-channel. Very convenient.
4.306 Degree Channel Knob
The channel knob can rotate 360 degree. You can operate the menu up and down by this knob. It is very convenient.
