  • Introduction

What's the difference of GP-6688UV with normal dual band two way radio?

 

1. Dual Receive

GP-6688UV 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. GP-6688UV 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:

GP-6688UV radio A: TX/RX 162.2375MHz,

GP-6688UV radio B: TX/RX 426.2375MHz,

GP-6688UV radio C: Dual Standby 426.2375MHz, 162.2375MHz,

Radio C can receive voice of Radio A & B at the same time.


2. 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.


3. 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 165.2375, 415.2375. It indicates the repeater only can receive 165.2375, transmit 415.2375. Two way(double) means the repeater's receive and transmit frequencies are random. The radio will show 165.2375, 415.2375. It indicates the repeater not only can receive 165.2375, transmit 415.2375, but also can receive 415.2375, transmit 165.2375.


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)GP-6688UV radio A: RX 426.2375MHz, Offset: - 264.000MHz

GP-6688UV radio B: RX 426.2375MHz, Offset: - 264.000MHz

GP-6688UV 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)GP-6688UV radio A: RX&TX 162.2375MHz

GP-6688UV radio B: RX&TX 426.2375MHz,

GP-6688UV radio C: Two-way Repeater 162.2375MHz, Offset: + 264.000MHz

Radio A could communicate with Radio B

 

 

4. 360 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.
