How does the children’s walkie-talkie communicate with analog radio? Can children’s walkie-talkies and analog radios communicate with each other? Recently, we received this question: “Retevis RT36 in Europe compatible with other PMR446 models like Retevis RT618? Today, I got RT36, and I got very strange behavior. Between two RT618, they work well. And between two RT36, they work well, too. However, between RT618 and RT36, they don’t work. Here’s the detailed behavior: All four devices (two RT36 and two RT618) are on. All of them are set to channel 1. – When the PTT button is pressed at an RT618, I can see the RX icon in the RT36’s screen. But no sound is coming through RT36 while another RT618…

How the Retevis RT3 communicate with H777 1. What requirement should must meet if two radio want to communicate? 1).They all by Analog radio or Digital radio 2).They can set up same frequency/Channel (They have the same frequency range.) 3).They can set up same CTCSS/DCS.   2. How to set up the RT3 communicate with H777. Retevis RT3 is one digital radio, but it has both Digital and Analog mode. H777 just Possess the Analog mode.   Step 1: Choose the RT3 Channel mode by “Analog” at Software. Step2: Choose the RT3 and H777 common frequency range to confirm they can set up same frequency. Step3: Set up the same frequency/Channel at the RT3 and H777 software: Step4: Set up…

How the RT40 to communicate with retevis other radio 1.RT40 Frequency/Channel is fixed, can’t modify, so just to set up the CTCSS/DCS, Color code and other function. 2.At the Analog mode, just set up the others radio’s frequency/Channel and CTCSS/DCS same as RT40 is ok. 3.At the Digital mode, need other radio also is Digital mode, and set up the same colour coder(AMBE+++), also ensure others frequency should same as RT40. 4.Set up the name of contact people and add them to the corresponding channel.   For example: How the RT40 communicate with retevis RT82 Step 1: RT82 working frequency: 136-174Mhz, Support the DMR Tier I, colour coder(AMBE+++), ID No.: 1234 Step 2: RT40 working frequency: FIXED, Support the DMR…
