Radtel RT-820W Dual-Band Two-Way Radio （VHF 20W/UHF 18W) Professional Dual-Band Radio with Advanced Signaling & Fast Team Setup The Radtel RT-820W is a versatile dual-band handheld two-way radio designed for users who need flexible communication, extensive channel management, and advanced signaling features. With support for VHF 136–174 MHz and UHF 400–470 MHz, up to 500 channels, a large function keypad, 360° encoder, dual PTT buttons, and a range of analog and digital features, the RT-820W is suitable for amateur radio, outdoor activities, team communication, and professional applications where permitted by local regulations. Key Features 📡 Dual-Band VHF & UHF Supports: VHF: 136–174 MHz UHF: 400–470 MHz Same-frequency simplex and different-frequency simplex operation Convenient UV band switching 💾 500 Channel Capacity Store up to 500 channels with frequency and related channel information, making it easier to organize different communication groups and operating frequencies. 🔎 Built-In Frequency Measurement The RT-820W includes a frequency measurement and decoding function. When another radio is transmitting, the RT-820W can measure the frequency and store the result into a channel, making it easier to quickly set up communication with compatible radios. 👥 Quick Team Formation The Quick Team function allows multiple compatible radios to quickly synchronize to a common channel. One radio can act as the transmitter while other radios enter Quick Team Reception mode. After synchronization, members of the same group can communicate with each other. 🔐 Digital Communication Features The RT-820W supports digital service functions including: Radio alias/name display Caller name display Local group communication Digital voice password Digital anti-cracking function The digital voice password can be configured from 0001–8999, and compatible radios must use the same password for communication. The digital anti-cracking function supports numerical coding from 1–49999. 🎙️ CTCSS / DCS Choose from 50 CTCSS tones and 105 DCS codes for selective communication and reduced unwanted traffic from other users sharing the same frequency. 📞 DTMF Signaling The RT-820W supports DTMF signaling with 16 codes, including encoding, decoding, and dialing list configuration for selective calling applications. 🚨 2-Tone & 5-Tone Signaling 2-tone and 5-tone signaling can be used for selective calling and triggering specific operations. The function is suitable for applications such as alarms, scheduling, coordination, and emergency communication. 🎛️ Flexible Controls The radio features: 360° rotary encoder Numeric keypad LCD display Dual PTT buttons Programmable side buttons Emergency alarm button Strobe light External microphone/headset connection The side buttons can be configured for different functions using short-press and long-press settings. 🔊 Wide Range of Channel Settings The display provides information for channel parameters including: High / Low power Wide / Narrow bandwidth CTCSS / DCS VOX Frequency shift Reverse frequency Other system parameters Technical Specifications Feature RT-820W Frequency Range VHF 136–174 MHz / UHF 400–470 MHz Channels 500 Operating Voltage DC 7.4V / 12.6V Lithium Battery Operating Temperature -20°C to +50°C Operating Mode Same-frequency simplex / different-frequency simplex Modulation F3E CTCSS 50 tones DCS 105 codes DTMF 16 codes Frequency Measurement Yes Quick Team Formation Yes 2-Tone / 5-Tone Yes Digital Services Yes Digital Anti-Cracking Yes VOX Supported Wide/Narrow Bandwidth Supported The specifications above are based on the RT-820W instruction manual.
