Описание The new Baofeng DR-1801 digital radio model is compatible with both Tier 2 repeaters and standard analog repeaters and radios. It differs from the classic Baofeng DM-5R Tier 2 model with a large display, new polycarbonate housing, IP54 waterproof rating, large keyboard buttons and increased battery capacity of 2200 mAh. In addition to the standard analog modulation mode, it supports digital radio communication standard - modulation in DMR mode! Without going into the details of DMR technology, this means that now the sound has become absolutely clear at any distance where the signal passes, i.e. without hiss characteristic of analog walkie-talkies. The use of digital technologies for voice transmission makes it possible to reliably reproduce human speech even with a weak radio signal level, which ensures high quality audio transmission throughout the communication coverage area. Group call of interlocutors, individual calls, general call of all subscribers (system-wide call), digital voice encryption AMBE + 2, sending SMS messages and other functions are available. The radio can also work with Motorola digital DMR radios, which will be an important argument for many. In addition, the radio can work with digital repeaters (DMR Tier 2 standard). The ETSI DMR Tier 2 standard is aimed at users who need efficient use of radio frequencies, advanced voice capabilities and integrated data services in licensed frequency bands for powerful communications systems. The ETSI DMR Tier II standard describes a 2-slot TDMA mode on a single 12.5 kHz wide radio channel. Products of this standard have already been commercialized. The Baofeng DR-1801 radio can also use one time slot and only transmit 50% of the time compared to a conventional analog radio, which saves about 40% battery capacity and extends battery life. The radio has increased the battery capacity to 2200 mAh, which allows the radio to work up to 15.5 hours for transmission and up to 33 hours in standby mode, which is 66% more than its competitors. The new A6 chip provides excellent noise reduction, optimal sound quality with varying conditions reception and low battery consumption. Thanks to the new power amplification chip, the sound on the walkie-talkie is clear and without distortion. Traditionally, like all walkie-talkies, Baofeng supports functions such as VOX voice activation, CTCS and DCS signal coding, frequency scanning, channel and frequency modes. Specifications and functions: Receiving and transmitting frequency: 136-174 MHz / 400-470 MHz; Modes modulations: FM (analog), DMR (digital); Ability to work with Motorolla walkie-talkies and some other DMR digital walkie-talkies; Ability to work with digital repeaters (DMS Tier 2 standard); Group call of interlocutors, individual call, general call of all subscribers, sending SMS messages;Digital voice encryption AMBE+2;Li-Ion battery 2200 mAh,
