Overview TRU35 is a high-power, small-size half-duplex digital radio designed by using advanced 32-bit cortex M4 microcontroller technology, wireless transceiver RF technology, and digital communication technology, this radio selects high-quality RF components, excellent EMC and EMI processing, and shell & heat sink integration technology. It has the advantages of high transmission power, long transmission distance, integrated transmission and receiving, simple installation and use, high cost performance, stable and reliable. II. Functions  Receiving and transmitting are integrated in one, half duplex, fast switching  Radio relay function greatly improves the transmission distance TRU35 can send the received data through other frequency points, increasing the communication distance and expanding the signal coverage.  Level 2 surge protection, reverse polarity protection The TRU35 adopts a level 2 surge protection to protect the radio from damage when the instantaneous input voltage or current exceeds the normal range. Even if the positive and negative polars are connected inversely, the radio will not be damaged.  Standing wave detection protection TRU35 adopts standing wave detection protection to prevent damage to the instrument caused by long open and short circuits.  Thermal protection TRU35 can adjust the transmitting power adaptively, automatically reduce the power when the instrument temperature is too high, and automatically increase the power when the instrument temperature decreases, to ensure that the instrument is always in a stable power range, and will not be damaged due to overheating.  Protection- IP67  Without assembly, integrated shell, high overall heat conduction efficiency and good heat dissipation 2  Bluetooth configuration and Bluetooth datalink functionality TRU35 can configure and set its mode, protocol, air interface baud rate, frequency, high or low power through handheld via Bluetooth connection. It can also receive RTK data through Bluetooth and send it out through radio.  Standard 16 channels for transmitting and receiving, users can configure and use according to the situation  Under the condition of high transmission power, the transmission distance can reach 14 kilometers (depend on the base station height and the surrounding environment) III. Main Technical Indicators 3.1 General Indicators Frequency range: 410MHz-470MHz Operating mode: half-duplex Channel spacing: 25KHz Frequency stability: ≤±1.0ppm Modulation method: GMSK/4FSK Air transmission rate: 9600bps, 19200bps Antenna interface impedance: 50ohm Rated working voltage: 12.5V (working voltage range: 10.8V-15V） Weight: 1680g Volume: 165mm×125mm×80mm 3.2 Receiving Indicators Sensitivity: better than -116dBm@BER 10-5,9600bps Common channe…

The lower limit shall apply at the transition frequencies. 10.3.Test Procedure (1) The EUT was placed on a non-metallic table, 80cm above the ground plane. (2) Setup the EUT and simulator as shown in 10.1 (3) The EUT Power connected to the power mains through a power adapter and a line impedance stabilization network (L.I.S.N1). The other peripheral devices power cord connected to the power mains through a line impedance stabilization network (L.I.S.N2), this provided a 50-ohm coupling impedance for the EUT (Please refer to the block diagram of the test setup and photographs). Both sides of power line were checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipments and all of the interface cables were changed according to ANSI C63.10:2013on conducted Emission test. (4) The bandwidth of test receiver is set at 10KHz. (5) The frequency range from 150 KHz to 30MHz is checked. 10.4.Test Result PASS.
