Guohe Q900 HF/VHF/UHF All Mode SDR Transceiver

$619.00

Q900 is an ultra-portable full frequency full mode SDR radio launched by us. The receiving frequency is 300kHz ~ 1.6GHz, and the amateur transmitting band covers 160m ~ 70cm. Q900 is designed with three power supply modes, including a built-in battery, USB port power supply and DC port power supply. The power supply voltage range is 5VDC ~ 32VDC. At the same time, all power ports support anti-reverse connection protection.

Description

Q900P is an ultra-portable all-modes all-bands radio based on the software-defined radio (SDR) technology. The frequency covers all amateur bands from 1.8 MHz – 470 MHz. Q900 operation modes include FT8, SSB, CW, AM, FM, RTTY and DMR. It includes all the advanced functions and features of all radio stations.  Built-in Bluetooth, can be directly connected to mobile phones, computers, and Bluetooth microphones. 

Standard FM module, Bluetooth module, Bluetooth microphone Built-in, sound card Built-in, automatic tuning Built-in memory, Optional GPS module, LORA module, electronic compass module, wired microphone.

Q900 is an ultra-portable full-frequency full-mode SDR radio. HAM-BOX is an independently developed App for a smartphone that permits remote control of the Q900 transceiver.

The HAM-BOX mobile app we developed allows the mobile phone to easily control and play radio stations, it makes the operation of the radio more convenient and fast, the radio adopts a full keyboard design, built-in Bluetooth module, Sound card module and communication serial module. Full support for currently popular radio control software and logging software, We are working hard to give you more playable space. Note: Specifications are subject to change without notice or obligation. 

The Q900 has many advanced functions that are only available in a large base station. The machine has dual VFO mode, different frequency working function, IF offset adjustment, receiving frequency fine adjustment, IF noise suppression, AGC speed selection, RF gain adjustment, squelch control, pre attenuator, AM broadcast reception, built-in telegraph automatic key, automatic key point ratio adjustment, built-in CTCSS analogue sub tone, automatic shutdown function (APO), transmission timeout function (TOT), connection with a computer, computer-aided control function, copy function, etc.
