The G90 is the first model of the new Xiegu G-series. It's a portable 20W HF 10-160 mtr. multimode transceiver. The G90 uses 24-bit digital architecture. It also includes an internal automatic antenna tuner. The G90 has excellent transmit and receive performance. It packs huge performance into a small portable package.
The G90 has a removable display head that can be separated from the main body and connected via a DB-9 cable (provided with the radio). Both the radio's control head firmware and main body operating firmware can be user-updated using separate connectors on the head and body. The programming cable is provided.
FW Update Note
Please update the display unit first then the base. Also please note you must choose the 1k option in the file transfer menu. In the beginning, you have to press the space bar very quickly or it won't go into program mode.
Detachable Display Unit
The detachable display design allows you to customize your installation.
Color LCD Display Shows
±24khz bandwidth spectrum and waterfall. The sweep/refresh rate is very fast. The status of all functions are shown on the LCD display.
Convenient Side Interface
The G90 uses a standard 3.5mm stereo jack (3-pin) for connecting headphones. Also on the control head is a Firmware update port.
Multi-Function Mic
The microphone has two configurable and several dedicated function buttons.
Features
- Up to 20W of RF power
- High-performance RF front end giving superb selectivity
- Modes provided are USB/LSB/CW/CWR/AM/NFM
- 1.8-inch high brightness color TFT LCD screen
- ±24k bandwidth fast-scan spectrum display with waterfall
- Adjustable DSP band filters (CW mode can be as narrow as 50Hz)
- Detachable front panel/display head unit
- Built-in CW Decoder
- Built-in Antenna SWR scanner
- Built-in wide-range automatic antenna tuner
- Built-in mediumwave (AM broadcast) high-pass filter
- I/Q output for interfacing with a PC or adapter
NOTE
- FM mode is available.
- It's normal that G90 overheats if used for a long time.
- If you want to keep the power of G90 on 20W, the voltage must be in 13.8 V-15V.
If the voltage is 13.8V below, the power would not be guaranteed and the driving kinetic energy would not enough.
