G90S 20W Amateur Shortwave Radio for XIEGU H-structure Portable SDR Transceiver with Heat Dissipation Function

Improvements:
- The main body structure of the aircraft has been changed to H-shaped.
- The material of the power cord is thickened.
- Add a heat dissipation duct at the bottom and rear of the machine.
- Optimized the speaker structure.
- Add a speaker switching switch.
- Optimizing the circuit has improved the signal-to-noise ratio.
- Change the power plug for Anderson.

Description:
- The G90S is an amateur radio short-wave transceiver with a portable 20W in the SDR architecture.
- Based on 24bit-C0DEC sampling, the G90S brings superior transceiver performance and a highly configurable feature experience; the separate head design allows you to flexibly position your host; with built-in high-performance ATU, you can meet your needs at any time. From then on, the antenna erection and adjustment are no longer problems.
- G90S has a built-in variable bandwidth digital filter, which can continuously adjust the filter bandwidth to improve the immunity and selectivity of the walkie-talkie.
- The G90S walkie-talkie can display the spectrum and waterfall chart of the received signal, and can quickly observe whether there is a communication signal on the adjacent frequency, which is convenient for users to quickly track and switch frequencies, and quickly follow the channel.
- It has a wealth of expansion interfaces, KEY interface can be used to connect CW keys, COMM interface is used for firmware update and upgrade, I/Q signal interface is convenient to connect XDT1 and computer SDR spectrum adapter, ACC interface can be used for data communication with CE19 adapter card Transmit audio signal or connect XPA125B amplifier.
