5W. It's one of the full band settings of G90.

Yes, all the XIEGU USB-TTL cables are universal.

When using the remote head, please make sure you are using a high-quality DB9 extension cable. As long as the voltage drop on the cable is small enough, the remote head can work normally. The longest length recommended is about 6 meters (18 feet).

No, the headphone port can only drive headphones, not passive speakers.

The G90 output is a mono signal, and the left and right channel are combined on the earphone socket. With a 3.5mm stereo earphone, you can hear sounds on both sides.
If you use a 4-pin earphone, please make sure that the pin definition meets the requirements, otherwise, there may be no sound, low volume, or other errors.

Yes. You can make a cable by yourself. A pinout and interface definition is included in the G90 User Manual

The tuner can match an antenna with an SWR of up to 5:1

No, a balun is needed. Otherwise, the tuning range will be reduced.

Reception is supported from 500KHz to 30Mhz. Transmission is supported on the 10 amateur bands in this range. (160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m)

Yes, it does.

Yes, it can.

No.

When the G90 is transmitting, the ALC (Automatic Level Control) meter will be displayed in the upper right corner of the spectrum display area. The normal reading should be greater than 30, and manual intervention is not needed. If the reading is too low when using the line input, please increase the input volume appropriately.

Yes, both the center frequency and bandwidth of the digital filter can be adjusted.

±1.5ppm. You can fine tune the current frequency deviation based on a reference signal. After adjustment, the frequency accuracy could be ± 0.5ppm.

Yes, please turn on SPL (Split Mode).

No, this interface is not suitable for a serial port and this could cause damage to the interface.

In CW receiving mode, this indicator light will blink in sync with the incoming CW signal when you have the signal tuned to the correct pitch.

No. The buttons below the screen may be dimly lit by light leaking from the display.

No. You can use only one input source at a time.

No.

Yes, and the standing wave protection threshold is adjustable.

The G90's PTT pin is triggered by connecting the pin to ground. This is sometimes referred to as a "Low Level Trigger"

Yes, there is a PTT terminal at the rear ACC port. This control terminal is a bidirectional control port.

No. To control the transmission of the G90 from outside, you need utilize the provided PTT pin on the rear ACC interface. The CIV command can also control the PTT state of the device.

The AGC function needs to be turned on for the S meter to be displayed.

The level reading error of the S meter is ± 2dB, which is significantly more accurate than a standard pointer meter.

No.

± 24k bandwidth centered on the current signal.

The SCAL reference level value needs to be adjusted.

≥50dB.

The accuracy of the built-in SWR scanner is sufficient for antenna debugging, and can accurately reflect the SWR of the current antenna feeder system. The scanning power is generally around 5W, which is more accurate than most cheap meters. More precise measurement requires professional instruments.

Yes, it can be turned off in the radio settings menu.

Yes, press the CMP button to enable voice compression.

Yes, FUNC + press the volume knob to set accordingly.

When AGC is turned off, the G90 is in the highest gain state, and the noise will be significantly increased. It sounds loud, but it may reduce the signal-to-noise ratio and dynamics. It is recommended to turn on AGC.

Yes, and the auto key rate can be adjusted.

To decode a CW signal requires:
1. The frequency is tuned to the correct pitch.
2. The received signal-to-noise ratio(SNR) is strong enough.
3. The code sent by the other party should be standard. If the code is sent manually, the decoding accuracy is lower. If the code is sent from a computer or by a machine automatically, the decoding accuracy is higher. Generally, automatic decoding is only a supplement to manual copying.

Yes, it can be used for IAMBIC A/B Mode switching.

Yes, it can.

No, it can't.

Yes.

No, you need to turn the mode to CW or CWR.

Yes, it does.

Compared to CW, it a sideband report mode. In some cases, CWR mode can be used to eliminate some specific interference nearby.

No, it doesn't.

Yes, please see the user manual for full details of the included noise blanker.

SSB/CW/AM.

No.

Yes, it can.

Yes, there is an audio input/output terminal at the rear ACC port, which is specially used for external input /output.

Yes, you can control it with software like HRD, HDSDR, etc.

Standard CIV protocol, compatible with ICOM.

Turn off the G90, hold the FUNC button, and turn on the machine, then your radio will be reset. (this reset function was added in firmware version V1.73)

When updating the firmware, the head and body need to be updated at the same
time, and the firmware version number must be the same for both. For detailed
operation, please refer to the Firmware Upgrade Instructions:

How to update Xiegu G90 firmware?

Repeat the update procedure. The device will not be bricked.

Item #7 in the radio menu shows the firmware version

The hardware in the G90 and G90S is identical. The G90S is the original model for the Chinese market, with the G90 being the model for sales overseas. The G90 is provided with a different set of operating frequencies based on the sales region.

100

On the left side of the radio head unit (below the headphone port).

Yes, its CMIIT ID is 2019FP3960.

The G90 uses a Mixer SDR with a 24 bit @ 48khz DAC

EL-2P

10.5~16.5V

10A fuse

Can the G90 be powered with 4 Lithium batteries which are 16.8V in total?

There is a ground terminal connection at the rear panel, which is for the ground wire connection. Good grounding can help improve the performance of the equipment and enhance its anti-interference ability.

The maximum emission current could be up to 5.5A, when under 13.8V DC power, and the emission current in full power transmitting can't be higher than 5.3A. A power supply with 6A or above output power would be recommended.

The G90 can transmit at full power with input voltages at or above 11.5V. Input voltages above 13.8V will not improve the output power, as the APC unit in the radio will regulate the power automatically.

Select CW mode, press the key to start transmission, and observe the output power reading displayed on the screen.
You can also use an external power meter to help. Do not use SSB mode to check as it will be affected by the input volume, which may cause a large change in output power.

The reverse polarity protection consists of a fuse in the power cord and an internal circuit. When the radio is accidentally miswired, the fuse will blow, and the internal protection circuit will take action to prevent further damage. To repair it, you just need to just replace the fuse and repair the protection unit inside the radio. Generally, it will not cause more serious damage.

0.25uV @ 10dB S/N

Yes, you can connect the I/Q signal to your PC's sound card, and use appropriate SDR software to see a spectrum.

Yes, it provides both a spectrum and waterfall display.

Yes. There's a standing wave meter on the right side of the screen, and the current standing wave ratio will be displayed when transmitting.

Yes, continuously adjustable from 1 ~ 20W in steps of 1W.
