Xiegu G90 FAQ from Radioddity
Answer
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.
(Any speakers connected must be active powered 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. (The hardware does not support this frequency range.)
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.
