The second func�on (with the FUNC bu�on ac�vated) of the [LOCK] bu�on is
as follows:
SCALE: set the reference level se�ng
AVE: set the average value se�ng
AVE "average" values gradually increase from 1 to 10. The effect on the display
is to smooth out rapid changes and provide a be�er representa�on of band
ac�vity. This se�ng is a ma�er of personal taste. It can improve usability of the
spectrum display.
Data Communica�on
The G90/S supports all PC-generated amateur data communica�on modes and
remote control via computer so�ware when a PC is linked to the radio. Only
simple wiring is needed to enable amateur data communica�ons.
The appropriate transmission mode should be selected for the data mode in
opera�on. The recommended modes for common data modes are as follows:
Data mode
PSK31
RTTY
FT8
When an amateur radio and a computer communicate using digital data
communica�on, the computer is used as a "modem" in that it converts the
signals to and from digital tones. While receiving, the audio from the signal
received is sent to the computer for demodula�on. When transmi�ng, the
audio signal created by the computer is sent to the radio for transmission.
Thus, the computer's audio output level effects the TX power output and ALC
readings. The connec�ons required are as follows:
Receiving: Received audio from the receiver→ computer audio IN
Transmi�ng: The computer-generated audio signal → radio TX Audio IN
Prepara�on:
For CAT command control of the radio from the PC we use the supplied
USB->3.5mm plug cable. Before the first �me you use the cable, download
and install the cable driver from the Radioddity website. Now when the
cable isplugged it, it will use this driver and not go off to search for an
(incompa�ble) one from the Web.
