Connect the USB cable to G59 USB port. Plug the other
end to any available USB port in your PC.
Connect 12V DC power supply.
Upon the power up, your PC will automatically recognize
G59 hardware. Once the USB connection is established
the green LED diode will light.
Download and install Power SDR (tm) Genesis
During installation select G59 as your hardware. If you
have previously used GSDR software with other Genesis
hardware then go to Power SDR settings - General -
Hardware Config - Radio Model - select Genesis G59.
The GSDR will automatically detect your G59 hardware
and will establish USB connection. The USB button will
light up green.
Checking the G59 and GSDR communication
Press the AF Preamp button.
AF preamp "on", the voltage between pins SV1PA is
(with AF preamp "off" the voltage is 0V).
on "Tun" button.
voltage between pins of SV2PA should be around
Band selection check
Connect the input of frequency counter to resistor
60m band, LOSC frequency 5.330MHz.
frequency counter should read 5.330MHz.
Now select other bands as well. Again, the frequency
counter should show the frequency exact or very close
to LO frequency for selected band.
completes testing of connectivity between G59 and GSDR
Communication between Genesis software and
hardware is very much a straight forward procedure
where default settings are loaded upon startup of GSDR.
In case of no USB communication check the following:
- make sure to select G59 under Hardware
under General - Genesis Config tab select Si570 address
Windows unable to detect G59
Symptom: green LED off, no USB connection.
There are a few possible reasons why Windows is unable
to detect G59 hardware. Some of them are:
- USB cable not connected properly
- device not recognized by OS
- G59 micro controller not installed properly
- micro controller firmware not loaded properly
- G59 hardware assembly problem
The troubleshooting procedure is to determine which of
above listed problems is causing lack of
check USB connectivity download and run Windows
USB Viewer [usbview.exe].
Windows is unable to detect or recognize G59 hardware,
"NoDeviceConnected" status will show under the
list of USB devices.
Properly detected and recognized G59 hardware
will show up under USB view as

Si570 "locked" on 56.320 MHz / 14.080 Mhz
Symptom: green LED on, USB connection present. However, regardless of which band is selected, under GSDR the Si570 appears to be "locked" on 56.320 MHz / 14.080 MHz.
Most likely, lack of communication between microprocessor and Si570 is caused by either missing / corrupt firmware or malfunctioning / incorrectly installed MOSFET TR1G and TR2G.
