Precision 5820/7820/7920: NVME 드라이브에서 Windows 10 설치가 실패 함

1. Download  RSTe 5.3.1  at 

   https://www.dell.com/support/home/drivers/driversdetails?driverId=TV5DJ

2. Extract the file to   "/Drivers/BootCritical" directory of USB boot media

3. Do 3rd party driver install at Recovery screen, by selection Windows8.1 directory

NOW the Windows recovery recognize NVME SSD at MiniSAS-0 slot.

Using the LG AN-WF100 USB Wi-Fi adapter for PC

 

The LG AN-WF100 USB Wi-Fi dongle left, after trashing the TV.

 This dongle uses a generic Broadcom chipset. To use the dongle at Windows 7 PC

1. Download a compatible driver from http://www.downloads.netgear.com/files/GDC/WNDA3100V2/WNDA3100v2_V2.2.0.5.zip

2. Install the driver normally. Close application

3. Remove/Disable WNDA3100v2.exe from the strat-up entry

4. Now plug-in the LG dongle to your PC. It will be detected as an unknown “Remote Download Wireless Adapter” device.

5. Open Device Manager, right-click the unknown “Remote Download Wireless Adapter” device, select “Update Driver…”, choose to browse for the driver.

6. Select the “Network adapters” category, scroll down to “Netgear”, select “Netgear WNDA3100v2 N600 Wireless Dual Band USB Adapter”.

7. Just Ignore the warning about driver compatibility.

That's it.

Raspberry Pi3B WSJT-X and WSPR install with RTL-SDR

 

O Prepared gears:

 - Raspberry Pi3B with >8GB SDHC

 - Old RTL-SDR dongle 

Setting up

1. Prepare RPi3B

 - Install the latest image from https://www.raspberrypi.org/downloads/raspberry-pi-os/

  sudo raspi-config

  In the localization settings change the timezone to UTC (localization options -> time zones -> none of the above -> UTC

2. Install RTL-SDR drivers

sudo apt-get update
sudo apt-get install libusb-1.0-0-dev git cmake -y
git clone https://github.com/keenerd/rtl-sdr
cd rtl-sdr/
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo cp ../rtl-sdr.rules /etc/udev/rules.d/
sudo ldconfig

echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf

Now reboot to apply the blacklist, and plug in your RTL-SDR.     

3. PulseAudio & MPlayer

Need PulseAudio to create virtual audio cables. Also install mplayer for playing the audio.

sudo apt-get install pulseaudio pavucontrol mplayer -y

4. CSDR

CSDR is a library of DSP functions that we'll use to set up a multi-channel receiver.

sudo apt-get install libfftw3-dev -y

cd ~
git clone https://github.com/simonyiszk/csdr
cd csdr

Before going any further, for the Pi 3 we recommend editing the Makefile and changing the PARAMS_NEON flags to the following. The Makefile can be opened with 

  "sudo leafpad Makefile"

-march=armv8-a
-mtune=cortex-a53
-mfpu=neon-fp-armv8.

Also under PARAMS_RASPI set:

-mcpu=cortex-a53
-mfpu=neon-fp-armv8.

We're not sure if it actually does anything, but the idea is that this should help optimize the code for the Pi 3 CPU. For any other SBC, you'll want to check what these settings should be for your architecture.

Close and save the file, then run:

make
sudo make install

5. ncat 

The ncat is a TCP server that we'll use to help us set up a multi-channel receiver.

sudo apt-get install nmap -y

6. Chrony

We'll use Chrony to adjust the time offset required by these QRP modes. The configuration will be discussed later.

sudo apt-get install chrony -y

7. WSJT-X

Go to the WSJT-X page in Chrome, download the .deb file for the Raspberry Pi, And Install it.

8. Audio Piping Setup

Need to create virtual audio sinks for each frequency that you want to simultaneously monitor. The example below will set up two virtual audio sinks that load on boot. 

To set up another, simply add more lines from Virtual 2 and and so on. First open the pulseaudio default.pa file:

sudo leafpad /etc/pulse/default.pa

Add the following lines to the end of the file:

load-module module-null-sink sink_name=Virtual0 sink_properties=device.description="Virtual0"
load-module module-null-sink sink_name=Virtual1 sink_properties=device.description="Virtual1"

Disabling PulseAudio logging is recommended, as this seems to be a large user of CPU cycles.

sudo leafpad /etc/pulse/daemon.conf

 Find "log-level" and change it to "log-level = error". 

; log-target = auto
log-level = error
; log-meta = no

 Now reload pulseaudio either by rebooting, or running "pulseaudio -k" at a command line.

9. RTL-SDR Setup

Set up an RTL-SDR TCP server with ncat. In this example, the center frequency is set to 14.1 MHz (14100000 Hz). 

Change this to whatever frequency band you want to monitor.   Just remember to offset the center frequency by a few hundred kHz from the actual signal frequency to help avoid the center DC spike.

4. Set-up a GPS dongle and Time Sync

a. Prepare USB connected GPS device

b. Install the following software:

  sudo apt -y install gpsd gpsd-clients python-gps chrony python-gi-cairo

c. Make changes to the gpsd configuration file as follows:

  sudo nano /etc/default/gpsd

d. In the file that opens, add or amend lines to make sure the following is present:

  START_DAEMON=”true”

  USBAUTO=”true”

  DEVICES=”/dev/ttyACM0″

  GPSD_OPTIONS=”-n”

  Hit ctrl-x followed by y to close and save the file.

e. Reboot the Pi and check that the following services are active:

  systemctl is-active gpsd

  systemctl is-active chronyd

f. Use any of the following three commands to check that the GPS is visible and delivering NMEA words. 

  cgps – s   or   

  gpsmon -n  or   

  xgps

g. Next, make a change to the chrony configuration file:

  sudo nano /etc/chrony/chrony.conf

Add the following line to the end of the file:

  refclock SHM 0 offset 0.5 delay 0.2 refid NMEA

  Hit ctrl-x followed by y to close and save the file.

h. Check chrony’s sources with the command:

  chronyc sources -v

 - You will see a list of available time servers plus the GPS source which will be shown as NMEA. Without the network connection, you will just see the NMEA source listed. 

 Symbols in MS "#*"  where # means the GPS is recognized as a local clock, * means that it’s being used to synchronize the Pi system time.

i. use chronyc to provide a more detailed view using the command:

  sudo chronyc tracking
