필요시 정보를 관련공항에 접근하는 항공기에게

당해 주파수를 이용 방송하는 시스템임.

5. GND = 공항에 항공기가 지상에서 이동하거나 주기장에

정지 L/B (탑승구) 에 접근하는등 지상에서의

행위를 할경우 사용하며 작은 공항(?)에서는

니 주파수를 별도로 두는것이 아니라 TWR 주파수

하나 정도로 복합 운용함

6. DLVRY = 국제공항급에서는 항공기의 이륙허가(승인)용으로

별도 운영함.

7. EMG = 이것은 여러분이 잘 알고있는 비상주파수임

특히 주의하셔야함

그리고 비상시 뿐만아니라 상호 주파수를 모를경우

이 주파수를 이용하여 의사소통을 함

8. DEP = 이것은 국제공항급에서 출항하는 항공기의 관제용

으로 다음의 관제구역 까지의 항공기 유도에 사용됨

9. A/G = 이 주파수는 항공교통 써비스 주파수로 항공기 교통

관제를 제외한 업무연락용으로 현재는 항공사가

자체의 통신망 혹은 공항통신써비스

(AOC=항공기 운영사를위한 공중통신)을이용하고있슴

10. VFR. IFR = 시계비행 . 계기비행

11. ASR = 공항 감시레이다 ( 공항부근을 감시하는 레이다)

보통의 레이다 보다 컴퓨터 부분이 보강된 항공기의

속도, 고도, 편명(인식)등을 자동인식하며 근래에는

SSR (2차 감시레이다)과 연계하여 그 위력을

발휘하고 있슴.

12. PAR = GCA 절차에 필요한 정밀 접근 레이다을 말하며

현재는 ILS 향후는 MLS(MicrowaveLandingSystem)

혹은 DGPS(GPS와 유사하나더 정밀함)로 교체중임

MFJ-1026 Noise canceller Modification Plan

After some research on the Internet. I concluded this.

MFJ-1026 Noise Canceller modification Plan

1. Reduce Low frequency attenuation (increase gain at 1.8 MHz) 

 - Change C8, C16 (680pF) with 1.6nF   for Better high pass filtering  

 - Change  C18 (680pF) with 1.6nF  for better pass through 

 - May Change L3, L4, L5, L6 (5.6 uH) with 10 uH  ==> No need to change (Just Increase Cap to decrease attenuation at 1.8 Mhz)

2. Better IM Dynamic range

 - Remove Diodes D6, D9, D10, D11

3. Better Gain

 - Add 4:1 transformer to the output of  Q4 (C1)

4. Better control of Phase range (Swap inputs)

 - ADD DPDT SW & Coax to swap  the inputs of  Q8 and Q5

 -  Q8  ->   SW  ->  R20;  Q5  ->  SW  -> R9

5. Getting Better phase range and control

 - Change C13 (120pF) with (47pF  => 68pF)  - Increased range for high band position

 - Change C12 (470pF) with 680pF   - Better phase control for low band position

6. Protect Aux Antenna FET from high power operation

 - Install an AUX antenna input grounding Relay. 

 - Connect Relay (+) to (C2-Q1 junction pad) and  Relay (-) to  (R5-Q2 junction pad), -Install a diode

 - Install a protection diode

 - Need a 12V relay for isolation and a Diode for protection (NA1S TQ2-12V, Single side stable)

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
