dxlAPRS_Scanner

dxlAPRS_scanner - dxlAPRS extension for scanning frequencies

This project contains scanner written in c++ to scan and decode multiple frequencies in the same time.

I would be very happy about ideas and further developments!

You can find scripts to start dxlAPRS and the scanner here. https://github.com/DO2JMG/dxlAPRS_Scripte

Example :

Example frequency list created by the scanner

Unpack and compile :

  git clone https://github.com/DO2JMG/dxlAPRS_Scanner.git
  cd dxlAPRS_Scanner
  mkdir build
  cd build
  cmake ..
  make

Run example :

  ./scanner -p 18051 -u 17051 -f 404000000 -s 1500 -v -o sdrcfg-rtl0.txt -b blacklist.txt -w whitelist.txt -q 55 -n 5 &

Stop :

  killall scanner

Changing parameters for sdrtst :

Adding the following command line argument will enable to send Level table. Replace IP and port with your data, in the example they are just placeholders

  -L <ip>:<port>

Changing parameters for sondeudp :

Adding the following command line argument will enable to send decoded data. Replace IP and port with your data, in the example they are just placeholders

  -M <ip>:<port>

Changing parameters for sdrcfg-rtl0.txt (Frequencies list):

Adding the following line to your channel-file

  s 404.000 406.000 1500 6 3000

Blacklist example :

Add frequencies in kilohertz to the list. Frequencies are separated by a new line.

  405320
  404230

Whitelist example :

Add frequencies in kilohertz,bandwidth khz and afc to the list. Frequencies are separated by a new line.

  405700,6,5
  403000,18,8
  401100,6,5
