sm3ulc/wspr-scripts

This repo is for various scripts for using SDRs to do WSPR.

wspr-scripts

These are scripts for running wspr on rtl-dongles and SDRPlay.

Installation

Basic packages

apt-get install imagemagic sox curl 

##The DSP-parts u ses csdr which be found here

csdr - https://rtgithub.com/simonyiszk/csdr

##For the RTL-SDR dongles:

https://github.com/keenerd/rtl-sdr

##For the SDRPlay

https://github.com/krippendorf/SDRPlayPorts

##WSPR-decoder

Install latest WSJT and check that wsprd is reachable rom the shell.

https://sourceforge.net/projects/wsjt/files/

A minimal installation can be made by downloading and unpacking of the sourcecode and just compiling the decoder itself:

   wget "https://sourceforge.net/projects/wsjt/files/wsjtx-1.6.0/wsjtx-1.6.0.tgz/download"
   tar -xvf wsjtx-1.6.0.tgz
   cd wsjtx-1.6.0-rc1/src/wsjtx/lib/wsprd
   make
   sudo cp wsprd /usr/local/bin

Finally. Download scriptfiles and change call and grid and working/data directories! For troubleshooting/calibration there's output to different spectrograms which preferably can be viewed via the included webpages.

Usage

Crontab:

*/2 * * * /wsprdir/script.sh

To redirect all output including stderr to a logfile and add timestamps

script.sh 2>&1 | ts "%Y-%m-%d %H:%M:%S" >>dir/run.log

Todo

• queuing of uploads for the simes when wsprnet is out of reach

Issues

When running with standard RTL-dongle the frequencydrift is too high if run from within the script. Therefor one has start rtl_tcp separately in order to not let it cool down.
