Installing utility software on a Raspberry Pi

This document will guide you through installing SDR applications on the platform built in the document: Installing drivers and support for the SDRplay RSP1A on a Raspberry Pi and depends on that installation.

Install:

Hamlib (if you want to integrate WSJT-X with your SDR)
The Ham Radio Control Library-Hamlib, for short-is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users.
- Download the hamlib-4.1.tar.gz archive from https://github.com/Hamlib/Hamlib/releases to a directory such as your home directory.
```
cd ~/
tar -zxvf hamlib-4.1.tar.gz
cd hamlib-4.1
./configure
make -j 4
sudo make install
sudo ldconfig
```
wsjt-x
Implements digital communication protocols or "modes" called FT4, FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. Has comprehensive rig control using hamlib.
- Prerequisites - pulseaudio, which should already be installed.
```
sudo apt-get install gcc g++ gfortran libgfortran5 libpulse-dev pulseaudio subversion libreadline-dev libudev-dev
#Only if you did not install Hamlib:
#sudo apt-get install libhamlib-dev
```
- Install
  - Download the latest source tarball from http://physics.princeton.edu/pulsar/K1JT/wsjtx.html and save it in your home directory.
  - Assuming the archive is wsjtx-2.3.1.tgz, in a terminal window paste or type these commands. Installing from source instead of the packager version can give you the latest and will resolve QT5 conflicts if the packager version is different from what you have installed. This will take some time.
```
cd ~/
tar -zxvf wsjtx-2.3.1.tgz
cd wsjtx-2.3.1
mkdir build
cd build/
cmake -DWSJT_SKIP_MANPAGES=ON -DWSJT_GENERATE_DOCS=OFF ..
cmake --build .
sudo cmake --build . --target install
sudo ldconfig
```
  - Setting up WSJT-X for GridTracker
    
    In WSJT-X File / Settings / General tab, you will need to have your Callsign and Maidenhead Grid Square set, it is recommended to set your "MH6" grid square (eg: CN84NL vs CN84) for higher map and Spot reporting accuracy. Optionally you can enable "Double-click on call sets Tx enable" and "Disable Tx after sending 73"
    You can find your grid square at http://www.levinecentral.com/ham/grid_square.php
    
    On the Reporting tab, options "Prompt me to log QSO", "Clear DX call and grid after logging" and "Accept UDP requests" are required for GridTracker to function properly with WSJT-X. Not having these enabled can lead to frustration, lost logs and strange behavior in the Map view.
    
    It is recommended to "Enable PSK Reporter Spotting" to help other WSJT-X users as well as GridTracker users to know if they are propagating and give more data to the "Band Activity Graph" in your area.
GridTracker
- At this time, GridTracker is only available as a 32 bit application. Click here to set up compatibility with a 64 bit linux system.
  GridTracker works with this setup, but it has issues with some Chrome Remote Desktop extensions.
- Download the latest GridTracker from https://tagloomis.com/downloads/ or https://gridtracker.org/downloads/
  Extract it to your home directory so that the files are in /home/pi/GridTracker/.
  
  Open the README.txt file in the GridTracker folder which contains instructions on how to make a desktop launcher icon for GridTracker. A desktop file for this installation can be found in Adding programs to the Applications Menu
Soapy Remote
- Prerequisites - SoapySDR must be installed and...
```
sudo apt-get install avahi-daemon libavahi-client-dev
```
- Building Soapy Remote
  Soapy Remote allows you to fully access your SDR over your local network. CubicSDR works with this.
```
cd ~/
git clone https://github.com/pothosware/SoapyRemote.git
cd SoapyRemote
mkdir build
cd build
cmake ..
make -j 4
sudo make install
sudo ldconfig
```
- Launching the server in the terminal
```
SoapySDRServer --bind
```
  - Or specify a custom bind address:port as in these examples:
```
SoapySDRServer --bind="0.0.0.0:1234"

# IPv6 address URLs are also supported:
SoapySDRServer --bind="[::]:1234"
```
  - Substitute your IP address. My system defaults to port 55132.
TCP Server
- Building from Source Code
  A server for SDRplay devices to make the RSP IQ stream compatible with existing RTL based software and streaming methods.This software also has an extended mode to fully support all of the RSPs capabilities and 16bit IQ stream values.
```
cd ~/
git clone https://github.com/SDRplay/RSPTCPServer.git
cd RSPTCPServer
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig
```
