Installing drivers and support for the SDRplay RSP1A, HackRF One and RTL-SDR on a Raspberry Pi

On a newly installed 64 bit Raspberry Pi OS Debian Bookworm operating system.

I have found that this OS provides better performance than Debian or Ubuntu. I hope this helps you. These procedures may work for other SDR hardware except for the drivers and device specific items.

Note: I have included support for the SDRplay RSP1A, HackRF One and RTL-SDR. You will only need to install support for the device(s) that you have.

As of 11/24/2023, liquidsoap that can be used with op25 does not work. I hope this will be resolved soon.

Install Raspberry Pi OS

Download the latest 64-bit Raspberry Pi OS Bookworm image here: https://downloads.raspberrypi.org/raspios_arm64/images/
This procedure is developed for version 2023-12-05-raspios-bookworm-arm64. This procedure may not be appropriate for the next major version.
Install the image on a 32 GB or larger SD card. 16 GB may be large enough if you remove unused packages, etc. Use your favorite image program. Use Raspberry Pi Imager or balenaEtcher on Windows. For more help extracting and flashing the image, look on the image help page.
Boot the image in your Raspberry Pi. Allow it to go through the setup procedure, choosing localization settings, WiFi network, etc.
This procedure is written for a user named "pi".
Click Reboot

Change GPU memory allocation for Raspberry Pi 4

# Skip this section for Raspberry Pi 5.

sudo mousepad /boot/firmware/config.txt

Under:
[all]
# Add this line
gpu_mem=128

Under:
# Enable DRM VC4 V3D driver
If necessary, delete the "#" from #max_framebuffers= and change it to max_framebuffers=2

# Add this line
hdmi_enable_4kp60=1

Scroll bar configuration
Sometimes scroll bar behavior is different between applicatons and from what you may prefer. This procedure will make your scroll bar work more like most other operating systems.
Edit or create these files. You may change the values to your preference.

# If it does not exist, create ~/.config/gtk-3.0
mkdir -p ~/.config/gtk-3.0

mousepad ~/.config/gtk-3.0/settings.ini

# Insert the following into the file:

[Settings]
gtk-primary-button-warps-slider = false

# Save the file.

# Note that Raspberry Pi OS may delete gtk.css.

mousepad ~/.config/gtk-3.0/gtk.css

# Insert the following into the file:

.scrollbar {
    -GtkScrollbar-has-backward-stepper: true;
    -GtkScrollbar-has-forward-stepper: true;
    min-width: 18px;
    min-height: 18px;
}

scrollbar slider {
    /* Size of the slider */
    min-width: 14px;
    min-height: 14px;
    border-radius: 5px;

    /* Padding around the slider */
    border: 2px solid transparent;
}

# Save the file.

I suggest that you switch from Wayland to the Openbox window manager. With Wayland, there are GUI compatibility issues and CubicSDR will not run.

sudo raspi-config
Select Advanced Options
Select Wayland
Select X11  Openbox window manager with X11 backend
Tab to <OK> and press enter.
Press the ESC key
Tab to <Finish> and press Enter.
<reboot>

Run Start menu / Preferences / Raspberry Pi Configuration
- Click the Display tab.
  - Disable Screen Blanking, as it will halt your SDR reception.
- Click OK.

Before you begin

The automatic image installaton procedure should update your system, do it now if this did not occur and each day before installing software.
```
sudo apt update
sudo apt upgrade
```
Fix liquidsoap and add the multimedia repository for Trunk Recorder.
The Raspberry Pi optimised ffmpeg packages do not work with liquidsoap. This may be fixed in the future.

sudo mousepad /etc/apt/sources.list

# Add this line to the end of the file:
deb https://www.deb-multimedia.org bookworm main non-free
# Save and close

# Download the keys for the apt source and install them:

cd ~/Downloads
wget https://www.deb-multimedia.org/pool/main/d/deb-multimedia-keyring/deb-multimedia-keyring_2016.8.1_all.deb
sudo dpkg -i deb-multimedia-keyring_2016.8.1_all.deb

# Verify the package integrity with:
sha256sum deb-multimedia-keyring_2016.8.1_all.deb
# It should display this:

Before compiling software, set these compiler optimization flags. This must be repeated after a reboot or if you use a different terminal window. Note that with this optimization, this image may not boot on other Raspberry Pi hardware.

# For a 64-bit operating system on a Raspberry Pi 4:
export CXXFLAGS='-O3 -mtune=cortex-a72'
export CFLAGS='-O3 -mtune=cortex-a72'

# For a 64-bit operating system on a Raspberry Pi 5:
export CXXFLAGS='-O3 -mtune=cortex-a76'
export CFLAGS='-O3 -mtune=cortex-a76'

# For other operating systems:
export CXXFLAGS='-O3 -march=native -mtune=native'
export CFLAGS='-O3 -march=native -mtune=native'

SDRplay API Installation
If you upgrade to API 3.15 from an earlier version, it will break your system.
- Prerequisites
```
sudo apt install libusb-1.0-0 libusb-1.0-0-dev usbutils libfftw3-dev file
sudo service udev restart
```
- Download API 3.15.2 or later for Linux (64 bit) (3.15) from https://www.sdrplay.com/downloads/.
```
cd ~/Downloads # or wherever you downloaded the file
chmod 755 SDRplay_RSP_API-Linux-3.15.2.run
sudo ./SDRplay_RSP_API-Linux-3.15.2.run
sudo ldconfig
```
- To stop and start the API service, use the following commands...
```
sudo systemctl stop sdrplay
sudo systemctl start sdrplay
```
- Type lsusb. Bus 001 Device 003: ID 1df7:3000 or similar should be displayed.
- If you have SDRplay driver crashes, try this: msi2500 driver conflicts
HackRF One installation
- Prerequisites
  If you did not install these for SDRplay:
```
sudo apt install libusb-1.0-0-dev usbutils libfftw3-dev
```
- Install
```
cd ~/
git clone https://github.com/greatscottgadgets/hackrf
cd hackrf/host
mkdir build
cd build
cmake ..
make -j 4
sudo make install
sudo ldconfig
```
- Reboot
- You need to update the HackRF firmware if it does not match the version of the driver. As of this writing, the latest firmware/driver version was 2024.02.1
  Many HackRF devices have firmware version 2018.01.1 or earlier. Use hackrf_info to see if the firmware version matches the driver that you installed.
```
hackrf_info
```
  If you see "Firmware Version: 2024.02.1 (API:1.08)", then it is up to date and you do not need to do the firmware update shown below.
```
# Transfer rate test:
hackrf_transfer -r /dev/null -s 20000000

# Connect an antenna and test sending data:
hackrf_transfer -t /dev/zero
```
- Firmware updating instructions are based on this:
  https://hackrf.readthedocs.io/en/latest/updating_firmware.html#updating-the-spi-flash-firmware
  Note that the zip and tar.xz archives have the firmware files. The git clone procedure does not.
  
  Download hackrf-2024.02.1.zip
  Extract only the firmware-bin directory into the ~/hackrf directory
```
cd ~/hackrf/firmware-bin

# To update the firmware on a working HackRF One, use the hackrf_spiflash program:
hackrf_spiflash -w hackrf_one_usb.bin

# Press the reset button on the HackRF.
hackrf_info

# The new firmware version should now displayed.
# Perform the hackrf_transfer tests above.
```
Install the rtl-sdr driver
Based on a NESDR SMArt SDR. Others should be similar.
- Connect your rtl-sdr to your Raspbery Pi computer. In a terminal window, type lsusb. If it is working, you should see something similar to: Bus 001 Device 008: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
- We need to "blacklist" the default drivers. This is done by editing blacklist-dvb.conf:
```
sudo mousepad /etc/modprobe.d/blacklist-dvb.conf
```
- Add this line to the file:
  blacklist dvb_usb_rtl28xxu
  Save and close the file.
- ```
sudo apt-get install rtl-sdr librtlsdr-dev
```
- reboot
- Connect an antenna. In a terminal window, type rtl_test.
  This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine.
  Press CTRL-C to stop the test.

Install the Pulse Audio Volume Control
If you don't hear any audio, output may be on the incorrect audio device.

sudo apt-get install libpulse0 pulseaudio pavucontrol pulseaudio-utils libpulse-dev

# Optionally, for systems with Qt5 installed
sudo apt-get install libpulse0 pulseaudio pavucontrol-qt pulseaudio-utils libpulse-dev

Audio tuning (only tested on Raspberry Pi 4)

Edit /etc/pulse/daemon.conf. Copy it in case there are problems.

sudo mousepad /etc/pulse/daemon.conf

# Uncomment the line: enable-remixing = yes

# Find the following lines and change them as shown:
avoid-resampling = yes
default-sample-rate = 48000
default-fragments = 4
default-fragment-size-msec = 10

reboot
If you find that the operating system only has mono audio:
```
sudo mousepad /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf
```
