Best SDR for Raspberry Pi: RTL-SDR, ADS-B, AIS, Satellites, and Remote Monitoring

Updated: June 2026. This guide compares the best SDR hardware and software for Raspberry Pi projects, including ADS-B aircraft tracking, AIS ship tracking, weather satellites, remote radio listening, rtl_tcp streaming, OpenWebRX, antennas, and multi-dongle setups.

A Raspberry Pi and an SDR receiver can become a compact radio station that runs quietly around the clock. Connect a suitable USB SDR dongle, install the correct software, add an antenna, and the Raspberry Pi can track aircraft, receive ship positions, decode satellite transmissions, monitor radio spectrum, or provide remote browser access to a receiver installed near a better antenna location.

The best SDR for Raspberry Pi is usually not the most expensive radio. For most projects, an RTL-SDR Blog V3 is the smartest starting point. It is affordable, mature, Linux-compatible, and flexible enough for ADS-B, AIS, VHF and UHF monitoring, weather satellites, radiosondes, remote listening, and general SDR learning.

More advanced SDRs can still make sense. SDRplay and Airspy receivers are useful when reception quality matters more than price. HackRF and PlutoSDR platforms are useful for development projects. However, beginners should start with the simplest receiver that matches the first project they actually want to build.

This guide explains which Raspberry Pi model to use, which SDR receiver to buy, which antenna matters for each project, and how to choose between ADS-B, AIS, satellites, OpenWebRX, and rtl_tcp remote monitoring.

To compare general SDR options first, read our Best SDR Receivers in 2026: RTL-SDR, SDRplay, Airspy, HackRF, PlutoSDR, and More guide.

Quick Answer: What Is the Best SDR for Raspberry Pi?

For most Raspberry Pi projects, choose the RTL-SDR Blog V3 Kit.

It is the best all-purpose starting point because it works on Linux and Raspberry Pi, includes a multipurpose antenna set, and can be used for several projects before you need specialist hardware.

Your Raspberry Pi SDR Project	Best Starting SDR	Recommended Raspberry Pi	Main Software
ADS-B aircraft tracking	RTL-SDR Blog V3 with a dedicated 1090 MHz antenna	Raspberry Pi 4 or 5	dump1090 and PiAware
AIS ship tracking	RTL-SDR Blog V3 with a VHF or AIS-tuned antenna	Raspberry Pi 3B+, 4, or 5	AIS-catcher
Weather satellite reception	RTL-SDR Blog V3 Kit with a suitable 137 MHz antenna	Raspberry Pi 4 or 5	SatDump
Remote web SDR receiver	RTL-SDR Blog V3, SDRplay, or another supported receiver	Raspberry Pi 4 or 5	OpenWebRX
Raw IQ streaming over a local network	RTL-SDR Blog V3	Raspberry Pi 4 or 5 with Ethernet	rtl_tcp
Multiple simultaneous stations	Multiple serialized RTL-SDR dongles	Raspberry Pi 5 preferred	Separate decoder services for each receiver
Advanced SDR development	HackRF, ADALM-PLUTO, PLUTO+ SDR, USRP, or bladeRF	Raspberry Pi 5 or a more powerful host depending on workload	GNU Radio, SDRangel, or custom software

Why Use a Raspberry Pi for SDR?

A Raspberry Pi is useful because it can remain close to the antenna while you access the radio data from another device.

This can improve a station in several ways:

The Raspberry Pi can run continuously without keeping a desktop computer powered on.
The SDR can be installed closer to the antenna, reducing long coaxial-cable losses.
Aircraft, ship, and satellite data can be decoded automatically.
A browser interface can provide access from another computer, tablet, or phone.
Multiple SDR dongles can run separate services on one compact server.
Ethernet and Wi-Fi allow the receiver to operate from a better antenna location.
Logs, maps, decoded data, and statistics can be stored or forwarded automatically.

A Raspberry Pi does not improve the radio sensitivity by itself. The antenna, placement, cable loss, filtering, software settings, and SDR receiver still determine the result.

Best Raspberry Pi Model for SDR Projects

Raspberry Pi 4 and Raspberry Pi 5 are both useful SDR hosts. The best choice depends on how much processing your project needs.

Raspberry Pi Model	Best For	Recommendation
Raspberry Pi 3B+	Lightweight dedicated services such as a basic AIS receiver	Usable when already owned, but not the best new purchase for a multi-purpose station
Raspberry Pi 4	ADS-B, AIS, rtl_tcp, OpenWebRX, and basic satellite stations	Best value choice for a dedicated single-purpose SDR server
Raspberry Pi 5	Multiple SDR dongles, multiple decoder services, heavier processing, remote monitoring, and more demanding satellite workflows	Best overall choice for a new expandable SDR station
Raspberry Pi Zero W family	Very lightweight headless projects where low power matters	Use only when the software workload is known to be modest

Why Raspberry Pi 4 is still enough for many SDR stations

Raspberry Pi 4 includes Gigabit Ethernet, two USB 3.0 ports, two USB 2.0 ports, dual-band Wi-Fi, and enough processing power for many dedicated receiver services.

It remains a practical choice for:

One RTL-SDR running PiAware for ADS-B
One RTL-SDR running AIS-catcher
A basic OpenWebRX receiver
An rtl_tcp server on a wired local network
A modest satellite-decoding station

Why Raspberry Pi 5 is the better new purchase

Raspberry Pi 5 adds a faster 2.4 GHz quad-core processor and higher-performance USB capabilities. This makes it the safer choice when the station will grow over time.

Choose Raspberry Pi 5 when you want to:

Run ADS-B and AIS simultaneously with separate dongles
Decode satellites while running other services
Use multiple RTL-SDR devices
Host OpenWebRX for several users
Store large amounts of decoded data
Use an NVMe drive
Run dashboards, databases, or additional network services

Best Overall SDR for Raspberry Pi: RTL-SDR Blog V3 Kit

The RTL-SDR Blog V3 Kit is the best default recommendation for most Raspberry Pi users.

It is not the newest SDR on the market, but it remains one of the easiest receivers to deploy reliably on a Linux-based system.

RTL-SDR Blog V3 key features

RTL2832U ADC chipset
R820T2 or R860 tuner family
Approximately 500 kHz–1.7 GHz tuning depending on mode and setup
Up to 3.2 MHz bandwidth, with approximately 2.4 MHz commonly treated as stable
HF reception through direct-sampling mode
1 PPM TCXO for improved frequency stability
SMA female antenna connector
Aluminium enclosure with passive cooling
Software-switchable bias tee for compatible active antennas and LNAs
Linux and Raspberry Pi compatibility

Why the kit version is useful for beginners

The kit adds a multipurpose dipole antenna set, cable, tripod mount, and suction-cup mount. This allows beginners to test ADS-B, VHF, UHF, satellites, and general radio reception before buying a specialist antenna.

If you already own antennas and cables, the RTL-SDR Blog V3 dongle-only version may be enough.

Read our full review: RTL-SDR Blog V3 Kit Review: Is It Still Worth Buying in 2026?

Why RTL-SDR Blog V3 Is a Safe Raspberry Pi Choice in 2026

Driver stability matters more on a headless Raspberry Pi station than on a desktop computer. You normally want the station to start automatically after a reboot and continue running without manual intervention.

RTL-SDR Blog V3 remains attractive because it is mature and widely supported by Linux SDR software.

In May 2026, RTL-SDR Blog announced that RTL-SDR Blog V4 is reaching the end of its production cycle because its R828D tuner is no longer manufactured. A limited V4 Lite using the R828S tuner is planned, but it will require updated drivers.

For a Raspberry Pi station that needs proven compatibility today, V3 remains the simplest recommendation.

Can One RTL-SDR Run Every Raspberry Pi Project?

One RTL-SDR dongle can be reused for many different projects, but it cannot normally receive widely separated frequencies at the same time.

For example:

ADS-B aircraft tracking commonly uses 1090 MHz.
AIS ship tracking normally uses 161.975 MHz and 162.025 MHz.
Meteor weather-satellite reception uses a different frequency range around 137 MHz.
Remote listening may require tuning across many other bands.

One dongle can tune to one relevant spectrum slice at a time. It can handle both AIS channels because they are close together, but it cannot simultaneously receive AIS near 162 MHz and ADS-B at 1090 MHz.

Use multiple SDR dongles when you want:

ADS-B and AIS running simultaneously
A permanent ADS-B receiver plus a separate general scanner
Two remote OpenWebRX bands
Simultaneous satellite reception and terrestrial monitoring
Separate 1090 MHz and 978 MHz aircraft receivers where applicable

When using multiple identical RTL-SDR dongles, assign a unique serial number to each device so every service opens the correct receiver after a reboot.

Best Raspberry Pi SDR Project for Beginners: ADS-B Aircraft Tracking

ADS-B aircraft tracking is one of the best first Raspberry Pi SDR projects. The station can run continuously, display nearby aircraft on a local map, and optionally contribute received data to services such as FlightAware.

In many regions, aircraft broadcast ADS-B messages around 1090 MHz. A Raspberry Pi running dump1090 decodes the received messages, while PiAware can display and forward the data.

Basic Raspberry Pi ADS-B hardware

Raspberry Pi 4 or Raspberry Pi 5
Suitable power supply
MicroSD card or NVMe storage where supported
RTL-SDR Blog V3 dongle
1090 MHz antenna
Optional 1090 MHz band-pass filter
Optional filtered LNA
Ethernet or Wi-Fi connection

Basic Raspberry Pi ADS-B software

dump1090 for decoding Mode S and ADS-B messages
PiAware for FlightAware integration
SkyAware for a local browser map
Optional dashboards and feeder software when needed

How Far Can a Raspberry Pi ADS-B Receiver Reach?

ADS-B range depends heavily on line of sight. Aircraft are elevated, which makes long-distance reception possible when the antenna has a clear view of the sky.

FlightAware explains that a PiAware station can often track aircraft within approximately 100–300 miles depending on the antenna installation. Its guide also notes that well-installed outdoor rooftop antennas can exceed 250 miles or 400 km.

These figures are not guaranteed. Real-world performance depends on:

Antenna height
Antenna tuning
Clear sky view
Cable loss
Nearby buildings and terrain
Local RF interference
Filtering
LNA placement

Improve ADS-B reception by:

Using a dedicated 1090 MHz antenna
Mounting the antenna outdoors or near a suitable window
Keeping coaxial cable runs short
Installing an LNA close to the antenna when appropriate
Adding a 1090 MHz filter in noisy urban environments
Using Ethernet for a reliable always-on station

Browse RTL-SDR receivers, antennas, filters, and accessories.

Best Raspberry Pi SDR Project Near the Coast: AIS Ship Tracking

AIS ship tracking is a strong Raspberry Pi project for users near the sea, ports, navigable rivers, and busy waterways.

AIS transponders broadcast vessel information using two VHF channels:

AIS 1: 161.975 MHz
AIS 2: 162.025 MHz

An RTL-SDR receiver can capture both channels because they are close together. AIS-catcher then decodes the messages and can provide NMEA output or forward data over the network.

Basic Raspberry Pi AIS hardware

Raspberry Pi 3B+, 4, or 5
RTL-SDR Blog V3 receiver
VHF marine or AIS-tuned antenna
Suitable cable and SMA adapter
Ethernet or Wi-Fi connection
Optional AIS band-pass filter
Optional LNA where cable loss or weak signals justify it

Why use AIS-catcher?

AIS-catcher is a lightweight multi-platform dual-channel AIS receiver. It supports RTL-SDR, Airspy, HackRF, SDRplay, SoapySDR devices, files, and network inputs.

It can output NMEA messages and forward received data using UDP, HTTP, or TCP. It also includes a built-in web server for suitable local-network workflows.

Important AIS limitation

An RTL-SDR AIS station is useful for hobby monitoring, education, and data collection. Do not rely on a DIY SDR station as the only source of navigation or safety-critical information.

Best Raspberry Pi SDR Project for Satellites

Raspberry Pi and RTL-SDR can also become an automated satellite-reception station.

SatDump is one of the most useful current tools because it can record baseband data, process files later, decode supported satellite signals live, schedule passes, and generate satellite products.

Beginner satellite project: Meteor LRPT

A practical beginner workflow is Meteor LRPT reception around 137 MHz when a suitable active satellite is available.

A basic setup includes:

Raspberry Pi 4 or Raspberry Pi 5
RTL-SDR Blog V3 Kit
V-dipole, QFH, or another antenna suitable for the satellite frequency
Current SatDump software
Clear view of the sky during the pass
Optional filter and LNA where appropriate

Why Raspberry Pi is useful for satellites

It can run unattended.
It can schedule passes.
It can store recordings.
It can process received data automatically.
It can remain close to the antenna.
It can provide remote access to generated images.

Read our full guide: SatDump V2 with RTL-SDR: Complete Beginner Setup Guide

Can Raspberry Pi Receive Geostationary Weather Satellites?

A Raspberry Pi can be used in more advanced geostationary satellite stations, but these setups require specialist hardware.

Depending on the satellite and region, the station may need:

A directional dish or grid antenna
A suitable feed
A filtered LNA
Low-loss coaxial cable
An SDR receiver covering the required frequency
Stable power
Careful alignment
SatDump or another compatible decoder

Start with a lower-cost 137 MHz satellite project before building a permanent dish-based station.

Best Raspberry Pi Remote SDR Software: OpenWebRX

OpenWebRX turns a Raspberry Pi and SDR receiver into a browser-accessible radio station.

Users can access the receiver through a web browser without installing SDR software on every client device. This makes OpenWebRX useful for a receiver installed at a remote antenna site, a classroom, a radio club, or a home server.

OpenWebRX is useful for:

Remote HF listening
VHF and UHF monitoring
Sharing a receiver with several users
Accessing an antenna installed at a quieter location
Using a browser instead of a desktop SDR application
Creating a radio-club receiver
Teaching radio concepts
Monitoring from a phone or tablet

Basic OpenWebRX setup

Choose Raspberry Pi 4 or Raspberry Pi 5.
Connect the SDR receiver by USB.
Attach an antenna suitable for the target bands.
Install an official OpenWebRX Raspberry Pi image or use the supported package route.
Connect the Raspberry Pi to the network.
Open the OpenWebRX interface in a browser.
Create receiver profiles for the bands you want to monitor.
Secure remote access carefully before exposing the service outside your local network.

Use Ethernet when possible

Ethernet is normally the better choice for a permanent remote receiver. It reduces the chance of wireless interruptions and makes raw sample streaming more reliable.

OpenWebRX is available from the official OpenWebRX website.

Alternative Remote Method: rtl_tcp

rtl_tcp is a command-line utility included with the RTL-SDR toolset. It turns a Raspberry Pi connected to an RTL-SDR receiver into a raw IQ spectrum server.

A compatible application on another computer connects over the network, tunes the dongle, and receives I/Q sample data for demodulation, decoding, or logging.

Use rtl_tcp when:

You want the SDR physically close to the antenna.
You want to control the receiver from another computer.
You already use an SDR application that supports rtl_tcp.
You want raw I/Q data rather than a browser interface.
Your local network is fast and reliable.

Prefer OpenWebRX when:

You want a browser interface.
You want easier access from phones and tablets.
You want to share the receiver with multiple users.
You do not need raw IQ data on the client device.
You want server-side radio processing.

Network warning for rtl_tcp

Raw IQ streaming can use substantial bandwidth. Use a reliable wired network where possible. Do not expose an rtl_tcp service directly to the public internet without appropriate network protection.

OpenWebRX vs rtl_tcp

Feature	OpenWebRX	rtl_tcp
Main interface	Web browser	Compatible SDR client application
Where processing happens	Mainly on the server	Raw IQ data is forwarded to the client
Best network type	Ethernet or stable Wi-Fi	Fast Ethernet strongly preferred
Multiple users	Designed for shared browser access	Normally simpler single-client raw-IQ use
Best for beginners	Yes	Better for users familiar with SDR networking
Best use	Remote browser listening	Remote desktop SDR control and raw sample streaming

Best SDR for Raspberry Pi AIS and ADS-B at the Same Time

Use two separate RTL-SDR dongles.

ADS-B at 1090 MHz and AIS near 162 MHz are too far apart for one RTL-SDR receiver to handle simultaneously.

Recommended dual-dongle setup

Dongle	Frequency	Purpose	Software
RTL-SDR 1	1090 MHz	Aircraft tracking	dump1090 and PiAware
RTL-SDR 2	161.975 MHz and 162.025 MHz	Ship tracking	AIS-catcher

Raspberry Pi 4 can handle a carefully configured station. Raspberry Pi 5 is the safer new purchase when you also want dashboards, additional feeds, databases, or remote access.

Use unique serial numbers

Assign a unique serial number to every RTL-SDR dongle. This prevents services from selecting the wrong receiver after rebooting or reconnecting USB devices.

Best SDR for Raspberry Pi Remote Monitoring

RTL-SDR Blog V3 is the best first option for most remote monitoring setups.

It is inexpensive enough to dedicate permanently to a service and flexible enough to repurpose later.

Remote Monitoring Goal	Recommended SDR	Why
ADS-B aircraft map	RTL-SDR Blog V3	Affordable and suitable for 1090 MHz reception
AIS vessel map	RTL-SDR Blog V3	Can receive the two closely spaced AIS channels
Browser-accessible radio receiver	RTL-SDR Blog V3 or a supported receive-only upgrade	Works with OpenWebRX
Raw IQ streaming	RTL-SDR Blog V3	Works with rtl_tcp
Dedicated weak-signal HF remote receiver	SDRplay or Airspy receiver where supported by the software stack	Stronger receive-only performance for more specialized listening

Can You Use SDRplay or Airspy with Raspberry Pi?

Yes, but software support should be checked for the exact receiver and application before buying.

SDRplay and Airspy receivers can make sense when you want better receive-only performance than a basic RTL-SDR dongle.

Consider SDRplay when:

You want wider spectrum visibility.
You want improved general-coverage listening.
You are building a more serious desktop or remote receiver.
Your selected Linux and Raspberry Pi software stack supports the model.

Consider Airspy when:

You prioritize VHF and UHF receiving quality.
You want a stronger specialist receiver.
You need a compact receive-only upgrade.
Your chosen software supports the device.

For a first Raspberry Pi SDR project, RTL-SDR remains easier and less expensive.

Should You Use HackRF or PlutoSDR with Raspberry Pi?

HackRF and PlutoSDR-style devices are useful for development, but they are not the first recommendation for ADS-B, AIS, or a basic remote receiver.

Choose HackRF when:

You want wide frequency coverage.
You are building controlled RF experiments.
You need authorized transmit capability.
You use GNU Radio or custom tools.
You understand the additional software and processing requirements.

Choose PLUTO+ SDR when:

You want two transmit and two receive channels.
You need Gigabit Ethernet.
You want SDRangel or GNU Radio development.
You are building digital-communications experiments.
You need a more advanced network-connected platform.

SDRstore.eu offers the PLUTO+ SDR AD9363 2T2R Transceiver with Gigabit Ethernet.

Read our review: PLUTO+ SDR Review: AD9363 2T2R SDR Transceiver with Ethernet and 70 MHz–6 GHz Coverage

Raspberry Pi SDR Storage: MicroSD or NVMe?

Storage requirements depend on the project.

Project	Storage Recommendation
Simple ADS-B station	A reliable microSD card is normally enough
AIS receiver	A reliable microSD card is normally enough
OpenWebRX receiver	MicroSD is adequate for a basic station; NVMe may improve durability for heavier logging
Satellite baseband recording	Use larger and faster storage
Multiple services with databases and dashboards	Consider NVMe on Raspberry Pi 5

Raw IQ recordings consume storage quickly. Record only the bandwidth and duration you actually need.

Raspberry Pi SDR Power Supply Tips

SDR stations can become unstable when the Raspberry Pi power supply is inadequate.

USB SDR dongles, external drives, cooling fans, and other accessories all draw power.

Power-supply checklist

Use a suitable power supply for your exact Raspberry Pi model.
Avoid low-quality USB cables.
Check for undervoltage warnings.
Use a powered USB hub if several SDR dongles or accessories draw too much current.
Do not power a high-current LNA or accessory blindly from the SDR bias tee.
Confirm voltage and current requirements before connecting active RF accessories.

Should You Use USB 2.0 or USB 3.0?

RTL-SDR works through USB 2.0, but the Raspberry Pi USB layout still matters when you connect several devices.

Practical USB advice

One RTL-SDR dongle can run comfortably from a suitable USB port.
Use separate ports for multiple dongles.
Use short USB extension cables when dongles block adjacent ports.
A powered USB hub can help larger installations.
Keep USB cables away from antennas where possible.
Use unique serial numbers for identical SDR dongles.

Use Ethernet for Permanent SDR Stations

Wi-Fi is convenient, but Ethernet is usually better for an always-on Raspberry Pi receiver.

Ethernet is especially useful for:

rtl_tcp raw IQ streaming
OpenWebRX public or multi-user stations
Satellite recording servers
Remote antenna sites
Stations that upload data continuously
Multiple simultaneous decoder services

Wi-Fi remains suitable when installing a cable is impractical and the network is stable.

Choose the Right Antenna for Each Raspberry Pi SDR Project

The antenna often matters more than the Raspberry Pi model.

Project	Target Frequency	Recommended Antenna Direction
ADS-B aircraft tracking	1090 MHz in many regions	Dedicated 1090 MHz outdoor antenna for best results
AIS ship tracking	161.975 MHz and 162.025 MHz	AIS-tuned or suitable VHF marine antenna
Meteor LRPT satellite reception	Around 137 MHz	V-dipole, QFH, or another suitable satellite antenna
General VHF and UHF scanning	Depends on the band	Wideband antenna or band-specific antenna
HF listening	Below 30 MHz	Long wire, loop, dipole, or another HF-capable antenna
Remote OpenWebRX station	Depends on receiver profiles	Antenna or switched antenna system designed for the selected bands

Browse antennas and RF accessories at SDRstore.eu.

Do You Need a Filter or LNA?

Add filters and LNAs only when they solve a specific problem.

Use a filter when:

Strong FM broadcast signals overload the receiver.
Nearby mobile-network signals reduce ADS-B performance.
You want to isolate the 1090 MHz ADS-B band.
You want to isolate AIS frequencies near 162 MHz.
Strong AM broadcast stations affect HF reception.

Use an LNA when:

The target signal is weak.
The antenna cable introduces loss.
The LNA can be installed near the antenna.
The receiver is not already overloaded.
The LNA and bias-tee requirements are understood.

An LNA installed beside the Raspberry Pi after a long lossy cable may not help as much as an LNA placed near the antenna.

Use a NanoVNA to Test SDR Antennas

A NanoVNA can help confirm whether an ADS-B, AIS, LoRa, satellite, VHF, or UHF antenna is tuned correctly.

It can measure SWR, impedance, return loss, and resonant frequency when the analyzer covers the target band.

Read our guide: How to Test Antenna SWR with a NanoVNA

Advanced development	Raspberry Pi 5 or more powerful host with PLUTO+ SDR, HackRF, USRP, or bladeRF	GNU Radio, SDRangel, and custom signal-processing projects

Common Raspberry Pi SDR Problems and Fixes

The RTL-SDR dongle is not detected

Try another USB port, check the power supply, reconnect the dongle, and confirm that Linux detects the USB device. If the default DVB-T driver claims the device, follow the RTL-SDR software instructions for your distribution.

The service works until the Raspberry Pi reboots

Confirm that the service is enabled to start automatically. When several RTL-SDR receivers are connected, assign unique serial numbers and configure every service to open the correct device.

ADS-B range is poor

Move the antenna higher, improve its view of the sky, reduce coaxial-cable loss, add a suitable filter in noisy locations, and consider a filtered LNA close to the antenna.

AIS reception is inconsistent

Check the antenna, antenna height, distance from the coast or waterway, VHF cable loss, local interference, and AIS-catcher gain settings. Use an antenna suitable for the AIS channels near 162 MHz.

Satellite images contain noise or gaps

Confirm the satellite pass elevation, antenna orientation, gain settings, USB stability, CPU load, storage speed, and whether the decoder uses the correct pipeline.

rtl_tcp audio breaks up

Use Ethernet, reduce the sample rate, close unnecessary network traffic, and confirm that the client device can process the stream reliably.

OpenWebRX feels slow

Reduce unnecessary receiver profiles, limit simultaneous users, check CPU load, use Ethernet, and consider upgrading from Raspberry Pi 4 to Raspberry Pi 5 for heavier installations.

Two SDR services open the wrong dongles

Assign a unique serial number to every RTL-SDR and configure the software services to select the intended receiver explicitly.

The Raspberry Pi reports undervoltage

Replace the power supply or USB cable. Consider a powered USB hub when several dongles or external accessories are connected.

Raspberry Pi SDR Security Tips

Start with local-network access only.
Do not expose rtl_tcp directly to the public internet.
Use a VPN or another protected remote-access method when possible.
Change default passwords.
Install security updates.
Use firewall rules.
Back up configuration files.
Review which ports and services are accessible externally.
Use Ethernet for stable remote sites.

Legal and Privacy Notes

SDR reception rules vary by country. Receive only signals that you are legally allowed to monitor, decode, store, or forward.

ADS-B and AIS projects are valuable for learning and hobby monitoring. However, a DIY Raspberry Pi station should not be treated as a certified safety system or as the only source of navigation information.

Transmit-capable SDRs such as HackRF and PlutoSDR platforms should only be used for lawful and authorized transmissions with suitable filtering and RF engineering.

Do I need an LNA for ADS-B or AIS?

Not always. Add an LNA when signals are weak or cable loss is significant. Install it close to the antenna when practical and confirm its power and bias-tee requirements.

Should I use Ethernet or Wi-Fi for a Raspberry Pi SDR server?

Ethernet is better for permanent stations, rtl_tcp streaming, OpenWebRX, satellite recording, and multiple services. Wi-Fi remains suitable when the connection is stable and cabling is impractical.

Can I expose rtl_tcp directly to the internet?

Avoid exposing rtl_tcp directly to the public internet. Use a protected remote-access method such as a VPN and apply suitable firewall rules.

Is a Raspberry Pi SDR station safe to use for navigation?

A DIY Raspberry Pi AIS or ADS-B receiver is useful for learning and hobby monitoring, but it should not be treated as a certified safety system or the only source of navigation information.
