Imagine operating your entire ham radio station remotely — from anywhere in the world — using only a web browser and a Raspberry Pi. Sounds futuristic? Not anymore.

Introducing Simple Ham Radio Remote (SimpleHRR) — a lightweight, browser-based web app designed for amateur radio operators who want to remote control their transceivers over the Internet. Whether you’re using a PC, laptop, Android phone, or iPhone (Safari tested), SimpleHRR brings your station to your fingertips — no extra software, no complex wiring, no subscription fees.

What Is SimpleHRR?

SimpleHRR (Simple Ham Radio Remote) is a web-based remote control system hosted on a low-cost Raspberry Pi (or Le Potato) that connects directly to your amateur radio transceiver via USB and your home network via Ethernet.

No SCU-LAN10.
No Remote Desktop.
No TeamViewer.
Just a browser — that’s it.

Key Features

• Full Radio Control: Power, Band, Mode, VFO, TX/RX settings, filters, notch, gain — everything is right there.
• Two-Way Audio: Talk and listen directly from the browser — no need for Mumble, Skype, or other VOIP software.
• Integrated Webcam Feed: Keep an eye on your shack or monitor your equipment remotely.
• Web Server Included: Host your own station schedule or control page.
• Multi-User Support: Set up individual accounts for club members or shared stations.
• Browser-Based UI: Fully functional interface using mouse wheel and keyboard shortcuts (e.g., spacebar for PTT).
• Smart Fail-Safe: Automatically turns off radio if the connection drops — no risk of accidental transmissions.

Radios Supported

Currently tested with:

Icom: IC-7300, IC-7610, IC-705 (HF/VHF/UHF), IC-2730A
Yaesu: FT-710, FT-2000, FT-950, FT-450

Thanks to its use of CI-V and CAT protocols, many other radios may also work out of the box.

Why SimpleHRR?

• No Subscription Fees – It’s free and open for all hams.
• Headless Setup – No monitor or keyboard required. Just flash the prebuilt image to a microSD card and go.
• Runs on Raspberry Pi or Le Potato – Inexpensive, low-power devices make the setup super affordable.
• LAN + WiFi + Internet – Connect locally or remotely. Even works with mobile WiFi hotspots.

Setup Requirements

• Raspberry Pi 4 (or similar SBC)
• Raspbian Lite (preloaded image provided)
• USB cable for your radio
• 8GB or larger microSD card
• 5V power supply
• Network connection (LAN/WiFi)

Use your favorite microSD flashing tool, boot up the Pi, and access your remote shack via browser login — it’s that easy.

Works With:

• Google Chrome
• Mozilla Firefox
• Safari (tested on iPhone 12)
• Any modern web browser

Use Case Example: Remote Control the Icom IC-7300

With just a Raspberry Pi 4 and a USB cable, you can remotely:

• Power on/off your IC-7300
• Select bands and modes
• Use VFO tuning and filters
• Transmit and receive with integrated audio
• Monitor your shack with a webcam

All through a clean, intuitive web interface.

Why Docker?

Docker allows you to deploy software in isolated containers, complete with all their dependencies. This means you don’t need to worry about library conflicts, system packages, or compiling from source—just pull the image and run.

The Docker images provided by jketterl on Docker Hub are built specifically for OpenWebRX and include all necessary requirements out of the box. Images are available for a range of hardware types, and there’s even a comprehensive “full” variant that supports multiple SDR devices.

These images are built for multiple architectures:

• x86_64 (most desktops/laptops)
• armv7l and aarch64 (perfect for Raspberry Pi and similar single-board computers)

Quick Start for Raspberry Pi

If you haven’t installed Docker yet, the easiest way is to run:

curl -sSL https://get.docker.com | sh

Once Docker is installed, you’re just two commands away from getting OpenWebRX up and running:

docker volume create openwebrx-settings
docker run --device /dev/bus/usb -p 8073:8073 \
  -v openwebrx-settings:/var/lib/openwebrx \
  --tmpfs=/tmp/openwebrx \
  jketterl/openwebrx:stable

This setup does the following:

• Maps USB access so your SDR hardware can be used inside the container
• Creates a persistent volume for OpenWebRX settings
• Offloads temporary files to memory (tmpfs) to reduce SD card wear, which is especially important on Raspberry Pi

Docker Compose Option

If you prefer docker-compose, here’s a minimal docker-compose.yml setup:

version: "3"
services:
  openwebrx:
    image: jketterl/openwebrx:stable
    volumes:
      - ./openwebrx/settings:/var/lib/openwebrx
    ports:
      - "8073:8073"
    devices:
      - "/dev/bus/usb/002/002:/dev/bus/usb/002/002"
    tmpfs:
      - "/tmp/openwebrx"

Make sure to adjust the USB device path according to your system. You can check your SDR device’s path using lsusb and ls /dev/bus/usb.

Troubleshooting: USB Device Access

Some users run into issues when the SDR device cannot be accessed inside the Docker container. This usually shows up as an error like:

usb_claim_interface error -6

This happens when the Linux kernel loads its own drivers for your SDR, preventing access from within Docker.

To solve this, you’ll need to blacklist the appropriate kernel modules on your host system. Here’s a quick reference:

On Debian-based systems:

Create a file in /etc/modprobe.d/, such as sdr-blacklist.conf, and add lines like:

blacklist dvb_usb_rtl28xxu

After that, run sudo update-initramfs -u and reboot your system to apply the changes.

Final Notes

This containerized approach to running OpenWebRX is efficient, maintainable, and easy to back up or migrate. It’s ideal for both newcomers and experienced users alike. The Docker images by jketterl are actively maintained and support a variety of SDR hardware, making them a solid choice for any SDR setup.

If you’re looking to get your SDR receiver online with minimal configuration and maximum flexibility, this is the way to go. Visit https://github.com/jketterl/openwebrx
