The New Kids on the Block: VR and AR

What Are VR and AR?

Virtual Reality (VR): Put on special goggles and you’re transported to a completely digital world.

Augmented Reality (AR): Look through special glasses or your phone, and digital information appears overlaid on the real world.

How Could These Help DXpeditions?

Virtual Reality Uses:

• Virtual site visits: “Visit” a DXpedition location before going there
• Training: Practice operating in a safe, simulated environment
• Remote participation: Let supporters “join” your DXpedition virtually
• Planning meetings: Team members worldwide can meet in virtual space

Augmented Reality Uses:

• Antenna tuning help: See SWR readings floating in your field of view
• Assembly instructions: Get step-by-step guidance overlaid on real equipment
• Band condition display: See propagation data while you operate
• Remote expert help: Let an expert “see through your eyes” to help troubleshoot

The Reality Check: Current Limitations

Why VR and AR aren’t everywhere yet:

1. Equipment issues:
   • Heavy and bulky
   • Batteries don’t last long
   • Expensive
   • Not built for outdoor use
2. Internet problems:
   • Need very fast internet connections
   • Most DXpedition sites have poor internet
   • Can be unreliable when you need it most
3. Practical concerns:
   • VR can be distracting during real contacts
   • Limited software designed for ham radio
   • Steep learning curve
4. Cost vs. benefit:
   • Current ham radio tools work very well
   • Hard to justify the expense for small improvements

Real Examples of VR/AR in Ham Radio

What’s happening now:

• Virtual hamfests during COVID-19 were very successful
• Some clubs hold meetings in VR spaces
• Mobile apps show basic AR overlays for frequency information
• Universities use VR to teach antenna theory

Small experiments:

• DXpedition teams testing AR for equipment troubleshooting
• Contest stations trying heads-up displays for band information
• Emergency groups exploring VR for training scenarios

What Does the Future Look Like?

Next 2-3 Years: Testing and Learning

• Lightweight AR glasses become available
• Better software designed specifically for ham radio
• Major DXpeditions start small experiments
• Costs come down significantly

5 Years from Now: Early Adoption

• Rugged equipment suitable for field use
• Reliable software with proven benefits
• Standard training programs available
• Integration with existing station equipment

10 Years Out: Mainstream Use

• Most major DXpeditions include VR/AR equipment
• Automatic antenna optimization using AR
• Virtual participation becomes common
• AI assistants help with station operation

Should You Care About This Now?

For Most Hams: Not Yet

The current proven technologies (remote control, digital modes, modern batteries) offer much better value for your money right now.

For Early Adopters: Start Small

• Try VR hamfest experiences
• Experiment with AR apps on your phone
• Follow developments in ruggedized equipment
• Consider learning VR/AR development skills

For DXpedition Planners: Stay Informed

• Monitor technology developments
• Budget for future upgrades
• Consider partnership opportunities with tech companies
• Plan for eventual integration

The Bottom Line

DXpeditions today benefit from incredible proven technologies that make operations more successful than ever before. Remote control, digital modes, advanced power systems, and internet tools are game-changers that work reliably in the field.

VR and AR represent exciting possibilities for the future, but they’re still experimental for our hobby. The hardware needs to get lighter, cheaper, and more rugged. The software needs to be designed specifically for amateur radio. And we need better internet connectivity in remote locations.

The smart approach: Master today’s proven technologies while keeping an eye on emerging ones. The future of DXpeditioning will likely blend the best of both worlds.

Remember: Technology serves our goals of making contacts and sharing our hobby. The latest gadget isn’t always the best tool for the job.

The future of DXpeditioning is being written now. Whether you prefer traditional methods or cutting-edge technology, there’s never been a more exciting time to be involved in amateur radio adventures.

Wavelog is a self-hosted PHP application designed for amateur radio operators to log their contacts efficiently. It is an enhanced fork of Cloudlog by 2M0SQL and provides a web-based interface that allows logging QSOs from anywhere with an internet connection. Wavelog supports integrations with various online services such as ClubLog, QRZ, eQSL, HRDLog, and LotW. It is built using CodeIgniter 3 and Bootstrap 5, making it a lightweight yet powerful solution for ham radio enthusiasts.

One of Wavelog’s key features is its compatibility with a Docker-based deployment, which simplifies installation and management. By running Wavelog in a Docker container, users can ensure a consistent and portable environment without worrying about dependency conflicts.

This guide will walk you through the steps to install Wavelog using Docker on a Linux-based system.

Prerequisites

Before proceeding, ensure that you have the following installed on your system:

• A Linux-based operating system (Debian, Ubuntu, CentOS, etc.)
• Docker and Docker Compose installed
• A stable internet connection

Step 1: Install Docker and Docker Compose

If Docker is not already installed, you can install it using the following commands:

sudo apt update
sudo apt install docker.io docker-compose-plugin -y

Enable and start the Docker service:

sudo systemctl enable --now docker

Verify the installation:

docker --version
docker compose version

Step 2: Create a Docker Compose File

Create a directory for Wavelog and navigate into it:

mkdir ~/wavelog && cd ~/wavelog

Create a new docker-compose.yml file:

nano docker-compose.yml

Copy and paste the following content into the file:

services:
  wavelog-db:
    image: mariadb:11.3
    container_name: wavelog-db
    environment:
      MARIADB_RANDOM_ROOT_PASSWORD: yes
      MARIADB_DATABASE: wavelog
      MARIADB_USER: wavelog
      MARIADB_PASSWORD: wavelog # <- Insert a strong password here
    volumes:
      - wavelog-dbdata:/var/lib/mysql
    restart: unless-stopped

  wavelog-main:
    container_name: wavelog-main
    image: ghcr.io/wavelog/wavelog:latest
    depends_on:
      - wavelog-db
    environment:
      CI_ENV: docker
    volumes:
      - wavelog-config:/var/www/html/application/config/docker
      - wavelog-uploads:/var/www/html/uploads
      - wavelog-userdata:/var/www/html/userdata
    ports:
      - "8086:80"
    restart: unless-stopped

volumes:
  wavelog-dbdata:
  wavelog-uploads:
  wavelog-userdata:
  wavelog-config:

Save and exit (CTRL+X, then Y, then ENTER).

Step 3: Start Wavelog

Run the following command to start Wavelog:

docker compose up -d

This will pull the required images and start the Wavelog instance. To verify that the containers are running, use:

docker ps

Step 4: Access Wavelog

Once the setup is complete, open your web browser and navigate to:

http://localhost:8086

If you are running this on a remote server, replace localhost with the server’s IP address.

Follow the on-screen setup instructions and use the database credentials specified in docker-compose.yml:

• Database Host: wavelog-db
• Database Name: wavelog
• Username: wavelog
• Password: (use the value set in MARIADB_PASSWORD)

Step 5: Configure Reverse Proxy (Optional)

If you are hosting Wavelog on a server and want to access it using a domain name, configure an Nginx reverse proxy. Below is an example Nginx configuration:

server {
    listen 80;
    server_name wavelog.example.com;
    location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_pass http://localhost:8086;
    }
}

Restart Nginx after applying the configuration:

sudo systemctl restart nginx

Step 6: Updating Wavelog

To update Wavelog, follow these steps:

docker compose down
docker pull ghcr.io/wavelog/wavelog:latest
docker compose up -d

This will pull the latest version and restart Wavelog with the new image.

Troubleshooting

Check logs for any issues:

docker logs --follow wavelog-main

If you need to increase logging details, edit config.php inside the Wavelog configuration volume.

Conclusion

By following these steps, you have successfully set up Wavelog using Docker for logging amateur radio contacts. This setup ensures a stable and scalable environment while simplifying updates and maintenance. Enjoy using Wavelog for your QSO logging needs!
