HamClock Alternatives: Web-Based Propagation Tools for Ham Radio Operators

With the recent announcement that HamClock has reached end-of-life and will cease to function in June 2026, many amateur radio operators are looking for alternatives to monitor propagation conditions, space weather, and DX activity. This guide explores web-based options that can fill that gap.

What Made HamClock Special

For years, HamClock by Elwood Downey (WB0OEW) was the go-to propagation dashboard for ham radio operators. Running on Raspberry Pi or desktop Linux, it provided a beautiful kiosk-style display combining:

• World map with gray line visualization
• Real-time DX cluster spots
• Space weather indices (solar flux, K-index, A-index)
• VOACAP propagation predictions
• Satellite tracking
• Contest calendars
• POTA/SOTA activity

The ham radio community owes a debt of gratitude to Elwood for creating and maintaining this remarkable tool for so many years.

DXLook: A Web-Based Alternative

DXLook.com is a free, web-based propagation platform that offers many similar capabilities without requiring dedicated hardware or software installation.

Key Features

Real-Time Propagation Data - Live spots from PSK Reporter, WSPRnet, and Reverse Beacon Network (RBN) - DX Cluster integration - APRS tracking - Visual representation of band activity worldwide

Space Weather Monitoring - Solar flux index (SFI) - K-index and A-index - X-ray flux levels - Geomagnetic storm alerts - Data sourced directly from NOAA APIs

VOACAP Propagation Predictions - Point-to-point path analysis - MUF predictions - Compare theoretical predictions against actual real-time reports - “Theory vs Reality” approach to understanding propagation

Interactive World Map - See where signals are being received in real-time - Filter by band, mode, or callsign - Gray line visualization - Maidenhead grid overlay

Advantages of a Web-Based Approach

What DXLook Does Differently

DXLook takes a different approach than HamClock in several ways:

1. Browser-based: Access from any device — desktop, tablet, or phone — without dedicated hardware
2. Real-time focus: Emphasis on live propagation reports rather than predictions alone
3. Theory vs Reality: Compare VOACAP predictions against actual spots to see how well models match real-world conditions
4. No maintenance: No SD cards to flash, no software to update, no operating system to maintain

Current Limitations

To be transparent, DXLook doesn’t replicate every HamClock feature:

• No satellite tracking (yet)
• No rotator control integration
• No local hardware sensor support (BME280, etc.)
• No kiosk mode for dedicated displays (though you can run it full-screen in a browser)

How to Get Started with DXLook

1. Visit DXLook.com
2. Enter your callsign and grid square
3. Start exploring real-time propagation data

No account required. No software to install. Works on any modern browser.

Other Alternatives Worth Considering

The ham radio community has several other tools that may help fill the HamClock gap:

• DXView (dxview.org) — Desktop application for DX cluster and propagation
• VOACAP Online (voacap.com) — Web-based propagation predictions
• PSK Reporter (pskreporter.info) — Real-time digital mode reception reports
• Space Weather Services — NOAA and various space weather dashboards
• Geochron 4K — Commercial alternative (paid)

For Raspberry Pi Users

If you have a Raspberry Pi dedicated to HamClock, you can repurpose it:

1. Open Chromium browser in kiosk mode
2. Point it to DXLook.com
3. Set to full-screen (F11)
4. Configure auto-start on boot

This gives you a similar always-on propagation display using your existing hardware.

The Future of Amateur Radio Propagation Tools

The end of HamClock marks a transition point for the amateur radio community. Web-based tools offer advantages in accessibility and maintenance, while dedicated applications provide deeper hardware integration.

DXLook continues to evolve with new features based on user feedback. The platform is supported entirely by donations from the amateur radio community, keeping it free and ad-free for all users.

DXLook is developed by AK6FP and serves over 4,800 monthly users worldwide. Visit DXLook.com to explore real-time propagation conditions.
