Ham Clock

For amateur radio operators, especially those engaged in portable activities like SOTA, POTA, or contesting, organization and adherence to regulations are key. Ham Clock is a specialized Android application designed to streamline these portable operations by providing a centralized, highly readable display of critical information right on your device's screen.

What is Ham Clock?

Ham Clock is a purpose-built utility app for amateur radio operators that consolidates timekeeping and activity logging onto a single, customizable screen. Its core value lies in replacing scattered notes and manual timers with an integrated solution that enhances operational efficiency and ensures compliance with licensing regulations during field operations. By focusing on the specific needs of the portable operator, Ham Clock turns a standard Android device into a dedicated station management tool.

Centralize Your Portable Operation Data at a Glance

The app's main screen is designed for maximum clarity, presenting all essential data without clutter. It displays both local and GMT date and time with configurable formats, including an option to show seconds. This is complemented by four user-definable note fields, allowing you to record vital details such as your QTH locator, summit reference, callsign, or event information in one easily accessible place.

Never Miss a Mandatory Callsign Transmission

A standout feature for operators in regions with specific regulatory requirements is the integrated transmission reminder. Ham Clock can be configured to display a pop-up notification every 10 minutes, serving as a prompt to transmit your callsign as mandated by licensing rules in some countries. An optional audible notification can accompany the visual alert, ensuring you never overlook this critical procedure even when your attention is divided.

Organize and Recall Your Favorite Activation Details

Efficiency in the field is boosted by the app’s robust note management system. You are not limited to a single set of notes; Ham Clock allows you to create, save, and load multiple note profiles. This means you can pre-configure details for your favorite activation sites or common events, and load them instantly when you arrive on location, saving valuable time and preventing data entry errors.

Optimize Readability for Any Field Condition

Understanding the challenges of outdoor use, Ham Clock prioritizes readability. It uses large, high-contrast fonts to ensure the display is clear even in bright daylight. The app offers both light and dark color schemes, allowing you to choose the best option for your environment and conserve battery life if desired. You can also hide the local clock to maximize the screen space dedicated to your notes.

Seamlessly Share and Backup Your Logging Data

The app facilitates easy data management through its sharing function. You can export the content of your notes as a simple, well-formatted text file (JSONArray). This file, with a `.hctxt` extension, can be easily shared via Gmail or Google Drive for backup or further analysis. When opened in Gmail on another device with Ham Clock, the app intelligently recognizes the file format and offers to import the data directly.

MOD Features: Enhanced Functionality

For users seeking to unlock the full potential of Ham Clock, a modified (MOD) version of the app is available. This version typically provides:

  Ad-Free Experience: All advertisements are completely removed, offering an uninterrupted, focused interface.

  Unlocked Premium Features: Gain access to all advanced configuration options and customization settings without restriction.

  Enhanced Export Capabilities: Unlock additional data export formats and sharing methods for greater flexibility.

These enhancements transform Ham Clock into a completely seamless professional tool, removing distractions and providing full control over your portable operating setup.

Conclusion

Ham Clock successfully addresses the unique logistical challenges faced by portable amateur radio operators. By integrating time display, regulatory reminders, and flexible note-taking into a single, daylight-readable application, it significantly improves efficiency and confidence during activations. Its thoughtful design and focus on real-world usability make it an indispensable tool for anyone taking their radio into the field.
