Ham Clock for PC

Keeping track of time across multiple zones and your portable radio notes on a single screen becomes practical when you run Ham Clock on a desktop or laptop. Amateur radio operators benefit from having UTC and local time side-by-side, along with space to jot down location details, callsigns, and activation info without switching between windows. The app's large font and high contrast make it easy to read in bright conditions, and desktop persistence means your notes and settings stay accessible throughout longer operating sessions.

Ham Clock brings core timekeeping and note-taking tools from mobile straight to your PC. The desktop version keeps the same clean interface (dual clocks, customizable date formats, dark and light themes) while giving you the freedom to position it alongside your logging software, email, or other radio-related windows. Running Ham Clock on a computer removes the portability constraint of a phone and lets you maintain a dedicated workspace for your amateur radio activities.

Core Clock and Display Features

Ham Clock displays your local date and time plus UTC (Zulu time) on a single view, critical for logging contacts and coordinating across time zones. The app offers configurable date formats to match your preference, a choice between light and dark color schemes for different lighting conditions, and adjustable display timeout to conserve resources when the window isn't in focus. Text is large and high-contrast by design, making it legible even in daylight or in a crowded shack. You can hide the local clock entirely to free up screen space for your notes.

Notes and Reminders Built In

The app provides up to four customizable note fields where you can record:

• Location name and QTH locator for portable activations
• Callsign and transmission reminder every 10 minutes
• Event details or contest information like SOTA, WCA, or POTA
• Activation specifics and other radio-related details
• Multiple saved note sets that you can switch between
• Optional ringtone alert when transmission reminder pops up

Sharing and File Management

Notes can be exported as simple text files in .hctxt format (a JSON structure readable in any text editor) and shared via Gmail or Google Drive. The sharing method works best with email; Gmail lets you open attachments directly without a separate download step. If you import a properly formatted note file, Ham Clock offers the choice to save or discard it. Bluetooth sharing is supported but can be unreliable across different Android versions and phone vendors. Ham Clock for Windows PC keeps all your data local: the app collects no personal information and includes no ads.

Why Ham Clock Suits Stationary Amateur Radio Work

Mobile operators often use Ham Clock on phones during portable activations, but desktop use creates a different advantage: a permanent, always-on reference panel for your shack. Running Ham Clock for computer setup letting you leave it visible while using logging software, digital modes, or chat tools. Operators report that the space-weather details (solar flux, K-index, and propagation forecasts) become more useful when visible throughout a long session, and the dual-time display prevents the mental math of converting between local and UTC. The alarm clock functionality serves double duty as both a transmission reminder and a session timer, helping maintain discipline during contests or extended operations.
