Ham Clock

HamClock: Your Radio Field Companion for Timekeeping, Logging, and Compliance

Fumbling with multiple apps while balancing my radio gear on a windswept hilltop, I nearly missed my activation window - until HamClock became my command center. That moment when both GMT and local time snapped into view on one uncluttered screen, relief washed over me like clear signal breaking through static. This isn't just another utility; it's the digital logbook I wish existed during my first SOTA attempt, now refined through countless field operations.

Dual Timezone Awareness

When coordinating across continents during portable events, the simultaneous GMT/local display prevents embarrassing miscalculations. I still remember activating a castle at sunset, watching both time zones tick toward golden hour when propagation peaked - no more mental gymnastics while adjusting antennas.

Location-Specific Note Matrix

The four-field notepad transforms chaotic scribbles into structured data. During last month's wildlife reserve activation, capturing grid square, species observed, and contact details felt like slotting puzzle pieces into place. That satisfying click when entering my callsign knowing it aligns perfectly with WFF requirements? Pure operational bliss.

Adaptable Screen Real Estate

Hiding the local clock when note-taking during night operations created precious space without sacrificing legibility. Scrolling through my activation records under headlamp light, the high-contrast display preserved night vision better than any paper log ever could.

Sunlight-Readable Interface

Midday on granite summits used to mean squinting at faded screens. Now the bold fonts cut through glare like a beacon - I actually chuckled seeing time displays remain crisp while sweat dripped onto the phone during a desert POTA session.

Regulatory Reminder System

The ten-minute call sign prompt rescued me from compliance anxiety during marathon sessions. When the subtle vibration pulses against my thigh during crowded park activations, it's discreet yet unmistakable - like a trusted copilot nudging my attention without disrupting the flow.

Dawn finds me on a foggy coastal cliff, salt spray misting the device as I swipe through dark mode interfaces. The screen glow stays subdued while I log tide conditions affecting propagation. Later, sharing .hctxt files via Gmail feels like passing a digital logbook - recipients instantly see my location notes formatted for their mapping software.

Post-sunset in my shack, reviewing the day's JSON files reveals something beautiful: HamClock's silent operation preserves the radio experience. No jarring notifications over weak signals, just that reliable pulse every ten minutes keeping me legal during those magical extended contacts.

Where it shines? Launch speed rivals emergency beacons - crucial when sudden weather changes demand quick pack-ups. The absolute privacy commitment means zero hesitation logging sensitive location data. But sharing via Bluetooth feels like tuning a temperamental antenna; sometimes it connects instantly, other times it stubbornly resists. I'd trade dark mode for adjustable font weights when my eyes tire after night operations.

For operators who've ever juggled stopwatches, paper logs, and reminder alarms simultaneously: this eliminates the clutter. It's become the bedrock of my portable kit - right beside the antenna tuner and extra batteries. Perfect for activators chasing summits before noon UTC or documenting rare species contacts at dusk.
