About Ham Clock
HamClock is targeted for portable amateur radio operators.
It displays time/date and user notes related to various portable locations on a single screen:
- Local date / time
- GMT date / time
- User notes
- Reminder to transmit callsign every 10 minutes, as required in some countries.
Note can be entered in up to four fields. Use it to record location name, QTH locator, callsign, activation details for SOTA, WCA, WFF or other activities, event info etc.
Multiple notes can be entered and saved for later use.
Note view is scrolled to show longer texts
Hide local clock, leaving even more room for notes
- Large font and contrast for readability in bright daylight.
- Light / dark color scheme
- Configurable date format
- Configurable display timeout.
- Optional popup every 10 minutes to remind you to transmit your callsign.
- Optional ringtone played along with the visual reminder. If you don't want audio alert, select "silent" or "none" ringtone.
- Share note content as a simple text file, formatted as JSONArray (string). Extension is .hctxt (HamClockTxt) but can be edited in any text editor.
Sharing works best via Gmail or GoogleDrive. With Gmail, open/receive directly from an attachment (no need to download the attachment first). If proper JSONArray file format is detected, "save or discard note" is offered.
Sharing via Bluetooth is less reliable on different devices, because android versions and phone vendors vary in trusted file types for BT transfers, and in permissions needed to access bluetooth storage space (received files).
Sharing via other applications is not tested, and it may or may not work.

A pretty handy app. But.. today in the U.S. its still 12/3/17 not 12/4/17 as shown. Can the date setting be changed for local calendars?

Nice clock, but we need to be able to adjust the text color. Black background and red text with the ability to adjust the brightness is what is needed for night time operations

Love the Loc/UTC time display. I have been licensed since 2000 and have had to keep a small clock next to my rig when operating. Now, I can use my phone. I think the grid square feature is nice if you're chasing your VUCC because it gives the direction. Really nice touch.

This is a great little app for any Amateur Radio operator who might ever do SOTA or other portable operation, and who wants to know UTC or Zulu time for log-keeping. In the past I have carried a small LCD clock or fiddled with a digital watch. This means the right UTC (or GMT) "Universal" time is always on my smart phone and, what's more, this free app even has a 10-minute timer built in (to remind me to send my ID at least once every ten minutes, as required by law.) Don't think about it, guys. It's a no-brainer. Just get the thing. And say, "Thank you, Zoran!" for making it gratis. :-)

Nice. It would be nice to have a full screen option (no title bar), a seconds display option, and an option to hide the notes so the times and dates fill the screen, or perhaps an option to resize the notes area in case you want a short note with larger clocks.

A clock that automatically shows correct Zulu time without having to set it for some location/timezone other than the one I am actually in. Bravo!!!

Labai gera programa, kai reikia matyti UTC laiką. Taip pat gali rodyti vietinį laiką ir pasirinktą statinį pranešimą. Reklamų nerodo.

This is really great for logging contacts where you always need the UTC at hand.

For some reason I cant figure out how to start the 10 minute call sign reminder. If would also be nice if you could make notes scroll or change from the notes to common Q codes that scroll to help learn and remember them. Still a nice clock

Nice and clean. Useful also for those who travel a lot. A widget is a must. Up, local time, down UTC...
