    Got my 4K UHD TV and a wall mount. Just need to order the Geochron Digital and I will be in business. A long-time ham shack dream fulfilled at a fraction of the cost of the mechanical Geochron. Yes, it will work on any HD TV but resolution won't be nearly as sharp as the UHD TV. It uses WiFi for the time, as well as it tracks the ISS, has a map with all the ham radio call sign prefixes, now shows major shipping and airline routes, nighttime city lights and more. Man, once this beauty is installed, I will have to clean up my messy shack because this thing will just beg for visitors. My wife thinks I'm nutty but I told her the Geochron Digital will be so gorgeous that she'll want one for the living room too. (Major eye roll.)

    We used to go to a bar that had a GeoChron on the wall, and we would all watch it to see if the day / night overlay moved.

    A local restaurant used to have a Geochron on the wall. After eating, I'd always go over and admire the thing of beauty on the wall. And hope Santa would bring me one someday.

    Google turned up nothing on GridTracker & N0TLL. Can you share more info please?

    ah, hang on....
    The call in your post was transposed, it should be N0TTL, not TLL.
    Found it. It is not the same thing as GeoChron, but interesting. For other people,

    And how much RFI will all that screen produce? A lot, if my experiences with LED screens are anything to go by.

    My visualisation of the globe at any time of day is free. It's called a mental picture. But, of course, I'm not a dumb consumer.

    I guess that means the rest of us are dumb consumers. Thanks for the tip. I'll henceforth refrain from buying anything not on your approved list :)

    I have a 43 inch 4K UHD LCD in my shack and no noise at all. Plasma TVs were the real culprit there.

    GridTracker is very nice. Connected to WSJT-X you get real-time data. PSKReporter is also an option. Many options and data sources. This is a bit different than the GeoChron option - I definitely recommend DLing and playing around to learn its capabilities.

    I have 6 LED flood lights, 4 LED lamps, 4 LED monitors and a 70" LED TV [a cheap VIZIO] in the shack(don't judge and, yes, size matters :() - zero RFI. Not only is my shack fun to operate in - it's fun for guests to visit with lots of visual input to enhance radio operations.

    To each his/her own - enjoy your mental pictures, 73, Howard

    I’m impressed! $399 and change is more affordable.
    I’ve always wanted a GeoChrom map clock but I couldn’t justify $1300+
    The Geochron 4K UHD is more my budget, I just ordered one.
    And a Sony 42” 4K UHD TV.
    I remember when there was no color TV! I never saw a color TV until around 1966 when dad bought one from Sears and Roebuck!
    Who would have thought about digital UHD television back in the early 60’s?
    Currently I’m using a clock kit (GPS reference) from
