Simon's World Map v1.1
Simon Brown • July 29, 2021
Introduction
I need a simple display which shows me at the very least:
- Current Time
- Sunrise / Sunset
- Greyline map
- DX stations
There are commercial geo clock solutions such as Geochron, but as a programmer with spare 4k monitors and computers I decided to write my own, that way I have exactly what I want.
Updates
Kit updated July 29th, 2021 to fix CPU usage problems.
What's New

A few days spent on this program in July 2021:
- Added the Explorer map - thanks to Nasa,
- Map can be dragged and zoomed with the mouse,
- Reworked the ribbon bar.
So it's time to call it v1.1.
The downloads will be hosted from sdr-radio.com later this year, for now you download from the author's own website.

After too much grief, I've decided to stop using Wi-Fi to connect the small NUC systems in the computer room to my network: DX Cluster (Ubuntu) SDR Server (Windows) User Forums (Windows) These servers are in constant use, causing the wireless transmitter on my TP-Link AX50 to fail. By switching over to a wired network there's less demand on the wireless transmitter and the whole network has become far more reliable. In future I will only use Wi-fi when there's no alternative. I'm keeping a spare router ready just in case the AX50 fails.
