 title: Winlink on a Windows computer and a TX-500
 summary: >
-  Mission: move all my Winlink stuff from the linux notebook to
-  a Windows laptop...
+  For anyone interested and mainly for my notes archive, this is the setup that
+  I currently have set up on my Windows equipment for Winlink. I started taking notes
+  on the **Microsoft Surface 2 Go** and ended up installing all this on the **HP Elitebook 830 G6**
+  (which has an **integrated GPS sensor**).

+## Using the internal GPS sensor
+
+My Surface 2 Go was a non-LTE version and I think those versions are the only ones with built-in GPS sensors
+so I always had to use external GPS devices like the [U-blox7 GPS stick](https://www.amazon.com//dp/B01MTU9KTF/).
+
+But starting with the Elitebook 830 G6 I now have a device with integrated GPS sensors that I want to
+use with Winlink Express.
+
+Heads up: Winlink Express let you use a COM port or a TCP/IP connection to obtain coordinates, so we will
+need some sort of middleware that can read the internal sensors and forward the location information to a
+**virtual COM port**.
+
+### GPSREverse and GPSDirect
+
+I have tried [GPSReverse and GPSDirect](https://www.gpssensordrivers.com/) first but had no luck with it.
+
+I then started another try on a search engine but specifically looked for experienced off-grid operators like
+Julian, OH8STN -- because I remembered some videos of him using a Surface tablet as well. And of course, he
+[also used the internal GPS device of his LTE model](https://oh8stn.org/blog/2023/11/02/microsoft-surface-go-lte-gps-for-ham-radio/).
+
+### Using GpsGate Splitter
+
+Goto the [GpsGate Splitter](https://gpsgate.com/gpsgate-splitter) website and download the Splitter aswell as
+the **Windows Location API Plugin** (scroll down a bit).
+
+{{< alert >}}
+The program is a 14-day free trial and can be bought for EUR 30€ (USD 40$) and is well worth the
+investment.
+{{< /alert >}}
+
+On the welcome screen click <kbd>Advanced setup...</kbd> on the bottom. This opens the GpsGate settings dialog.
+Select <kbd>Windows Location API</kbd> as input.
+
+![screenshot of GpsGate input settings](gpsgate-input.png)
+
+Move to the tab <kbd>Output</kbd> and choose <kbd>Virtual COM Port</kbd> in the drop-down menu
+for the output. Click <kbd>Add</kbd> and choose which port to use (I use <kbd>COM1</kbd>).
+
+![screenshot of GpsGate output settings](gpsgate-output.png)
+
+Go back to the <kbd>Input</kbd> tab and click <kbd>Open</kbd>. You can now close the dialog
+form and it will remain active in the systray (bottom right of the screen, somewhere near the clock).
+
+After a reboot the GpsGate service should start automatically and restore your virtual COM port that
+you can select in Winlink Express.
