Titanium C1-PLL LNB GPSDO Modification for C-Band ADSC

This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ You may recall from the very end conclusion of the blog entry on my ADSC C-Band ground station that I had two outstanding issues. Tracking the sat. Thermal drift on the output. The sat issue is the nature of physics. The thermal… Continue reading Titanium C1-PLL LNB GPSDO Modification for C-Band ADSC

Finding out the feed ID from AircraftList.json

If you run a VRS (Virtual Radar Server) and want to explore your data a little more deeply, you might end up looking at the main output which is AircraftList.json. There is a very brief outline for what options you can append to it here; https://www.virtualradarserver.co.uk/Documentation/Formats/AircraftList.aspx But it does not tell you how to find… Continue reading Finding out the feed ID from AircraftList.json

Using Node-RED to read a HF propagation map

A few things to note. 1. This ‘trick’ should work for any sort of image that you need to compare color values. 2. I did not come up with the core code, I just asked the question. HF propagation is tricky. Thankfully a bunch of smart guys are running the show at the space weather… Continue reading Using Node-RED to read a HF propagation map

Tracking Inmarsat 4-F3 with Node-RED

This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ For a year now I have been ‘tracking’ Inmarsat 4-F3 for my C-Band ADSC aircraft receiving ground station. It has been very crude tracking, but tracking none the less. I used a linear actuator with a position feedback resistor. Its worth noting… Continue reading Tracking Inmarsat 4-F3 with Node-RED

Remote control of SDRuno with MQTT and Node-RED

This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ Getting back to looking at HF ACARS messages again and so with that comes the need to tune to the best HF frequency. (Best is still based on propagation and is a topic for another blog). My HF station is in Arizona,… Continue reading Remote control of SDRuno with MQTT and Node-RED
