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This page is out of date.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This page is out of date.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
Terrys new video
Terry has done his first video as an Opto 22 employee. Pretty proud Dad here.
Terry doing Node-RED
Can’t believe that this has not been blogged about till now….. Last night, on my usual Tuesday night phone call with my Dad, I mentioned that Terry will be back at Opto for a winter internship. Dad asked what he will be doing, I said, just like his summer internship, he will be making videos,… Continue reading Terry doing Node-RED
