While the RPi3B and NooElec Mini worked to a degree it was time to upgrade things to improve imaging. Stage 1 – Upgrade the Raspberry Pi3B to a Pi4 2GB

Stage 2 – Upgrade the Disconne to a QFH antennna The build was based on the instructions from NOAA Satellite Signals With a PVC QFH Antenna and Laptop Made a few mods by making it in one piece for the verticle. The copper and coax were 400mm longer than the final length and then pulled back up through and joined at the top.

Stage 3 – Update the software for the RPi. The software needed updating to provide remote images to be viewed and managed via a webpage. To this end there is available the Raspberry NOAA V2 software. This is a spinoff of the original raspberry-noaa created by Nico It requires a bit of text editing but no actual programming.
Sample from install: Don’t want all the nitty-gritty details? Here’s the quick-start – if you have questions, continue reading the rest of this README or reach out by submitting an issue:
# update os localisation settings
# install git
sudo apt-get -y install git
# clone repository
git clone https://github.com/jekhokie/raspberry-noaa-v2.git
# copy sample settings and update for your install
cp config/settings.yml.sample config/settings.yml
# perform install
Next stage was to be able to view the images via the internet, which was done by running a small Apache webserver on the RPi and allowing you to view the files stored in a directory. While this was ok it was a bit clunky and you needed to download the whole file which could be a bit on the large side.
While the Disconne antenna was “ok” it wasn’t really up to the job as it is a generic frequency range antenna so it was time for an upgrade.
