Capturing NOAA Satellite Images with SDR

October 31, 2018 Patrick Gilfeather

There are plenty of examples online (https://learn.adafruit.com/getting-started-with-rtl-sdr-and-sdr-sharp/overview) on how to receive images from NOAA satellites using SDR. This post will be about my experiences and ideas on how to improve the process I used. There are several items needed before having a finished image. These were the pieces used in my setup and some description about each. The first is the SDR hardware. Obviously this will be a requirement. It’s the typical DVB-T USB device most commonly used for SDR….

Cutting through the smoke with Retinex

September 7, 2018 Patrick Gilfeather

Standing on the shores at Shilshole, the smoke was so thick that land wasn’t visible across the Puget Sound. I wondered if land was still visible from a digital camera, even though I couldn’t see it. There is an imaging processing technique call Retinex that is used to enhance the dynamic…

RClone is the Rsync with the Cloud

August 7, 2018 Patrick Gilfeather

RClone is an extended feature set to rsync which provides a way to use cloud storage for file backups. To install it, refer to this link https://rclone.org/downloads/. In my example I run these commands to download and install RClone. wget https://downloads.rclone.org/v1.42/rclone-v1.42-linux-amd64.deb sudo dpkg –install rclone-v1.42-linux-amd64.deb Next is to configure RClone to use the cloud service. I ran this command to do that.
