Experimenting with LoRa and MeshCore

Experimenting with LoRa and MeshCore I have experimented with Software Defined Radio and GNU Radio [1] before, but not that much with LoRa. LoRa is usually hidden inside a small radio module where you configure frequency, bandwidth and spreading factor, then let the chip handle everything else. That is convenient, but it also hides all the fun parts. I recently started to play with MeshCore [2], which is a small mesh network built on top of LoRa. cover

NOAA Weather satellites

NOAA Weather satellites Me and a friend started to talk about SDR (Software Defined Radio) and GNURadio [1], which reminds me of a old project I did for many years ago - reading out images from NOAA weather satellites using SDR, a QFH antenna and GNU Radio! I found some old pictures, but unfortunately, I do not remember the details as it was almost ten years ago. But I do know that we were using a HackRF [3] to catch the radio signals. cover
