Receiving NOAA APT Weather Maps

After building a satellite antenna, I was able to receive and decode the weather maps sent by three US-based legacy satellites operated by the National Oceanic and Atmospheric Administration (NOAA). Hardware As mentioned, I used my own antenna. To get the signal into my PC, I used the excellent and low-cost RTL-SDR stick V3 by…

Building a Weather Satellite Antenna

During my adventures with SDR (software-defined radio), the need for a proper QFH antenna arose. This type of antenna is used to receive signals that are circularly polarized, such as APT weather maps sent by the NOAA satellites. I used a PVC pipe and a standard shielded coax cable from the local hardware store, and…
