Weather Images

Well, I've picked up trying to decode the NOAA weather satellites and later I'll move onto doing the new Meteour Satellites (this is a pick more complicated)
I started with the RDL-SDR.

I didn't have much success with my Turnstile Antenna, so I have started building a Double Cross Antenna (DCA)

I've been putting my pictures on my qsl.net web page:

Requirements and Setup

To set up a NOAA weather satellite receive station you will need:

1. An RTL-SDR dongle working with SDRSharp. (Or other more advanced SDRs such an Airspy)
2. An audio piping method (e.g. VBCable, Virtual Audio Cable or Stereo Mix)
3. A right hand circularly polarized antenna tuned to 137 MHz.
4. Software such as WXtoImg for decoding the APT signal.
5. An LNA (Optional).

NOAA Weather Satellite Antennas

The NOAA APT weather satellites broadcast their signal at about 137 MHz, and their signals are also right hand circularly polarized (RHCP), which means you will need a right hand circularly polarized antenna to properly receive the signals. Satellite antennas are also designed to receive best from signals coming from the sky. Three options for easy home made circularly polarized satellite antennas are presented below.
