For this you will need:
RTL SDR USB software defined radio. It costs around 20 pounds.

I have discovered a problem with this radio. It does not pick up weather satellites at all any more but it still picks up everything else very well. It seems to lose sensitivity to the signals over time.
SDR Sharp. You can search Google for this.
this is a free program.
There are many places to get it
2 metre long piece of wire
long pole to hold the wire
A small laptop computer that you can hold for 15 minutes at a time.
You can connect your radio to a USB extension cable and just hold the radio in your hand rather than having a laptop under your arm. If you do this, the USB cable sometimes causes noise and signal loss so it is best to have the radio plugged directly into the laptop.

Step 1: The Setup
You simply have to secure the wire to the central pin of the coaxial connection by soldering or making up your own connection. The other end of the wire is attached to the other end of the pole a bit like a fishing rod. Once you have the software at the right frequency, you close the laptop, hold it in your left arm and hold the antenna pole with your right hand until you can hear the satellite.
To set up the software so it detects the radio, you need to copy rtlsdr.dll into the same directory as SDR Sharp.
A better guide will be included with your radio or you can find it online.
In SDR Sharp, you have to set the front end option to your software radio. In my case it is RTL SDR/RTL 2832U.
You have to uncheck filter audio and you must set the bandwidth to 36 KHz. The mode should be set to NFM and the squelch off.
I find that my radio picks up NOAA 18 the best so go here to track it:
It struggles with other satellites because there are noise spikes near the NOAA 19 and NOAA 15 frequencies. These spikes may be caused by the radio itself or USB power supply noise.
Step 2: Downloading the Images
Step 3: Decoding and Results
The ideal setup for this would be a roof mounted quadrifilar helix antenna connected to a proper satellite receiver or your software radio but this is the expensive option.
