You can use the free online SUWS Web Software Defined Radio (WebSDR) from your PC or Laptop to receive the International Space Station (ISS) and the many amateur radio satellites transmitting in the 145.800 – 146.000 MHz band.
The SUWS WebSDR is located at Farnham not far from London, listen to it at http://websdr.suws.org.uk/
Martin says this about the special satellite antennas “I had been experimenting with single turn ‘twisted halo’ design, and decided to try stacking them to see if I could achieve more gain. Modelling suggested that a stretched 3 turn helix with a helix circumference of approx 1/2 wave length and an overall length of 1/2 wave at 70cm, and fed with a gamma match at the centre would offer reasonable gain, an omni-directional pattern and mixed polarisation.”

WebSDR for 144, 432, 1296 and 10368 MHz
