Radio Astronomy

Members of the group have been experimenting with Radio Astronomy in their backyards. From this page, you can view their experiments. We would also love to hear about your experiences - please contact us to let us know how you are observing the sky!

Itty Bitty Radio Telescope

The Itty Bitty Radio Telescope is made from a small second hand satellite dish and cheap components available from auction sites on the internet.

1m GHz Parabolic Dish Radio Telescope

Re-creating the Itty Bitty Radio Telescope, but this time using a 1m dish to increase sensitivity.

ICOM R7000 Receiver

The ICOM R7000 Receiver has been recommended by SETI for amateur SETI work. This is a high quality amateur radio receiver capable of covering a wide range of frequencies in AM, FM and SSB modes. Although not possessing AGC off functionality, a large number of mods have been published on the internet from amateurs for it. Unfortuanately, it is no longer available new but sometimes becomes available second hand.

ICOM IC PCR-1000 Receiver


The ICOM IC PCR-1000 offers an extremely wide range of frequencies to listen to - from virtually 0-2000 MHz, covering HF, VHF and UHF bands. It is also a small box which is easy to transport. This receiver is computer controlled. I obtained one of these second hand and hope to use it to observe Jupiter and also for other wavelengths - comparing its signal with the ICOM R7000.

UKRAA Very Low Frequency Receiver

The UKRAA Very Low Frequency (VLF) Receiver is designed to indirectly record Sudden Ionospheric Disturbances¬  (SIDs) induced by solar flares.

It does this by monitoring transmissions from Earth-based beacons, which are affected by changes in the ionosphere, giving an indication of events on the Sun.

The main motivation for this work is to correlate the radio observations of solar activity with those from optical observatories, and to follow the cycle of sunspots as they appear.
