I have aquired 2 x COMTECH EF DATA SDR-54A units from a large investment bank that are closing a data centre. I would like to sell these units and give all the proceeds to The Childrens Society Charity.

There is a book "Radio Astronomy for Amateurs" (I think by Frank Hyde), published by the RSGB (Radio Society of Great Britain) which gives some low-cost ways of doing radio astronomy at home. Most involve using VHF and UHF rather than microwave. Jupiter is a good source of radio emissions as it turns out!

A good telescope shop should be able to get the book for you, or maybe Amazon.uk (I did a quick search but didnt find it).

Hi,
In order to use the PC to analyse the spectrum in this way you would need to spend a lot of money on the PC card to get a good quality spectrum analyser.
 
Next you will need a large antenna to get the gain required to be able to 'hear' anything from out in space. The receiver will need to be cooled, usually by liquid nitrogen, to ensure that the thermal noise is as low as possible. The chances of doing all this with a TV dish antenna and a PC with a suitable card are therefore slim.
 
If you can get the spectrum analyser PC part sorted out then you could use the TV dish antenna to view the signals that it receives but this is just not suitable for Radio Astronomy. The signals from far off distant stars are so small when received here on earth that you need the extremely large antenna described above in order to see anything above the background radiation and noise.

Hi.
(Sorry if my english is bad!)
I want to use a simple TV dish antenna to listen the sky.
I would like to know if a PC card could exploiting those antennas to chose the
listened Frequency with a wanted bandwidth and record the signal at this frequency.
I would like to know if I can analyse the spectrum with a dish antenna.

Thank you for your help, I don't know because I'm not student in electronics.

Unfortuneately, there seems to be a problem with the email address for Dan so notifications of these posts are not getting through.
