homebrew amateur radio astronomy gear

Postby john whitehead » Tue Jun 04, 2013 9:19 am

I'm having difficulty finding how to do things in this system, finding my way to inputting my text.

My problem; I have a new laptop Five weeks old. dropped the old one. the new one has win8 64bit, nothing else available. Now I find my software drivers want run. I did think this would be the case but there was nothing else on offer. Now I'm stuck. If you have a way around this for me I'd love to know. One thing is I use Two Gstar EX cameras these are both analogue out. I have to run a frame grabber between the cameras and the digital input of the laptop. This is only one of the many.

hi friends

hope im right here in this thread.

first, sorry about my bad english ;)

now my question to the Forum and theskynet-team:

i want start a Project to bild my own Radioteleskope...yes that sounds stupid but i have this idea now many years.
from time to time i search the Internet about News to build one self.
yes there are some interesting Projects.
some i dont like because they are to simple(with a satfinder) or on the otherside to expensive(microwavereciever and spectrumanalyser)
my way is try to find that between, that meas to build the most parts self, and here is where i stopped :( , dont find a nice detailed Manual to build the most of electronic parts self.
at this Point the Forum und thekynet maybe can help me.

my idea is to collect the Signal with a sateliteantenna, build a preamp, mixer, ifamp, a/d-converter and send the Signal to a pc to Show.
i also saw some nice usb-spectrumanalyser with different frequenzes, can this be in combination with sateliteantenna an Option?

hope you have some Manuals for me to get started.

Hi the chosen,

Thanks for your question! Unfortunately we don't have a manual to build your own radio telescope available.

We have some wonderful engineers who work at ICRAR who have helped us make two mini radio telescopes.
We purchased the electronic components from radio astronomy supplies ( - the filter and low-noise amplifier specifically.
We also purchased a satellite TV dish online that we repurposed.

We digitise the signal using a USRP ( ... Peripheral) - which then feeds the digital signal into some custom software that one of our astronomers wrote for us in Linux. You may be able to use something like 'iSpectrum' (on Mac) or similar which I have used before.

I'm sorry we're not much more help than that - good luck!

Hi Kirsten,

I would be interested to know what frequencies & radio phenomenon you are monitoring with the equipment you mentioned. Which filter frequency? Also, which model USRP?
