[SOLVED] Radio Telescope circuit or design

Hello everybody
I like electronics and Astronomy but i know more in electronics so I want to make a VLF Radio telescope or any Radio telescope but I dont have a circuit or a design for it so I want a radio telescope circuit and i want it simple ( if possible ) so if anyone has one please give it to me
And Thanks :?:

Hope these links help you forward....

Thanks kak111

Can someone give me another radio telesc:lolpe circuits these are very good but i want one more simpler

One radio telescope, capable to detect solar radio noise at 11 GHz is available from ELEXP. com as model RTL-11 portable radio telescope.

If you find it too expensive and want to make it yourself, let me know at "jpolivka@spaceklabs.com".

that last link in KAK111's post for a VLF receiver is about as simple as you can get and still have something that will give results

If on the other hand you dont want to build a receiver. You can do good experiments with a decent brand shortwave receiver (Yaesu, Kenwood or Icom brands) like us ham radio operators use and in the 20 MHz to 30MHz you will pick up Jupiter and solar flare noise. Even at 50 MHz I have had big solar flares totally full scale on the radio receiver.

Hello Dave:

May I ask you for your antenna details? Due to local interference I have been unable to detect solar noise below 3 GHz in California. Thanks!

hi Jiripolivka

on the HF bands 3 - 30 MHZ I just use an inverted V dipole

on 50MHz a 3 ele yagi ( note it wasnt pointing at the sun to get the big bursts of solar flare noise)

what sort of local noise do you have ? unless you are living beside a major industrial area, power generating station or EHV transmission lines
I couldnt believe background noise would be too bad

Dear Dave:

I was trying to detect and record solar noise over the UHF range as well as around 50 MHz with various antennas and receivers but the local TV and other interference caused that all attempts to record anything were bad. I could hear the solar noise but all records were only full of spikes without any reasonable solar noise visible.
I was so far only successful in recording solar and lunar noise with C-band and Ku-band satellite LNBs, and a 60x80 cm offset antenna at C-band; a 1-ft dish was OK. Even at C-band, a local interferer causes high spikes on the solar plot.

The interference is not only my problem; a group of Swiss astronomers run the CALLISTO program; they use a TV tuner as a spectrum analyzer; to record solar storm noise, they developed a clever software that maps local interference and then cancels it against the weaker solar noise.

I think in Australia the situation may be much better than anywhere else. Also my attempts to record SID signal at ~24 kHz mostly failed due to interference.
Thank you, Jiri

Dear All,
I want to understand how digital tuning engage in FM radio receiver and how it works.
I have the idea of how FM analog receiver works with variable cap and inductor resonnce cct.
Please advice me on this.

Thanks (Nuwan Mahesh)

start your own thread mate, its kinda rude to hijack some one elses thread

Dave

Dear davenn,

Thanks for your advice.
As I was new to hear I was not aware of how creating new thread.
As you requested I made a new thread.
Kindly help me on that thread.

Thanks.
