Main Question or Discussion Point

Hello,

I'm send to message in TURKEY. I'm 15 years old and I deal radio astronomy.

I have got a GyratorIIVLFReceiver and 75 cm VLF loop antenne. I can listen lightning and electronic tools. But I want to listen space. How to listen space? or Can I listen space?

Greetings from TURKEY!

Hi Ogulcan,
greetings from Australia, welcome to the forum :)

radio astronomy a wonderful subject. I wonder if you have heard whistlers with your VLF receiver ? ~ 15kHz was the frequency, I used a very large multi-turn coil of cable, something I used to enjoy when I lived out in the country away from big towns and cities with all their radio noise. The main problem was the 60Hz hum from the mains electric power supplies.
A good time to consider getting deeper into radio astronomy with the next solar max on the way (even if its going to be a smaller than usual one). Just about any receiver from ~ 20 MHz to 50MHz is good for receiving Solar Flares. I regularly would hear the flares on our 50MHz amateur radio band.

Jupiter is a good source of radio noise ... the 18 - 22MHz seems to be around the peak tho it does spread a bit more than that.

Those are a couple of examples that can be done with a basic and relatively cheap home system.
To get signals from deep space, say pulsars, requires a more substantial investment in dish antenna low noise receiver, technical knowledge etc etc, not for the beginner, but something to aim for as you grow in your experience :)

do some searching on google ... there's masses of info, look in your local library ( if you havent already) and keep coming back to PF and tell us all about your experiments and post your questions and see if any of us can help you out :)

this site has some good info.... http://www.radiosky.com/

Thank you for your reply. I know it all. I want to ask principal can I get with VLF signal from space?

well if you know it all already, why are you wasting our time asking !! ?? :(

Sorry, you false understand.

I know frequency. But I don't know can I get with VLF signal from space? So Can 3-30 kHz frequency comes world from space? İnşallah you can understand my English. :)

No, as far as I'm aware, you will only receive VLF signals from the near earth region
The ground (earthquakes), atmosphere and earth's magnetic field.
Anything outside of that and refer to my comments and frequencies above

Thank you for your reply. I understand but I've heard of something like this for example, the sun makes the publication of each band. Is this information incorrect?

The sun is an extremely broadband RF emitter. But I think you will find most of the good stuff is higher in freq say 10MHz - 50 MHz

Okey. Thank you for all reply. I hope over time I will learn everything. I wish you succes in Astronomy. See you later.
