With all the neat things made for the amateur in the past say 40yrs any home radio telescopes?
Or a conversion kit for those 6-10ft vintage satellite TV dishes?
That is actually what got me wondering is the big old dishes I see in peoples yards obviously unused and could possibly be hauled away for a pittance.
Naturally though my brain is tuned to vintage/classic information first and foremost, simpler, and a better chance of something out there that needs to be fixed to work again, which is what I like to do.
Radio astronomy frequency waves are long compared to light waves which are short. This will require a fairly large telescope to be of any use I suppose. And converting the electrical signal to visual is probably not possible for the average amateur. Thats OK an oscilloscope tube is OK, or headphones?
Anyone have any thoughts like mine?
There must have been something made in the 60's surely.

neat, there is even an radio telescope society now.

Lots of stuff to look over. The Haystack SRT kit looks like just what I need.
The old obsolete dishes I see around sort of sparked my interest again but it just so happens I have a Hallicrafters Shortwave.
This is crazy, I have more than enough hobbies to keep me busy for the rest of my life. I don't even have enough time for work!
I must work though I need money for my hobbies!
Oh what a vicious circle!
Astronomy is my number one hobby, and radio astronomy will work through the clouds.
I have lots of clouds, fog and unstable atmosphere here in Washington state and in the Snoqualmie valley.

It just occurred to me that if it was really interesting wouldn't more amateurs be doing it?
I think I'm missing something important.

If you follow the links you can find some pretty interesting DIY units and plans. The SETI group has a lot of hardware too.
The old Sat dishs are good for the hydrogen line and higher frequencies. I have one and am slowly working on a small syatem- 3M dish, LNA kit and Icom 7000 reciever.
Lower resolution and sensitivity than you are used to with our optical scope, but interesting none the less.
