I have been slowly working on a new project.
I have been getting parts together to build my own.
Radio telescope!
Sounds like it would be a bit of a daunting task.
But now days? It is not that hard.
With the advent of SDR “Software-defined radio”
“Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system.[1] While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which were once only theoretically possible.”

Some one with even a modest amount of computer savvy.
And a small interest in Radio astronomy.
With a small budget and a few parts. Can build one in a week end.
Easy!
what you need?
A SDR. I am using a RTL-SDR dongel.

A computer with the right software.
I am using. Airspy SDR# (SDRSharp) revision 1811 software.
You can get this free.
Most SDR software is free BTW.
And something to use as a antenna.
This is where it can become a nightmare if you over think it.
I am going for a variation on a simple dipole antenna.
Using 2 slinkeys. and some coax to connect it with.

Very simple but very affective. Where I am limited on space.
It will work fine. It is a variation on the coaxial dipole antenna.
If it works only half as good as I hope? This will be fun.
Will be posting my findings here.
You ideas and input are appreciated.
A screen shot
Still learning


Found 5 pulsars confirmed so far. And one more I am not 100% about.
I just ordered a in line low noise amplifier. All so a in line FM filter.
We will se how well they work.
All so looking at a “Low Noise Amplifier Radio Astronomy Hydrogen Line Filtered 1420 MHz” But not yet. Don’t have the money for that.
Doing every thing out of pocket slows it down a lot.
Lets make that 6 pulsars so far. Found another last night.
Working on what I think is another!
getting better and better at this.
