how to build pc based spectrum analyzers

Hi to all,
i need to build a simple RF Spectrum Analyzer using an Oscilloscope or a TV.
Anyone have a good project?

Here is a well designed SA but not so simple:

rf spectrum analyzer

thank you.
I have read that you have build it, it is easy to build?
The material are easy to find?

rf old project

Well, assembling is not difficult but tunning and adjusting can be. It depends. Here in Slovenia where the project originates the supply of critical components was organized. The project is now 9 years old.

Well, if the project is old 9 years it is easy to find components.
There are not new critical component.
Now i read articles and I estimate from I make myself

how to make a spectrumanalyzer

Problems may be in obtaining HP MMICs and HEMPTs. A 10.7MHz crystals for IF filter must be without parasitic resonances such as used in commercial crystal filters. Oscillator crystals are not suitable. Other semiconductors are standard ones and easily obtainable. PCBs were sold by VHF Communications and brass boxes (there are a plenty of them) you can still get from Slovenia.

Just to encourage you, here are PCBs for RF part in case you want to make it yourselfs:
it is TOP-view

Hi, many thanks
In effect for HP MMICs and HEMPTs the problems can rise. I can buy from rs or other international seller
