Help on homebrewing
I just got the ham operating license in my country,
and I would like to start building my own homebrew equipment.
But I don't know how to start, maybe I need a little push. I know
that there is lot of info on the net, but I prefer to get help directly from the experts.
Thanks in advance, Ernesto.

The amateur radio organizations of the UK (RSGB) and US (ARRL) publish books on simple and complex projects.
Good for you! I can not encourage you enough to go build some equipment and learn how it works. With a 1 watt transmitter and a morse key you can communicate around the world! But more importantly, you will learn a bunch about electronics.
It is a little discouraging to walk into a HAM store and find that it has turned into the local version of a Best Buy store--you buy the gear and hook an antenna to it, and never ever figure out what is inside. If all you wanted to do was to talk to people, you could get a cell phone and a phone book and start to randomly call people!
This book has many simple projects to start with:

Every station is starting from receiver. Beginner need receiver to begin listen to short wave, advanced constructor need control receiver to make transmitter. Seems it is common point to start. You can make very simple Direct Convert receiver if you are beginner in electronics, or more complicated 2-3 conversion super-heterodine receiver if you are advanced constructor.
Seems you are at the very beginning. I think Direct Conversion receiver is nice point to start.
There is very good book about DC receivers, but for big pitty it is on Russian language. It was written by Vladimir Polyakov at 1981, it is available here:
http://hamradio.online.ru/ftp/1-70.djvu . Even if you do not know Russian , go to page 56 and you will see very simple SSB receiver with nice parameters (sensetivity near 0,5 uV, dinamical range near 70 dB) . It is on 28 meters band, but you can simply change band by L and C changing.
Next, look to this archive, you will find a lot of articles about HAM equipment in English:

There are good libraries about HAM constructions (in Russian):
