somebody can point me to a contruction project, a kit or a source of a
VFO.


Buying a copy of "Experimental Methods in RF Design" (the successor
text to "Solid-State Design for the Radio Amateur") would be a very
good place to start reading. These guys have written down a vast
amount of very practical information and experience about how to do
this sort of thing well and reliably.

http://www.bright.net/~kanga/kanga/KK7B/uvfo.htm is a "universal" VFO
kit which you might be able to adapt for your needs.

Doug Demaw W1FB had another "universal VFO" design in his "QRP
Notebook" (a great book if you can find a copy). You can buy a kit
for it (board, semiconductors, air-variable cap, copy of the
construction article) for $30 from

I've bought stuff from Dan a couple of times and have always been
satisfied with what I've received.
