I am an electronics engineer and I though a good project would be to build
an aircraft tranceiver.

You may not operate such a tranciever (even to test it) unless you and the
equipment are licensed. You won't get the equipment licensed without paying
mucho money. Amateur ("ham") radio operator can build and operate their own
equipment but only on the ham bands. That would be something to look into. Go
to http://www.arrl.com for information on how to get involved in ham radio and
get licensed.
