Anybody got a circuit diagram for a VHF AM covers 118-136MHz - I want to build one...

Has anyone got any good schematics or ideas ?


Since you want to build a transmitter on the aviation band, you have to meet
some pretty tight bandwidth requirements. The last thing the aviation
community needs is a unlicensed, possibly "dirty" transmitter on the aviation
band.

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.

That is not true. You can't get the license until you do the TA & C tests, and
you can't do the tests until you get the license? No, the FCC does not make us
do the chase-your-tail routine so common with the FAA.

BTW for both of you, it is "transceiver".

The rules allow a little latitude, much more than you realize. Mucho is in the
eye of the muchee.

That isn't true either.

You are telling an electronic engineer about ARRL? That's a kick.
