Back in the mid-1960's Novices could run phone (AM in those days)
on 145-147 MHz. The Heath Twoer was a cheap (for then) and simple
kit rig that was very popular. I and quite a few of my teenaged
friends got started on hamming this way. 2 meters may be too
crowded most places for that today, but it would sure be nice
if a cheap simple rig like this could recreate those times for
today's kids.

Lots and lots of regulations apply, and you can find them by going to your
school library and asking for the FCC regulations. Which part you want
depends on what sort of license you want (and you will need a license to
do this, indeed).
I recommend looking at the experimental service. Apply for an experimental
frequency somewhere between 50 and 500 MHz... the FCC will assign you a
frequency wherever they have space. I think that FCC Part 73 is the place
to look, but in the case of the experimental service you can basically do
anything anywhere if you can convince the FCC that it's important, and you
can't do anything at all unless you can. It's designed for stuff like
this.
Go to your local FCC field office and explain what you want. They will
give you the appropriate paperwork, and really tend to be quite helpful.
Expect about a year for the experimental license to get processed.

I'm working on a project which requires a signal to transmit about 100
ft. or so. All the sinal needs to be is a pulse or a steady tone in
which it will send a high output into my circuit which will then activate
a device of mine. If anyone could provide a scematic Digagram on how to
build on of these, I would appreciate this very much...Also if someone
cannot answer this, could refer me to a book which would cover projects
of a similar nature....Thanx,
