issued to amateurs who want to operate transmitting stations and these
are: (1) the _restricted amateur license_, (2) the _general amateur
license_, and (3) the _special amateur license_.

If you are going to set up a transmitter within five nautical miles of
any naval wireless station then you will have to get a _restricted
amateur license_ which limits the current you use to half a _kilowatt_
[Footnote: A _Kilowatt_ is 1,000 _watts_. There are 746 watts in a
horsepower.] and the wave length you send out to 200 _meters_. Should
you live outside of the five-mile range of a navy station then you can
get a general amateur license and this permits you to use a current of
1 kilowatt, but you are likewise limited to a wave length of 200
meters. But if you can show that you are doing some special kind of
wireless work and not using your sending station for the mere pleasure
you are getting out of it you may be able to get a _special amateur
license_ which gives you the right to send out wave lengths up to 375
meters.

When you are ready to apply for your license write to the _Radio
Inspector_ of whichever one of the following districts you live in:

First District..............Boston, Mass.
