These rules are published in 100 "Parts," covering anything imaginable
concerning the topic of "Telecommunications." The six books containing the
FCC rules are section 47 of the complete Code of Federal Regulations,
which you are likely to find in the reference section of your local Public
Library. If you have any legal questions concerning your AM25 or any home
built device which emits RF energy, it is your responsibility to study the FCC
regulations. It is best if you personally read the rules (and consult with a
lawyer if you're in doubt) and not bother understaffed and busy FCC
employees with questions that are clearly answered in the rules. A sign on
the side of one of magician David Copperfield's tour trucks comes to mind -
"Only fools disturb sleeping tigers!"
Here are what we feel are the primary "do's and don'ts" picked from the
current FCC rules, as of May, 1990. This is only a brief look at the rules and
should not be construed to be the absolute complete legal interpretation!
It is up to you to operate within the current Part 15 rules and Ramsey
Electronics, Inc. cannot be held responsible for any violation thereof.
Licensed Broadcast stations and their listeners have all the rights! Your non-
licensed use of any device such as the AM25 has absolutely no rights at all
over the rights of a licensed broadcast operator. If your operation of the
AM25 interferes with anyone's use or enjoyment of an FCC licensed
transmission of any kind, your only choice is to immediately terminate or
change the operation of your low power transmitter.
"On the Air" Etiquette
1. Do not use "made up" call signs to identify your transmissions. Only the
FCC has the authority to grant such callsigns. Use some other way to
identify your transmitting activity, such as " This is radio 550, Pittsford
School Student Radio," and so forth.
2. Identify the location and purpose of your transmissions from time to time.
This is a common courtesy toward other persons who may hear your
transmission. The FCC is toughest about clandestine transmission which
costs time and money to track down.
3. If you are contacted by the FCC regarding the use of this device,
cooperate fully and promptly.
4. If you receive any complaint about your transmissions interfering with
broadcast reception, stop or change your operation immediately.

ANTENNA EXPERIMENTING

Since one wavelength (λ) at AM broadcast frequencies is over 950 feet, and
a distance of only ten feet is allowed between the transmitter and antenna
tip, you may want to experiment with a "loaded" antenna for better
performance.
