AM25 •21These rules are published in 100 “Parts,” covering anything imaginableconcerning the topic of “Telecommunications.” The six books containing theFCC rules are section 47 of the complete Code of Federal Regulations,which you are likely to find in the reference section of your local PublicLibrary. If you have any legal questions concerning your AM25 or any homebuilt device which emits RF energy, it is your responsibility to study the FCCregulations. It is best if you personally read the rules (and consult with alawyer if you’re in doubt) and not bother understaffed and busy FCCemployees with questions that are clearly answered in the rules. A sign onthe 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 thecurrent FCC rules, as of May, 1990. This is only a brief look at the rules andshould not be construed to be the absolute complete legal interpretation!It is up to you to operate within the current Part 15 rules and RamseyElectronics, 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 allover the rights of a licensed broadcast operator. If your operation of theAM25 interferes with anyone’s use or enjoyment of an FCC licensedtransmission of any kind, your only choice is to immediately terminate orchange the operation of your low power transmitter.“On the Air” Etiquette1. Do not use “made up” call signs to identify your transmissions. Only theFCC has the authority to grant such callsigns. Use some other way toidentify your transmitting activity, such as “ This is radio 550, PittsfordSchool 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 yourtransmission. The FCC is toughest about clandestine transmission whichcosts 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 withbroadcast reception, stop or change your operation immediately.ANTENNA EXPERIMENTINGSince one wavelength (λ) at AM broadcast frequencies is over 950 feet, anda distance of only ten feet is allowed between the transmitter and antennatip, you may want to experiment with a “loaded” antenna for betterperformance.
