AMATEUR RADIO AND<br />
PUBLIC SERVICE<br />
The Amateur Radio Service was created as<br />
a public service. look no further than<br />
the first tenet of the Basis <strong>and</strong> Purpose 01<br />
the Amateur Radio Service in Part 97 , 10<br />
see this:<br />
(a) Recognition <strong>and</strong>enhancement ofthe value<br />
ofthe amateur service to the public as a voluntary<br />
noncommercial communications service,<br />
particularly with respect to providing emergency<br />
communications.<br />
A newcomer luning around on the amateur<br />
b<strong>and</strong>s. however, probably senses anything<br />
bu t bien public there. He hears pile-ups cotting<br />
the 15- <strong>and</strong> 20-meter b<strong>and</strong>s. Wh ile tuning<br />
around the 40- or eo-meter b<strong>and</strong>s, he runs<br />
across hams chalting amiably about the<br />
weather, new equipment, equipment modifications.<br />
<strong>and</strong> other similarly low-key topics. He<br />
also finds this rag-chewing on the z-meter.<br />
22Q.MHz, <strong>and</strong> 44D-MHz b<strong>and</strong>s. He soon discovers<br />
nets where members meel to pursue<br />
common interests-such as Irading information<br />
about equipment from a particular manutacturer,<br />
playing chess, or reminisci ng about<br />
common war-time experiences. (I once came<br />
across a gr<strong>and</strong>father clock net where the<br />
members recognized each other by the sound<br />
01 their clocks' chimes')<br />
He may conclude from all of this thai amateur<br />
radio caters only its own interests <strong>and</strong> is<br />
unprepared lor future emergencies-a service<br />
straying from its premier FCC m<strong>and</strong>ate.<br />
How wrong he would be! The ccnomcns outlined<br />
below show why amateur radio is the<br />
world's finest <strong>and</strong> most reliable emergency<br />
communications system.<br />
Marriage of Self-Interest <strong>and</strong><br />
Public Service<br />
Many nets meet with the intent to rehearse<br />
emergency communications. The conduct of<br />
almost all nets, however, contributes to ttns<br />
end.<br />
Traffic nets <strong>and</strong> OX nets are two of the mos t<br />
common kinds of ham nets. CW as well as<br />
voice nels are very popular. Members of tratnc<br />
nets relay radiograms. which anyone',<br />
ham or no, may originate <strong>and</strong> receive. One<br />
ham relays a message to the next, until it<br />
reaches its destination. People who have<br />
played the " rumor" circle game as kids may<br />
recall how information tends to distort as<br />
it passes from person to person . Traffic<br />
nets have developed a strict procedure to minimize<br />
this distortion.<br />
DX nets meet to provide hams an opportunity<br />
to contact other hams in rare countnes.<br />
These nets need tight contrelto maximize the<br />
number of stations contacting the rare station.<br />
lf the situation is left uncontrolled. the hapless<br />
rare station spends more time trying to get<br />
Dxers to quiet down than actually contacting<br />
them!<br />

The skills hams develop in these pursuitsmessage<br />
h<strong>and</strong>ling <strong>and</strong> net con trol-are vital<br />
to the smooth operation 01 emergency communications.<br />
Resilient <strong>and</strong> Fair<br />
Besides retaini ng the largest pool 01skilled<br />
volunteers, the Amateur radio service provides<br />
the most enduring communications in<br />
regions ravaged by natural disasters for these<br />
reasons:<br />
-s vstem portability <strong>and</strong> compactness<br />
- Sett-comameo power supply<br />
eRequirement of knowledge of CW<br />
- Volunteer-only tenet of the Amateur Radio<br />
Service.<br />
There are transceivers available now that,<br />
weighing less than ten pounds, powered for a<br />
number of hours from a car battery. <strong>and</strong> requiring<br />
only a d ipole antenna a lew dozen feet<br />
above the ground, alford reliable long-distance<br />
communications. Such self-contained<br />
systems let amateur communications remain<br />
intact when a natural disaster such as a hurricane<br />
or earthquake stri kes an area <strong>and</strong><br />
knocks out telephone lines <strong>and</strong> public service<br />
electricily.<br />
CW <strong>and</strong> voice are the two most common<br />
communication modes. CW-this much-maligned<br />
mode- is the more reli able of the two<br />
during poor conditions. This is because CW<br />
conveys information using only three distinc t<br />
elements-the "dit" (short tone). the " dah"<br />
(long tone), <strong>and</strong> the "space" (no tone)-which<br />
st<strong>and</strong> out in greater contrast to the ambient<br />
noise than do the many amplitudes <strong>and</strong> frequencies<br />
that voice uses to compose intelligence.<br />
Since most countries slitl require aspi-<br />
rants to learn CW to get any sort 01 amateur<br />
license, amate ur radio service world-wide retains<br />
the largest pool of CW operators 01 any<br />
communication service.<br />
One must not discount the non-remunerative<br />
nature of ham radio . Those who do have<br />
forgotten thei r horror at the callousness of<br />
nurses striki ng solely for pay, or that of a hospital<br />
that refuses to treat seriously ill patients<br />
who can 't pay for their treatment! Amateur<br />
radio's non-pecuniary na ture deters preferential<br />
treatment.<br />
This policy, ho wever, has not deterred<br />
hams' Willingness to assist in emergencies.<br />
There are innumerable accounts-the most<br />
recent are the vital role hams played m emergency<br />
communications during th e 19 76<br />
Guatemalan earthquake , <strong>and</strong>. documented in<br />
this issue, the Salvadoran earthquake 01OCtober<br />
1966. A lew of the many snuaucos are<br />
doctors thous<strong>and</strong>s 01 miles away tatking their<br />
inexperienced colleagues through an operation;<br />
summoning medical supplies: locating<br />
loundering ships at sea : finding lost campers:<br />
<strong>and</strong> directing rescue operations lor people<br />
caught in floods, blizzards, earthquakes, hurricanes,<br />
a nd tornadoes . Jerrold Swank<br />
W8HXR in his book The Magic of Ham Radio<br />
lists 65 pages 01 the most spectacular rescue<br />
operations our service has assisted':<br />
The Amateur Radio Service is a great latent<br />
strength. You hopefully will never need proof<br />
of this, but rest ass ured we're there for <strong>you</strong>!fl<br />

GLOSSARY<br />
Ampl itude-The strength of asignal. CW uses only maximum strength or no strength. The<br />
amplitude of a voice-modulated signal constantly varies.<br />
B<strong>and</strong> - A segment of the radio-frequency spectrum.<br />
CW - Synonymous with Morse code.<br />
Dipole - A simple <strong>and</strong> effective antenna popular wilh hams due 10 its easy <strong>and</strong> fast<br />
assembly.<br />
OX - " Long-d istance."<br />
FCC - Acronym for " Federal Communications Commission." This is the US government<br />
agency responsible lor the allocation of frequencies for radiocommunications <strong>and</strong> broadcasting<br />
in the US.<br />
Frequency - As a radio wave travels through space , its amplitude varies with wave-like<br />
peaks<strong>and</strong> troughs. The frequency 01 a wave, denoted in Hertz (Hz), is the number 01 peaks<br />
that pass a l ixed point in space in one second.<br />
Part 97 - The section of the FCC Rules <strong>and</strong> Regulations that deal specifically with the<br />
Amateur Radio Service.<br />
Pile-up - A collection of many stations tuned to the same frequency. Simultaneous<br />
transmissions cause confusion due to mutual interference. This often occurs when many<br />
hams try to contact a rare station.<br />
Radiogram - A telegram which the Amateur Radio Service (ARS) is authorized to send,<br />
free of charge.<br />
Rag-chew - Casually discuss.<br />
Transceiver - A radio station capable of both receiving <strong>and</strong> transmitting.<br />
Voice - Mode in which the human voce modulates a radio wave.<br />
