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 />
