Dan Ritter of Allentown, PA is one

our

readers

who recently wrote. Dan

asks:

"Do

you have a a circuit

for

beat -

frequency oscillator (BFO) that I can

hook up to a portable receiver? Then I

could listen to the many

(code) and

SSB (single

sideband)

signals that my

receiver

can pick

up."

Hey, Dan, I have a pact with other

Hands -on Electronics

authors: I don't

"do" construction projects and they

don't deal

with

shortwave topics. Se-

riously, though, I have

doubts as to

whether

the results of any such project

would

worth

the effort. In the long

run, you'd

be more

successful

in tuning

CW and

single

-sideband signals (par-

ticularly the latter)

with

a receiver de-

signed to easily receive SSB. That

includes

some not -too- costly models.

But, if

you do

want

play

about

with

SSB,

you might try this

old trick -

sometimes

called the Poor Man's

BFO -that dates back to the early days

of single -sideband radio: Take a small

AM radio, place it near your shortwave

receiver. Turn it on but keep the

volume

as low as you can. No guarantees, but

sometimes

the

RF radiated by

the

radio will mix with

the SSB

signal and make those transmissions

intelligible.

Usually, the focus in this column is

on SW roadcast -i.e., music, enter-

tainment, news, and other programs for

general audiences. But

there are

other

transmissions

on shortwave, including

the non -program "utilities" such as

VOLMET- aircraft weather transmis-

sions for international flights.

Canada-6030 kHz. CFVP

Calg-

ary, Alberta is perhaps the toughest of

the private Canadian SW station to log.

But some DXers in the "Great

White

North" have heard it around 2100 UTC,

identifying itself as AM 106, after the

medium

-wave outlet on 1060 kHz that

relays.

Galapagos

Islands -4810 kHz.

Six

-hundred miles off the

coast of Ec-

uador, is that land of exotic

flora and

fauna,

which

challenged and

inspired

Charles

Darwin in the

19th Century.

Today that

lovely island is

home to the

shortwave

station, La

Voz

de Galap-

agos, also

announcing as

Radiodifu-

sora

de Galapagos.

That

station,

which

broadcasts

Spanish,

often can be

heard until its sign -off, at

about 0200

UTC.

Greece -9395

kHz. If you liked

the

music in "Zorba the Greek,"

chances

are you'll enjoy

tuning in to the Voice of

Greece,

which can be

found on that

frequency. Try looking at

about 0130

UTC.

Guatemala

-3380 kHz.

Like listen-

ing to Central

-American music

such as

Marimba

rhythms? Try tuning

Radio

Chortis

during the evening

hours. The

station signs

off the air just prior

0300 UTC.

Nicaragua-6100

kHz.

What

is the

Sandinistas government

in that country

saying about US policy?

You can find

out by tuning in Managua's

official sta-

tion, the

Voice

Nicaragua, in En-

glish,

at 0300

UTC.

North Africa -12,005

kHz. One of

the lesser -known and

seldom -heard

North African stations is

Tunisia RTVT,

which has been reported

with Arabic

programming, but European music at

around

0730

UTC.

South Korea -9570 kHz.

With

the

summer

Olympics

nearly upon us,

good spot to

watch

for

shortwave

coverage of the

competition is Radio

Korea,

Seoul.

English -language pro-

gramming can be hard between 1400

and 1500 UTC.

United States

-17,830 kHz.

WHRI, World Harvest Radio, transmit-

ting from Indiana, is one of

the new

batch of shortwave

broadcasters

with

religious programming that have gone

on the air in the

last several years. If you

are interested in the station,

you

can

tune it in at 2100 UTC.
