Propagation

Forecast

Starting this issue

we have

made our prop-

agation forecasts even easier for shortwave

listeners to use. If you are DXing

at a

cer-

tain hour, simply run down the left -hand

column in the Forecast table

until you find

the

appropriate time slot, then

look

across

to

the right and determine

what

is available

on

which

bands for each major area in the

world. Bands in

brackets are promising sec-

ond

choices.

Time

intervals

are for your lo-

cal

standard time.

If you live in

the

Central

Standard Time (CST) zone then

the

Time

column

in our

Forecast table is

CST.

On the

other hand, if you

are

listening

for

one

particular part

of the

world only,

check

the Peak

DX Periods table first to see

what

time the best

DX is

available

from that area.

Follow this time slot across

in Forecast table

to determine the

best bands. If you live in

the CST zone,

use the

Eastern

column

but

deduct 1 hour.

To

use

the table put

your

finger

on the

region you

want to hear and log, move your

finger down

until

it

is

along

side the

local

standard

time at

which

you

will

be

listening and lift

your finger. Underneath

your

pointing

digit

will be the shortwave band or bands

that

will give the best DX results.

The time

in the above

propagation

prediction table

is given in standard

time

at

the listener's location

which effectively

compen-

sates for differences in

propagation characteristics between

the east and

west

coasts

of

North

America.

However, Asia and the South

Pacific

stations

will

generally

be received stronger

in

the West

while

Europe and

Africa

will

be easier

to tune on

the east coast.

The

shortwave

bands in brackets

are given

as second

choices.
