31 foreign

from Tagalog

(the

na-

tongue

of

the Philippines)

to

Swahili

and Hausa,

and in five

Chinese

dialects

(Mandarin,

Cantonese,

Amoy,

and Hakka)

Rapid Development.

Practically

all of

Radio

Peking's

broadcasting

develop-

ment

has

taken

place in the last

20

years.

When

the

Communists

took control

of

China in

1949, they

were able

to broad-

cast

only 56 hours

a week in

their

Inter-

national

Service. By 1959,

after

the So-

viet

Union

and East

Germany had helped

the

Chinese

set up manufacturing

plants

to produce

radio

equipment,

this

figure

had

increased

nearly

tenfold -to

512

hours

per week. In

the next

decade,

from

1959

to 1969,

the figure

increased

again

by more

than

tenfold.

The

Chinese

Communists

first

began

broadcasting

to the outside

world on

Sept.

5,

1944,

with the establishment

in

their headquarters

at Yenan,

Shensi

Province,

of the Hsin Hua

Kuang

Po

Tien T'ai

(New

China Radio Broadcast-

ing

Station)

.

This was, however,

a

rather

small

effort

since the station

operated

with only

a 300 -watt transmitter.

It was

not until 1953

that Radio Peking's

casting hours

began

to

rise

at a

marked-

ly

accelerated rate.

By 1957, Peking had started laying

out

several 120,000

-watt

short -wave

and

a

150,000

-watt

medium -wave

transmit-

ters. The

short -wave equipment could be

tuned

to one of 6 International Broad-

casting

bands. Audio -frequency response

was

50 to 8000

Hz,

plus or minus 1.5

dB.

Distortion in

the audio range of 100

to

5000 Hz

was

less

than 5 %,.

Since

that time, the

Chinese have man-

aged to produce

and put into operation

transmitters

with

power outputs

up

to

240,000

watts. The factories believed

to

be turning

out

this

equipment

include

the Peking

Radio Factory,

the Peking

Broadcasting

Equipment Factory

(both

in the

Chinese capital),

the

Nanking

Ra-

dio

Factory (in

the East

China

Province

of Kiangsu)

, and

the

Harbin

Radio Fac-

tory

(in

Heilungkiang Province

in Man-

churia) .

Broadcasting Patterns.

It is

generally

believed

that

Albania

-China's

only

true

and unwavering

supporter in

the

Com-

munist

camp -now

uses Chinese

-made

broadcasting

equipment. On

the other

side

of the coin, Albania

offers

a service

of

considerable

value to Peking's

short-

wave interests.

Some

of Radio Peking's

broadcasts to Europe, Africa,

and

both

the

East

and West Coasts

of

North Amer-

ica

are

relayed

from Chiak, near

Duraz-

zo,

which is

west

of

Tirana, the

capital

of

Albania.
