The

EK

1010

Mikroport receiver

is

a mini

-receiver

of the highest

quality. It is

of identical

mechanical

construction

to

the

SK

1010

and its

small size

enables it

to

be carried

unobtrusively,

for

example

in

a pocket

or

around

the neck with

the accom-

panying lanyard.

All

versions

are

fitted

with quartz

crystal

oscillators

and rugged

ceramic filters.

The

high

stability

of

the receiving

frequency

ensures

long

-term

reliable

operation.

The

power

supply is

obtained from

a conventional

9 V

6

F

22 battery

or a nickel

cadmium rechargeable

cell of the

same

type. It is not

necessary

to

remove

the

cell from

the

receiver

for recharging.

Recharging

contacts

on

the

housing permit

automatic

recharging

with the

aid

of the

SZL

1010

recharger.

A red

LED lights

up

to indicate

when

the receiver

is

switched

on.

The

battery

status is

displayed

by a green

LED

when

the

operating

mode

switch is in

centre

posi-

tion.

Headphones,

induction

coils

or extension

leads

can be

connected

to

the output

of the

EK

1010.

An

output voltage

of

2 mV

is available

as

a

fixed

level

at

the 8 -pin

socket, in

addition

to

which

the

low-

impedance

output in

the

same

socket

can

be adjusted

by

up to

approx. 2.5

V.

Similarly at the

output

socket

a bridge

enables the

fixed

electronic

squelch to

be deactivated.

The

EK

1010

wideband

model

has

3

switchable

receiving

channels from

the

30 to 45 MHz range.

The

widest

spacing

between

these channels

should

not

exceed 1.5

MHz.

Our range includes

the EK 1010

-R, which

is

the same

model

but

intended

for

the

frequencies

used

by West

German

broadcasting

stations.

For operation

in

the

40

kHz

frequency

raster the narrow

-band

model

EK 1010

-6

is

available

and also

covers

the

frequency

range

between

30

and 45 MHz.

Designed in

double

superhet

the unit

affords

single

channel working

only. 1 main

application

is in

radio

tour guide

systems

and for

assisting

the hard

of hearing (see

page

97). The EK 1010

-8 is

designed for

the

special requirements

of

wireless

pilot sound

trans-

mission.

The

EK 1010,

EK 1010

-R and

EK 1010

-6

receivers

include

a

headphone

as standard,

com-

prising

the HZS

1 -1,

HM

35 and HZL 18

-30.
