SWL.

What

is the

best an-

tenna setup

for

10 -160

meters?

-M. B., Toronto,

Ontario

Start

out

with

a 50 -foot wire

antenna.

Allied

Radio in

Chicago

offers

a

complete antenna kit

for 98

cents.

You

should

be able to

get one in

Toronto

for

not

much

more. Later,

as you get

more

experience,

and

if you

have

adequate

space,

you

can

use something

more

exotic.

Diode

can't

find

a

TD

-1 tunnel

diode for use

in

the

TD

-FM

radio

described

in a recent

issue. What

other

type

can I

use?

-L.

A. R., Detroit, Mich.

Get

a GE

IN3712. It

sells for $3.75.

Don't,

If

You Don't

Know

1 have 3- phase,

3 -wire, 220 -volt

power.

I

have

a machine

which

operates

from

a 220 -volt,

2-

wire

circuit

and ground.

Can 1 connect

it to two

wires

of the

three

-phase

circuit and

run

a

ground

to the

water

main?

-W.

O.

S., Niles, Mich.

If the

ground

lead

is used

only for grounding

the frame

of the

machine

and

is not actually

connected

to the

220 -volt

line,

OK.

Otherwise,

you

may need

a

star- to -wye

transformer.

Before

you do

anything,

consult

the power company.
