Engineer,
MANY letters have been received
By W. A. Jacoby, indianapolis Times
radio interference engineer, from
residents along Central avenue in
the section between TWenty-sixth
and Thirty-fourth streets, asking re-
lief from the interference that COM
pletely covers the radio reception.
After a careful and complete
check was made Of this secion JacO-
by found that the major interior
ence was coming from the Indian
apolis street railway system. The
tracks along this section are IN
very poor condition. causing the cars
to swing back and forth. this action
sliding the wheels enough to make
poor contact on the grounding sys-
tenn which appears on the radio III
the form of popping and crack
ing sound.
In addition to this trouble the
rail bounding may be poor. allowing
all motor noises of passing cars to
be heard by the listener in this
area.
Blames Stop Sign.
The stop and 60 sign at Thirtieth
and Central is also IN very poor
condition and after a late hour
check when the air was free from
other interferences the noises made
BY the make and break contacts
when the lights change could be
heard some distance.
These cases of interference can
easily be cleared up and Will be re-
ported by Jacoby. who viii continue
10 check this district for additional
radio trouble so that the fans liv-
ing along Central avenue. may at
by the listener due to the fact that
least have fairly good reception.
Radio interference is noticed now
the summer months make the radio
stations harder to receive. When
z local interference breaks in. the
set naturally receives the stronger
of the two signals.
Praises Times Service.
That many indianapolis radio fans
are taking an active interest in the
Times radio interference depart
ment is evidenced by the letters
coming to The indianapolis Times
Office every day. An example of
the trend Of these letters is given
in the one printed below:
Dear Sir:
Am very pleased with the great
interest your paper is taking in the
troubles of the radio fans.
wish to take this opportunity
to especially thank your able inter
ference engineer for his fine work
in clearing the air of unnecessary
interference.
Have taken your paper for num-
Der of years and am perfectly salts
fed. I have never had any fault
to find with it.
Yours respectfully.

Arlington Fans Complain.
The section around Arlington ave-
nue. and East Washington street has
also been having a great deal Of in
reference in the last two weeks and
many letters have been received by
The Indianapolis Times radio inter
ference engineer from listeners in
this locality.
This section has several different
types Of interferences. but the major
one is, the stop and go sign that
has just recently been installed.
This make and break box is in good
condition but they all make inter
ference unless they are properly
equipped with r. F. chokes and con-
densers to take out the noises of
the change of lights.
Another interference that can he
heard some distance on the radio
Is the motor of the air pump at the
filling station. which needs new
brushes, etc.
It Is the belief of many of the
fans in this section that the street
railway Is causing the major portion
OF the trouble being received at
present but TO the contrary the sur
Vey proved that only a few of the
street cars and the freight cars
we're making the trouble. as this
section Is all new track.
