RADIO TROUBLE
TRACED TO CITY
TROLLEY LINES
Much Interference Found
Due to Street Cars by
Times Survey.
Radio

Several serious cases Of radio in
reference have been checked to city
street cars by The Times radio in
Inference man in his survey OF the
last four days.
Conditions are growing worse,
making trouble for an increasing
number of listeners-in.
Nearly all the radio owners COM
planning use AC line current, and
this line runs along car tracks or
crosses them at different points.
Most sets are using 100 volts on the
last power stage and that steps up
all interference twice as loud as 1t
was when ninety was being used on
the last stage of audio.
Getting in Worse Shape
Now, according to the survey, the
car lines are getting in worse shape,
with trolleys flaJ-Sided, and rails
with gaps, making bad grounds. All
this makes broadcast even louder
than the local stations.
The interference man found Mon
day night, with his set at Twentieth
and College, that the cars cut out
WFBM and WKBF early. And just
wait till the ice gets on the wires
and rails, he warns, when the car
line broadcasting will extend for six
blocks in every direction.
The results of some Of the sur
vevs will be given in detail in to-
morrow'S story.
Here is an appeal for help from
Curtis G. Springer, 1924 Olney ST,
amateur GEAR, and others, that
will be given prompt and thorough
attention:
"Radio Editor Times: I have read
of the work your department has
been doing lately in clearing up
cases OF radio interference. This
is a noble undertaking, and no
doubt you will gain more friends
and supporters wherever radio
owner is benefited through the &C
tivity of your interference COM
mittee.
"since Friday night, Sept. 81, the
radio receivers within a radius OF at
least three blocks of Thirteenth
and Olney SITS, have been practically
useless, due to a steady 6O-cycle
buzz. which blankets reception on
all wave lengths between II and $50
meters, with no noticeable peaks.
ut is usually very steady, but oc-
casionally becomes intermittent
cutting out at irregular intervals
for a few seconds. Early Thursday
morning, Sept. 81, it had stopped
completely, but started again some
time during the day. 1t continued
until Saturday, Sept. %, when 1t
stopped until Sunday morning, but
has started again.
"If your interference committee
can rectify this situation, radio own
ers in at least fifty homes Will
greatly appreciate your cooperation"

was a plea from a number OF radio
owners, as follows:
