CANADIAN TRAINS MAKE LONG
DISTANCE RADIO RECORDS

The use Of radio sets on RAILROAD
trains is little more than a novelty
yet many surprising reception records
have been made. Passengers in the OBJ
servation car of Canadian National
transcontinental express, recently lis
tened to the strains of music broadcast
by Vera Cruz, Mexico, while their
train was laundering along at sixty
miles per hour near Edmonton, AL
berta. Prior to this, while passing
through Manitoba, they were RECALLED
with dance music direct from Mexico
City.
According to Roy Cummings, a
member Of the service engineering
staff of Cared Corporation, this is
but one example of the remarkable
distant reception possible on the nor
thern trains. Mr.. Cummings makes
periodical inspections of the installa-
tons maintained by the Canadian rail-
road.
Three years ago The Canadian Ma
tional, seeking to relieve the monotony
of long train journeys decided to equip
all of it's de luxe trains with radio.
The choice of a standard neutrodyne
receiver was made and the installation
begun. All of the sets are perma-
nently fitted into the observation cars,
and pair of ear phones placed on
each chair so that the broadcastiMg
could be plainly heard above the roar
of the train.
The installations have been com
pletely successful during the three
years of operation, and SO far as the
reception of distant stations is con-
cerned, they have exceeded expecta-
tions. This has proven very enter
tanning to the passengers because in
addition to receiving the latest news
and financial reports from Canadian
and American stations, they have been
able to enjoy the music of other coun-
tries. Experience has shown that in
reference is practically negligible
even when the weather varies rapidly
from falling snow to torrid heat.
Radio Noises on Photograph Records.
The earlier days of broadcasting
used to be bad enough when we had to
listen to the photograph over the ra-
dio. Now, Chicago man proposes to
listen to radio over the monograph.
His scheme is to record on a phono-
graph record all Of the possible noises
that may come from a radio set. The
record must also tell the name of each
noise and it's cause.
Thus, when receiver goes bad ard
sounds like a skeleton doing the
Charleston on tin roof-the listener
need only to put his radio-trouble
record on the monograph. He then
listens closely and picks out the noise
which sounds most like the ore coming
from his radio. The photograph record |
will then tell what causes that kind
Of noise and the listener can pro-

Time Signals Require Elaborate
System.
The reception of time signals from
The government radio station at Ar
ington for a re-broadcast on KDKA's
300 meter wave entails an elaborate
trapping and receiving system. The
set is located about a hun
lred feet from the transmitting sta
ion which has two sets of antennas-
or long and short waves.
In order to bring in station NAA on
he receiver which is so close to KID
AA's transmitter, a trap for each
wave band is installed before the re-
ewing set. Outside wires are sheath
ID in lead cable, and the apparatus
hielded by metallic screens. A metal
overed cable carries the signals to
transmitter.
