The Richmond palladium and sun-telegram. [volume] (Richmond, Ind.) 1907-1939, 1922-06-13

Summer static conditions, or "at-l
mospheric disturbances" as the new
er technicians call 1t, in full force dur
ing this season, has materially les
sened wireless activity and has almost
destroyed the enjoyment of novices
in listening to wireless broadcasts.
Many amateurs have shut down for
the summer. or are taking advantage
of the lull to repair and improve their
stations.
This season also is the 'open sea-
son" for hunting static eliminators, /
and many amateurs are on the trail. |
Use of an inside aerial or a coil aer-
ial is the first and easiest course. but /
many also are making use of ground I
antenna This is a long, insulated
wire in a shallow trench or even on
the surface of the ground. The i
ground wire should run in the direc-
| ton of the station to which the sta
ton is listening and should prefer
! ably be several hundred feet long.
| Novices will do well to remember
that the longer their antenna and the
more wires in 1t, the greater will be
| their trouble with atmospheric dis
/
will not give as loud signals as the
usual antenna, but may be more sat
isfactory for summer use through the
J elimination or lessening of static.
Eaton Amateurs
The Chicago Westinghouse station
! is being heard regularly by Willard
Overholser, of Eaton, with his two
stage barometer set This is sta
/ ton not always received in this sec
ton. Overholser also is getting long
wave stations up to 5000 meters.
Reception of Newark, N. j., over a
one-tube simple circuit set is reported
/ by Martin and Marvin Penland.
| Stations of H. Riley Splitter and
Orval Denlinger were tuned in and
listened to the race results at the In
dianapolis Speedway, to the enjoy
ment of numerous radio and auto fans
of Eaton For the benefit of the big
crowd that gathered. Mr.. Denlinger
used four stages of amplification.
Wireless Theatre Music
/ A theatre in Des Moines, Iowa, Is be-
ing equipped to receive wireless music
for the benefit Of it's audiences, the
broadcasts from Denver, Chicago and
Pittsburgh being relied upon. 1t is
suggested that musicians unions may
object as did the actors union, to such
use of music for which the perform
ers can receive no pay. This method
| will give as good music as IS usually
found in small movie house, but
there may be some difficulty in fitting
the music to the scenes, getting jazz
in death scene, for instance. A the
atre in Shelbyville, Ind, has followed
this example, also.
Train Message Service
Communication, not only between
trains and stations, but between trains
is the subject of experiments on the
Big Four railroad now. A steward on
the limited running between Cleveland
and Cincinnati has equipped his train
with a listening set and allows the
passengers to listen in on radio broad
casts Another train is being equipped
with sending set and will communi-
cate with the other while both are on
! their run.
The listening installation Is making
use of rectangular antenna stretched
around the roof of the car and about a
foot above ii. It Is about so feet in
length and three feet wide.
Novel Receiving Set
An annual receiving set has been ex-
hibited at recent radio shows, in the
shape of a parlor lamp, with a loud
speaking horn for a base, and the in
struments composing the set, hidden
by the shade.
Radio For Convalescents
]. H. Harrison, of Eldorado, is au-
thority for the information that Gin
cinnati hospital is installing four wire
less receiving sets for It's patients
, Wires will be run along the walls and
patients may plug in as they desire
Loud speakers can not be used because
, of the annoyance to some of the nerv-
GUS cases.
Ring Up On Radio
A device for calling up any station
desired by radio, without its being
necessary for the operator of that sta
ton to be "on," is announced by a
French inventor, l. Chaveau This in
vention makes use of the magnetic re-
lay, just as is used in controlling au-
to sand boats by radio. The relay at
] the listening station is set to be oper-
: ated by the call for that station. Any
station wishing to call has only to send
out the proper call, the last dot or dash
closing the relay and operating a sig
mailing circuit, which may ring a bell
