NEWPOSS|B|L|T|ES
ARE SEEN IN RADIO
'TWo-Way AHpIane- to-Land
Experiments Open Up
Field of Fascination.

A new wrinkle in two-way radio
telephony from ground to airplane
, was demonstrated yesterday when DR..
George X. Burgess, director of the
Bureau of Standards. sitting before
an ordinary telephone in his Office
talked with w. B. Stout, head Of the
aircraft division of the Ford Motor
Co, who was in plane flying over
Washington.
Wireless conversations between
ground and plane are frequently car
ried on by Army and Navy expert
menters, but they use special field
sets for the purpose. DIR. Burgess
talk over a desk phone opens an angle
in radiophone possibilities that holds
new radio fascinations for the lay
man.
'PhOning Across Sea.
II the@ experiment develops wide
spread use, a person may speak from
his home or office telephone to another
riding in an airplane many miles
away, or he might be "rung up" from
the air by friend. With transat-
lantic telephony developed, it might
even be possible to call up some one
in London from a plane flying over
the United States, or vice versa.
Some of the projected New York

radior eceivers and transmitters,
whereby continual contact might be
maintained from shore TO the plane
as it rides above the sea. but code
messages alone could be transmitted
over the long range with the appa
ratus it is proposed to carry. If trans |
oceanic dirigible or airplane traffic is
developed, it is conceivable that con- |
stant telephone communication will |

WirIess Aerial Trolley.
There was special hookup between |
the Chesapeake and Potomac tele |
phone exchange and the Bureau of |
Standards experimental station just |
across the District border in Maryland |
for the conversation. Aside from its
novelty, the practical value of the
experiment to military and CONNER |
cial aviation is evident. The Bureau |
of Standards has already perfected the |
directive radio beacon, a wireless |
aerial trolley. serving to keep planes |
on their courses.
Such aids will make flights possible |
regardless of fog or darkness. In a |
multiple engined plane, properly equip |
ped, the safety factor would be about |
complete There could be no forced |
landing because of engine trouble, for |
there would be alternate relief power;
the plane could not get lost, Tor it
would have radio guidance. and no
other danger could approach without
warning. such as a storm. for the
plane would be in constant touch with
the ground by radiophone.
A concert composed entirely of /
selections from famous operas will be
ESA1I Tora
the outstanding attraction on the pro-
gram of WRC. The famous over
ture, "Tannhauser' of Wagner, 1.-The
Barcarolle," ;" from Tales of Hoffman:
excerpts from Faust" and 'Miserere,
from "Ill Trovatore," are some of the
featured numbers.
A recital by George Anderson, tenor,
is another of WRC's principal attrac-
tions. Mr.. Anderson will sing the
compositions of John Prindle Scott,
who will accompany him. Mr.. Scott's
works have won prizes from the State
of Nebra ska and Ohio University.
The weekly concert of the National
Concert Artists viii bring before the
the well known Frances
Paperte, mezzo soprano, who will pre-
sent a series of folk songs. Other fea-
lures on WRC's schedule include the
Lord Calvert Hour of Music. dinner
concert by the Raleigh Orchestra. and
tabloid version of current Broad
way production.
Dialing was decidedly tedious and
unproductive of se:sfactory results
last night. The wave lengths were un-
responsive. and reception necessarily
was restricted to limited number of
stations. Those few signals available
were even difficult to tune, and when
once found, static would not permit
them unobstructed passage.
The atmospherics crashed and crack
led steadily throughout the evening.
The signal strength of the stations
that We're tunable was fair. however
but it was utterly futile to attempt
TO listen amid the uproar. Only such
superpower stations as WGY and
WLW could be heard with any degree
OF satisfaction.
