A busy season of experimental
broadcasting: on both long: and short
waves is to be conducted this Winter,
beginning: within the next few weeks,
by the General Electric Co., accord
ing: to plans announced yesterday.
Fifteen licenses authorizing: the use
of a variety of wave lengths from 3
to 379.5 meters have been assigned to
the General Electric stations and per
mission granted to conduct experi
ments at any power desired and at
almost any frequency.
YVave Length Selection.
Tt is expected that through the use
of one or more of the wave lengths, a
medium will be found that will pro
vide comparatively consistent trans
mission of broadcast programs to all
parts of the earth. The record trans
mission of a broadcast program is
held at present by station 2XAF, one
of the 15 stations whose programs
were picked up last Spring in
Johannesburg. South Africa, and in
Perth, Australia, being rebroadcast in
both cities. The same programs were
rebroadcast throughout the British
Isles by the British broadcasting com
pany stations. The wave length that
carried these programs and which
provided the record transmission is
32.79 meters.
Changes by Stations.
Several changes have been made in
the wave lengths used by others of
the General Electric stations, 2XAD
operating now on 20 and 26 meters;
2XX, heard previously on 109, 300
and 65 meters, now being operated
periodically on 140 meters. Station
2XAH, the high wave station, has
temporarily settled on 1,400 meters
for its signals.
The other licensed General Electric
stations are 2XAW, which uses the
lowest waves—between 3 and 20
meters; 2XO, 2XH, 2XA.C, 2XA55,
2XAK, 2XAG, 2XAM, 2XI and 2XAE.
The fifteenth station is the regular
broadcaster, WGY'.
