Sixty kilocycles, which is about 5000
meters, We're selected for the trans
atlantic telephones wave frequency,
following experiments in which radio
stations in many countries took part.
Today the system is operating freely
on a band between 5S u kilocycleS

The British end of the telephone
system is operated by the British
post Office, and cooperation was
merely q routine matter between gov
ornamental agencies. But on this end
the Nays cooperation with the
American Telephone and Telegraph
Co. pr waite concern, operating the
American side of the system, was in
virtue Of an attitude OF helpfulness TO
commercial radio progress.
Radiotelephony requires broader
band than biography, and numec Gus
experiments on the proper band for
the transatlantic system had to be
made.
The experimenters first tried the
Silocycle band from SIS to 5S32, but
while no interference was reported in
this country there was interference
with transmission IN England, Ceylon,
Chile and even In Moscow, according
to reports that came back. Then they
tried 50 to 60, but the interference
persisted Finally, they hit upon the
5S1b to GLE kilocycle band.
Some interference was reported from
abroad. SO far as the Navy was con-
cerned, the interference was over a
band of six kilocycles, in which We're
operating the naval radio stations at
Port au Prince, San Juan. Bar tarbor,
San Francisco. San Diego, Browns
vile, Tex, and North Head, near
Astoria, Greg. Their frequencies We're
from 50 to So. Charleston could oper-
ate on "a, and Norfolk and Puget
Sound reported no interference on Sc.

Completely musical in character, the
bill features the Kilt hour of music,
with Esther Cutchin, noted pianist
and recording artist, and an hours

tenor.
Statisticians at WEAF have just
completed tabulattons which show that
the station was on the air-or, in
other words, in actual operation-for
1884 hours and As minutes during
1926-an average of 10h hours every
day@ during the the year. The sta
tistics were compiled from the sta
TONS log, which also revealed that
the daily average operating time In
creased from s hours and "a minutes
in January to IL hours and Is minutes
in December. In spite of this steady
increase in operating time. the time
off the air, due to both technical diff
culties and studio delays, showed a.
continual decrease.
These statistics are graphic cyl
dence of the stations efforts to i'm
prove it's broadcasting service.
Static returned last night, in a mild
form, however, and tended to coun-
teHact the excellent reception condi-
lions of the two preceding nights.
The signals of the distant stations
lacked clarity, and fading also was
more pronounced. Yet the night was
productive of fair results for the DIX
hunters.
The Southern stations, notably
WSB, Atlanta; WMBF', Miami Beach,
+ and WQAM, Miami, Fla, came
through with good volume, but an
: annoying heterodyne whistle spoiled
reception Of WAX at Jacksonville.
