City usef Either 1t Is has an elastic

Thursday night picked up at 11:15
o'clock a baritone solo, followed by
a piano solo, announcements IN Span
fish, on about 395 meters. Upon learn
ing that Madrid transmitted on 392
meters, was considerably elated.
only to have the sweets turn to ashes
when 1t appeared in The Star that
an Army officer identified that sta
tion as Mexico City, broadcasting on
405 meters.
Friday night L heard music and
announcements on apparently 49o
meters. One of my fellow employees
claimed he distinctly heard this sta
tion, getting it's call letters and To-

the legion of oscillating regenerative
sets were several phrases in English
which were heard distinctly. In Sun

when he is told. regardless OF wave
length, time or language, that the
station he heard was Mexico City.

gator might drop his crossword
puzzles for while and solve this
perplexing mystery of the ether. IT
looks as though somebody's wrong

formation that the two Mexico City
stations, CYL and CYB transmit on

about a wave length of 400 meters.
4 heard a soprano solo and several
piano solos, after which followed q

the signals faded SO that I was un-
able to hear the call letters. The
old-time melodies were played on a
