ton and drastic action in this matter will
probably be taken. 1t is proposed to have
three wave lengths. one for commercial pur-
poses, another for broadcasting and the third
for the amateur. If this is done, the whole
matter of radio will be greatly lmplifietl
1t is obvious that it is desirable to keep the
attempts of the amateur out Of the way OF

Detection Is Unavoidable
1t may be questioned as to how this will

impossible to send and NOT to be detected
