County Seat Concerts
The county commissioners of Green
field, Hancock county, have given per-
mission to an Indianapolis firm to

Armstrong Super Hook-up

oped in a prize contest started by QST,

Use of a tube to drain out static is
reported to have been successful in
experiments made by DR.. Louis Cohen,
consulting engineer for the signal

signals are allowed to pass without

noises are blocked. DR.. Cohen is well
known as a radio inventor.
30o-MILE AERIAL
An aerial 800 miles long vas used
recently by a Postal Telegraph opera
tor to listen to a Detroit broadcast.
One of the main trunk wires of the
company was deadened and the receiv-
ing set connected to it as an aerial.
The Detroit end of the wire paralleled
the Detroit Free Press wireless aerial
and made a perfect conductor for Ty
Cobb's broadcasted talk.
Minneapolis Regulations.
Private broadcasting stations operat-
ed by three newspapers of Minneapolis
will be discontinued to- give way to
one large station operated by the Uni
versity of Minnesota. Eight large firms
also are cooperating in the establish
ment of another station the size of the
Detroit News station.
When the craze struck the city, the
three papers raced in putting up out
fits, one winning over the others by
only IL hours while the third followed
shortly after. All three broadcasted
as and when they pleased, all on $50
meters, two commercial firms started
to BROADCAST also, and two more edu.
cational institutions added their waves
to the general confusion, seven within
; | 100 miles and no traffic rules.
The large station will be supported
by a bank, three department stores
two electrical supply and one radio
supply company and a farm paper. II
will be equal to the Newark or the
Detroit News station. Its service will
be welcome to Minnesota amateurs as
the Minneapolis territory is dead tt
Chicago and no other large stations
are near.
