ONE FAN PLEASED,
HOOVER SHOCKED
Secretary Finally Finds Radio
User Who Is Really
Satisfied.
BY CARL III. BITMA\.

The other day Secretary Of Com
merce Hoover had a shock--not from
his radio set, but due to commenda-
tory letter from a radio fan. Instead
of being a complaint about interfer-
ence, the letter stated that there was
little difficulty in separating the Glass
Is stations. except two stations on one
wave length and three on another.
The writer John Young of Little
Current, Ontario, believes the present
arrangement of stations is very salts
factory and that much of the reported
Interference comes from owners OF
poor or badly operated receivers.
lIks letter to Secretary Hoover.
given the writer for publication, fol-
lows III part:
There has been a lot of discussion
in the radio columns OF the press late
1y about interference Of Glass sta
tionS on account of your recent sepa-
ration of these broadcasters by 10 kilo-
cycles. For your information and in
view of the approaching conference, L
should like to give You my expert
cnce as an operator of all types of re
ceiyinG sets for several years.
Likes Arrangement.
In my opinion the present arrange
ment of stations Is very satisfactory,
and much uf this interference talk
arises from owners of Door receivers.
badly tuned, and from a mlSconcep-
ton Of what causes heterodyninS nnd
crosS-talk.'
While experimenting one night re-
Gently. MIR. Young decided to log
number of the higherpowered United
States stations, noting any interter-
ence. This he did. listing SO stations
with good loud speaker volume in flVe
hours His only complaint is that
something ought to be done to get
WGR. Buffalo, and WSMB, New Or
leans, to split time on the 319-meter
wave. and TO persuade stations WNYC
New York: WHO. DeS MoineS. and
WOAW. omaha. to divide the time
three ways ON their wave length of
526 meters.
Outside of that" he reports. Glass
L stations are O. X.
AS for Glass \ stations" he con
tinues. nothing can be done. There
are 50 many on the same wave length
that serious heterodyning is bound TO
occur" he concludes. thanking the
Secretary for his interest in radio.
Mr.. Young assembled his set him
self the parts costing only S34.15
outside Of accessories. 1t is based on
and built up around radio frequency
kit and is regenerative in both an
tenua and radio frequency circuits,
but may be neutraliZed so that it will
not radiate energy. This type OF re-
Ceiver is not expensive, he points out,
but is well within the reach of all
radio fans.
Lists Sc Stations.
His log sheet is interesting, for the
40 notatiuns include So individual sta
tions. one of which was a 50-watter in
Michigan. lie picked up stations on
the Gulf and East Coasts as we'll as
he did those nearer his home.
The list includes stations in Chicago.
Cleveland. Schenectady, Detroit, New
Orleans, Cincinnati, Kansas City. To-
ronto. Boston. Pittsburgh. Providence
New York. Buffalo, Philadelphia, New
ark, st. Paul, Fort Worth, Atlanta,
Des Moines, Indianapolis. Grand
Rapids and several other points. Ex-
cept for the interference reported. he
found no cross-talk between stations
separated by 10 kilocycleS.
The Department of Commerce is
aware that sometimes the stations
mentioned do heterodyne each other,
but as they are so far apart and be-
cause they are also in different time
zones. II was thought that they would
not interfere seriously. However. Mr..
Goung's suggestions will undoubtedly
be considered by the radio conference,
and il other channels can be found
or these stations can be induced to
share time, efforts to clear up the two
bad spots on the "R" broadca sting
band will be made. But il is feared
that these stations will want to con-
tinue on their present schedules.
