not an effective wave to cover such a
long distance.
At AIS am. Iverson again picked up
the signals from the plane on the "a
meter channel, which this time sue
ceeded in talking with the radio men at
rhe Mussel Rock station of the Robert
Dollar Co., IL miles from San Fran
cisco, which reported to the New York
Times as follows:
"Mussel Rock Radio Station, Rob-
Crt Dollar Co. established two-way
radio communication with Byrd plane
Stars and Stripes, exchanging following
messages single at Is words per minute
without difficulty: VIC Fairchild

Heintz, San Francisco: Congratula-
tons to you on performance of your
airplane translnitter on occasion of es-
tablishing this worlds record for two

MusSel Rock replied:
ITO Hanson, airplane Stars and

surely am proud to be so fortunate as
to be party to this remarkable accom-

The Transmitter Equipment.
Radio men rate signal strength from
to 10; the latter figure denoting a very
loud signal. Hanson reported on this
basis that the Mussel Rock signal
strength was Z, and Mussel Rock
reported the intensity of the signal
from the plane was of siX-degree in
tenSity. So.
The radio transmitter that made the
new record was built by Heinz &c Kauf:-
mann at San Francisco It is described
as high-frequency and intermediate
frequency transmitter employing ,one
50-watt oscillator tube, which is about
as powerful, as far as electrical rating
is concerned, as an ordinary incandes-
cent lamp. The Stars and Stripes is
equipped with what is termed a fixed
doublet antenna, reaching from the tips
of both wings to the tail and into the
fuselage. This is for short-wave trans
mission. while trailing wire Is utilized
for communication on the universal
commercial wave of 600 meters The
installation is powered by an electrical
generator coupled direct to the airplane
engine. This is an innovation in air.

The planes receiver, which picked up
the signals from the Times station, is

Look for New Triumphs.
So strong were the signals from the
plane and so slight the fading, the bane
of Short-wave radio, that, the Times
operators are hopeful that they will pick
up the planes dispatches as the Stars
and Stripes flies over the South Pole,
provided the flight is made between
midnight and am, New York time,

quer the obstacles that Turk in the radio

Comdr. Hooper last night sent the fol-
lowing message to Radio Officer Hanson
OF the Byrd expedition:
Your message received by air from
the air. Wonderful record and inter-
esting. Hope to receive one when you
are over the South Pole. Envy you, as
no sunny nights here now. Communi-
cations and laboratory personnel join
