Communication Associates, Inc.,
(CAI), recently combined the open-
ing of its new facilities with the
introduction of a 40-channel single-
sideband, marine communications
system which features an auto-
matic frequency and mode selec-
tion.
This new marine unit, Model
CA-35MS, has a pre-programmed
control unit and an integrated cir-
cuit digital frequency synthesizer.
The system covers a frequency
range of 2.0 through 30.0 MHz.
It contains three basic units—pro-
grammable control unit, frequency
synthesizer and single-sideband
transceiver. The user picks the
channel by the turn of a thumb-
wheel selector. A punched metal-
lized card, pre-programmed to a
particular frequency, is in turn de-
coded by the built-in optical card
reader. The frequency and mode
selection is thereby automatically
accomplished.
The control information is then
fed into the frequency synthesizer.
A built-in laboratory-grade temper-
ature compensated crystal oscilla-
tor is used as the primary frequency
standard.
CAI has designed the unit to
provide:
First, as long as the unit is oper-
ated within the temperature range
of -40°C to 85°C, the transceiver
is on frequency the moment the
unit is turned on. This reduces the
warm-up time to approximately
one minute.
Second, by using a pre-program-
med synthesizer that automatically
provides the correct frequencies,
the need for a trained radio oper-
ator is minimized. The operator
merely selects a given channel,
without any control over actually
varying the assigned channel fre-
quency.
Third, since all frequencies re-
quired by the transceiver are de-
rived from a single standard, there
is a reduction in frequency mainte-
nance. Depending upon the stand-
This is how the newly lengthened ships of the fleet of Lykes Bros. Steamship Co.,
Inc., look after adding a new 97-foot mid-body section. Todd Shipyards in Galveston
are converting the ships at a cost of $30 million.

quencies. Cards can be changed in minutes,
even at sea.
ard selected, the system offers high
stability in the order of ^-part-
per-million or better.
Fourth, frequency changes can
be made within a given band with-
out the services of a special tech-
nician. By a change of the channel
program card, a change of frequen-
cy may be accomplished at sea.
Fifth, the synthesizer can be used
for half-duplex telephone operation
by providing separate transmit and
receiver frequencies. This is made
possible by the ability of the unit
to lock on a new frequency with
loop acquisition time of less than
100 milliseconds.
Providing ISO-watts peak en-
velope power output in a single-
sideband or AME modes, the trans-
ceiver offers 10 bands over its 40
pre-programmed channels. They
may be used for either simplex or
half-duplex operation.
The CA-35MS has been designed
to comply with FCC type-accept-
ance requirements for harmonic
and spurious emission, without the
need for auxiliary filters, couplers
or other external device.
The new plant of Communication
Associates, Inc., at 200 McKay
Road, Huntington Station, N.Y.
11746, is now in full operation, pro-
ducing communication equipment
and systems for the marine and
aviation industries.
The first of nine ships of Lykes
Bros. Steamship Co., Inc., to be
"jumboized" in a $30,000,000 pro-
gram to convert them to combination
breakbulk and containerships recent-
ly went into service on a voyage from
U.S. Gulf ports to Continental Eu-
rope and the United Kingdom.
Lykes officials announced that the
S/S Zoella Lykes' discharge ports in
Europe will include Bremen, April
21; Bremerhaven, April 22; Ham-
burg, April 23; Rotterdam, April
24; Antwerp, April 26; LeHavre,
April 28, and Southampton, April
30.
The ship is expected to lift a full
load of 158 containers, in addition
to its other breakbulk cargo. The
new 97-foot mid-body section, added
just forward of the main deckhouse,
makes it possible for the vessel to
carry 60 containers under deck and
98 on deck, two tiers high. New car-
go gear installed at the new container
hold can handle lifts up to 35 tons.
In addition to the new container
facilities, side ports have been in-
stalled in the ship to permit fork
lift trucks to operate between ship
and dock for improved loading and
discharging of unitized and palletized
cargo. An 800-horsepower bow
thruster has also been installed to
provide for improved maneuvering
of the ship in port areas.
The conversion was done in the
Galveston yard of Todd Shipyards
Corporation. The vessel was length-
ened from 495 feet to 592 feet. All
nine ships involved in the conversion
program are comparatively new units
of Lykes' Gulf Pride Class and the
nine ships will hereafter be known
as the Gulf Pacer Class.
The other eight vessels are slated
for conversion and re-delivery to the
Lykes fleet at 60-day intervals. The
stretching of the ships adds more
than 40 percent to the cargo capacity
of each vessel. The total for the
nine ships adds a total of about
2,000,000 cubic feet of cargo space
to the Lykes fleet, or the equivalent
of three new ships.
In addition to the Zoella Lykes, the
other ships to be jumboized are the
James Lykes, Joseph Lykes, John
Lykes, Thompson Lykes, Solon Tur-
man, Nancy Lykes, Jean Lykes and
Leslie Lykes.
