Collins

32S-3A

is a highly llexible transmitter covering

all the amateur

bands between 3.1

MHz and 30.0 MHz.

The

32S-3A is rated for

a nominal output of 100 watts

and

power

input

to the final amplifier is rated

175

watts

PEP on

single sideband and 160 watts on CW.

Simplified

controls on the 325-3A make

tuning

quick

and

precise.

Front

panel

controls are: Power,/MIC

GAIN, CW CAL, FREQ CONTROL selector, EXCITER

TUNING, BAND

switching,

VFO tuning,

P.A. TUNING

and LOADING,

EMISSION.mode selector, and a MET-

ER switch which selects

between

ALC, P.A. Grid and

P.A. Plate.

The extra large, finely calibrated VFO dial

provides

that

extra measure of confidence when operating near

the

edges bf the amateur bands while the

VFO tuning

mechanism

itself is shaped to flt the hand and designed

to minimize

mechanical back

last

The 32S-3A can also

adapted for RTTY opera-

tion because of the high degree of stability of the unit.

For RTTY, the 516F-2

Power Supply and a source

external

cooling air should be used.

POWER REOUIREMENTS:

Power can be

dclivered by an external supply such as

the

5l6F-2

which must furnish 800
