COLLINS 432D-2

GENERAL DESCRIPTION

432D-2 2.5/2 KW TRANSMITTER

Covers the 2 to 30 mc frequency range with 10 crystal-controlled channels rapidly and automatically tuned by Autotune® system.

The 432D-2 has a power output of 2 kw AM and 2.5 kw CW and FSK. FSK may be employed on up to three of the channels by installation of 709E-1 Frequency Shift Oscillator accessory units in the transmitters.

One of the 10 channels may likewise be derived from an external signal source, such as a stabilized master oscillator.

Remote control of all transmitter functions is available with the 177M-1. Channels are easily preset by Autotune® tuning controls on the front panel of the transmitter.

Improved performance is achieved by modern components, such as vacuum variable tank capacitor and beam power tetrode.
