11.1 Transmitter Module
Description
The function of the TC–10B/TCF–10B
Transmitter Module is to provide the RF signal
which drives the 10W
PA Module. The
Transmitter’s frequency range is from 30kHz to
535kHz, programmable in 0.1 kHz (100Hz) steps
by four rotary switches on the Transmitter. The
Transmitter is slaved to a crystal oscillator.
The TC–10B/TCF–10B Transmitter Module
operates from keyed inputs (set by jumpers at the
Keying Module):
• High-Level Key
• Any Transmitter Key
• Voice Key
• Shift High (TCF–10B only)
• Shift Low (TCF–10B only)
The Transmitter Module also operates with a
signal from the Optional Voice Adapter Module:
• AM Voice
The Transmitter Module operates with either no
shift (TC-10B) or one of three different frequency
shifts (TCF-10B), selectable by a four-position
dip switch (S5).
