14.1 Receiver Module
Description
The Universal Receiver Module is DIP switch
selectable for use as either a Receiver/AM
Detector for the TC–10B or a Receiver/FSK
Discriminator for the TCF–10B.
The Receiver Module comprises two boards. The
main board contains all the circuitry required for
the filtering and A/D conversions necessary to
process the incoming RF signal. The auxiliary
board contains DC-voltage regulators and compo-
nents specific to the Receiver/AM Detector.
The module’s double board combination slides
into the same slots as the previous Receiver and
Detector modules. The single Universal Receiver
with 2 boards replaced the 2 previous separate
modules (Receiver & Detector). With the new
Universal receiver, however, you do not need
extender cards to make adjustments or change
settings. You can perform all necessary settings
and adjustments directly on the front panel.
The Universal Receiver Module is driven by the
output of the RF Interface Module. The output of
the Universal Receiver Module drives the
necessary output module. The (primary) output
module for the TC-10B is the Receiver Output
Module, as shown in Figure 14–1. The module’s
audio output drives the optional Voice Adapter
Module and optional Checkback Module if they
are installed.
