RC-85 Repeater Controller Owner's Manual
Spare Audio
User commands may allow selections of a weather radio, scanner, or other audio
source. The audio input shares the Link / Remote Base receiver input and would
typically be available if the link function is not used in the system. The audio is
gated to the transmitter under computer control in response to the user
commands, and the transmitter PTT is held active. The audio may be
continuously present at the controller's audio input and no control signals to or
from the audio source are required.
Note: Retransmission of another radio service through the Amateur service may
not be legal.

External Tape Player

An external tape playback unit may be interfaced to the controller and
addressed by any of the programmable messages. Examples of applications
would include a tape recorded ID message or Bulletin Board accessible message.
When the controller generates a message which has been specified as an
external device (*13xx message loaded with speech "X" - see Chapter 7 -
Messages), a one second low going start pulse appears at User Function 2
(Control Output 2, or in the expanded mode at the recovered UF2). The
controller then monitors the External Device Busy logic input until the signal
goes low indicating end of message. Audio from the external device may drive
the Direct Transmitter Mixer Audio Input (J4 pin 3) and should be level adjusted
externally.

Digital Voice Recorder

ACC's Digital Voice Recorder may interface to the RC-85 controller so that any of
the remotely recordable "tracks" may be addressed through the Message Editor.
Control signals are passed to the DVR through Control Output 1 as part of the
serial data stream supplied at that output in the expanded remote control
output mode. Information from the DVR is supplied to the RC-85 controller
through the External Device Busy logic input. Audio from the DVR drives the
Direct Transmitter Audio Mixer input and may be level adjusted in the DVR.
Audio should be supplied to the DVR from the repeater receiver.
