he CA -300 is available in a deluxe version known as the CA -300DX. he deluxe version contains a digital clock
and additional memory. his permits time of day announcements, scheduler activity, macros, telephone area code
and prefix number look-up tables, adds four memory saves and increases the speed dial memory locations from
twenty-five to one-hundred.
Scheduler [DX]
An advanced 40-position scheduler fully automates repeater operation. Any command that can be manually
executed can also be scheduled to one-minute accuracy. Program the hours, minutes, day of week, or day of
month and month of year. he CA -300 will do the rest.
Voice Synthesizer
A vocabulary base of 422 words carefully selected for amateur repeater operation are available to ID your
repeater, announce the time and interact with you during control and programming operations. Additional
message buffers can be activated on demand, through hardware inputs or by the scheduler.
Digital Voice Clock [DX]
he digital voice clock will announce the time upon request, at the completion of an autopatch, during repeater
IDs, or on the hour through the grandfather clock feature.
Autopatch
A full feature autopatch with storage for [25] or [100] speed dial numbers highlight the CA -300. Each speed dial
location accepts numbers of up to eleven digits and includes space for the users call letters. Regular calls are
preceded by a phone number read-back. his feature can be suppressed by a mic key-click. Hook-Flash and
autopatch time extender commands round out the features. In addition to the Reverse autopatch, full telephone
control and programming provides an extra measure of security. Long distance protection is provided by a
number counter with a first number 0-1 check. A user programmable pre-dial number buffer is provided for [9] or
[*67] caller ID suppression.
User Function Switches
hree user function output switches are provided to control equipment at your repeater site. hese switches can
be controlled manually by D MF commands, or by the scheduler during automatic operation. hey can be made to
turn OFF, ON or Momentarily change state, any time you choose.
Hardware nputs
wo hardware inputs activated by an input from other equipment at the repeater site, causes the CA -300 to
execute any repeater command. External repeater control or information about the repeater site will be instantly
available.

Chapter 3 - Repeater Control
he CA -300 has a maximum capacity of 64 remote control channels. hese channels are segregated into eight
zones according to their function. In addition to being controlled by the scheduler, these channels can be manually
controlled by D MF commands on the repeater, or telephone inputs.
nterrogation of Repeater Control Status by Radio
Key-up and send the control operator prefix number followed by the zone number and a zero. Un-key and the
voice synthesizer will read back the channels that are turned on in that zone. Example: "ONE WO FIVE ON." If
all the channels are turned off, the voice synthesizer will say: "ALL CLEAR."
Changing Repeater Control Status by Radio
o change the status of a channel, key-up and send the control operator prefix number followed by the zone
number, channel number and a [1] to turn the channel ON or a [0] to turn the channel OFF. Un-key and the voice
will read back the zone, channel number and control activity. he voice will say: "ONE ONE ON." or " HREE FIVE
OFF." Example: With a control operator prefix of 100, turn Zone 3 Channel 5 ON.
Un-key and the voice synthesizer will say: " HREE FIVE ON."
* he momentary command is limited to Zone 6, Channels 6, 7 and 8.
Changing Repeater Control Status By Telephone
Call the repeater by telephone. When the CA -300 answers a beep will be heard. Enter the control operator prefix
code followed by a (#) pound. he voice will say: "CON ROL READY." You need only enter the Zone number,
Channel number and a (1) to turn the channel ON or a (0) to turn the channel OFF followed by the (#) pound. It is
not necessary to enter the control operator prefix number before each command when controlling by phone. o

Zone 1 Repeater Control
1. Repeater Transmitter Enable
his is the master repeater switch. his channel must be enabled for normal repeater operation. he CA -300 will
continue to respond to control operator commands even when the repeater's transmitter is disabled. his channel
will automatically be enabled after an initialization reset.
2. Repeater CTCSS Enable
When this channel is enabled, in addition to a COR input, an input from a C CSS decoder at J3-4 must also be
present before the repeater will activate. A COR input by itself will have no affect. o prevent loss of control, DO
NOT ENABLE TH S CHANNEL unless a C CSS decoder is connected to J3-4.
3. DTMF Access Enable
When this channel is enabled, a D MF Access number selected by programming command *504* must be entered
to activate the repeater. Once this number is entered and the user un-keys, the voice will say: "OK UP". A COR
input will activate the repeater until it returns to rest. A rest period of up to 29 minutes can be selected with the
[*602*] programming command. When the CA -300 is initialized this timer defaults to 60 seconds. his timer
can be bypassed returning the repeater to D MF Access by sending the D MF Access number. he voice will say:
"OK DOWN".
4. Repeater CTCSS Override
When this channel is enabled, and C CSS is also enabled, a repeater user without a C CSS encoder can activate
the repeater by entering the D MF Access number. Once this number is entered and the user un-keys, the voice
will say: "OK UP". A COR input will activate the repeater until it returns to rest.
5. Turn on Delay Enable
When this channel is enabled, a deliberate and sustained input must be present before the controller will activate
the repeater. A time delay of 0.1 to 9.9 seconds can be selected with the [*603*] programming command. When
the CA -300 is initialized, this timer defaults to 1.0 seconds. his channel is useful during periods when noise
bursts are present on the repeater input.

6. DTMF Window
When this channel is enabled the controller will only accept D MF entries when the window is open. he pre-
window timer programming command [*613*] sets the time the window opens after the presents of COR. he
length of the time the window remains open is set by the window timer programming command [*614*]. When
the CA -300 is initialized the pre-window timer defaults to 2 seconds and the window timer defaults to 8 seconds.
herefore the CA -300 will only accept D MF entries from 2 to 10 seconds after initial COR.
7. DTMF Muting Enable
When this channel is enabled, anytime a D MF tone is received the audio will be turned off to the repeater's
transmitter. he transmit audio will remain muted until a pre-determined time after the last D MF tone is
received. his time is set by the [*606*] timer programming command. During the mute period, cover beeps are
transmitted each second to indicate repeater activity. his feature prevents control commands from being
repeated. It provides a extra measure of security. here may be times when it is desirable to pass the D MF
tones through the repeater. o temporarily disable D MF muting, precede the D MF string with a pound (#).
8. Control Operator CTCSS Enable
When this channel is enabled, a C CSS input is required for the CA -300 to accept control or program inputs from
the control operator.
Zone 2 Repeater Control
1. Repeater Timer Enable

When this channel is enabled, the repeater's transmitter will remain on for a period of time determined by the COR
Drop to Courtesy Beep imer [*604*] and Courtesy Beep to P Drop imer [*605*]. o make the transmitter
turn off the instant COR is lost, turn this channel OFF. his feature is useful when linking to other repeaters or
during band openings.
3. Scheduler Enable
When this channel is enabled, all action by the scheduler will be executed per the times programmed in the
scheduler table. here may be times, during emergency net operations, when it is not desirable to have channels
change automatically. o suspend scheduler operation, turn this channel off.
4. DTMF Pad Test Enable
When this channel is enabled, a repeater user is able to perform a test of their radio's 12 or 16-button key-pad.
As the numbers are being decoded, they are stored in memory. When the repeater user stops transmitting the
controller will read back all the numbers that were decoded. Do not use the [D] key during a pad test.
5. Repeater CTCSS OR Logic Enable
When this channel is enabled, the COR and C CSS inputs will function as a (OR) logic input. his means activity on
either the COR or C CSS inputs will cause the controller to key the repeater's transmitter. his is a layered
command. herefore, Repeater C CSS Enable, Zone 1 Channel 2 must be ON or this control function will have no
effect.
6. Grandfather Clock Sleep Enable [DX]
It may be desirable to suspend the grandfather clock operation during the early morning hours. When this channel
is enabled, the last announcement will be at 11:00 PM. ime announcements will resume at 7:00 AM the next
morning.
