I Don't Have Time To Read This Manual
If you are anxious to get the CAT-1000B in operating and don't have time to read this
manual, the following short version will appeal to you. This is a list of the minimum
steps required to install the CAT-1000B and verify its operation. Now fire-up your
soldering iron and lets get started.
1. Open the connector kit, remove the 2.5mm power plug and the 25 pin "D" male
connector. Solder a +12 volt wire to the center connector and a ground wire to
the outer connector of the plug. Connect the wires to a +12VDC power supply.
2. Solder five wires to the 25 pin "D" male connector. Connect wires to pins 6,
10, 11, 13 and 25.
3. Connect the pin 10 wire to the transmitter's PTT, the pin 11 wire to the
transmitter's modulation input and pin 25 to receiver/transmitter chassis
ground.
4. Turn the +12VDC power supply ON, the repeater should transmit and you should
hear the voice synthesizer say: "CAT1000 VERSION 4.03 AND 1.03." Adjust R23 TX1
control for proper transmitter deviation. Cycle the power supply and adjust R44
until the voice synthesizer is at the desired level.
5. Turn the +12VDC power supply OFF. Connect pin 6 wire to the receiver's COR or
COS output. Connect pin 13 wire to the receiver's RECEIVE audio output.
6. Turn the +12VDC power supply ON. Monitor TP1 with a DC voltmeter. Open and
close the repeater's squelch control while observing the voltage on TP1. If TP1
goes from LOW to HIGH dipswitch #1 should be left in the OFF position. If TP1
goes from HIGH to LOW set dipswitch #1 to ON. If TP1 stays LOW, turn the power
supply OFF and add a 2200ohm pull-up resistor on the CAT-1000B at the R74 pull-
up resistor position. Note: LOW is any voltage less than 0.8VDC. HIGH is any
voltage between 3VDC and 15VDC.
7. Turn the +12VDC power supply ON. Connect an AC voltmeter to TP8. Using a
typical transceiver, key-up and send a DTMF tone. Adjust R28 RX1 control for
200mV as indicated on the AC voltmeter. If this causes the repeater to over
deviate, readjust R23 TX1. Make sure that RF from the transceiver does not give
a false voltmeter indication.
8. Compare the receive and synthesized voice audio and adjust the VOICE Level (R44)
as desired. For best quality speech, the synthesized voice should not exceed
3KHz deviation and always be lower than the receive audio.
9. Compare the receive and CW ID audio and adjust the CW LEVEL (R21) as desired.
For best results the CW ID should not exceed 1.5KHz deviation. This will insure
that repeater users will always be able to talk over the CW ID when it comes on
during a QSO in progress.
10. Compare the receive and COURTESY TONE audio and adjust the COURTESY BEEP LEVEL
(R29) as desired. For best results the COURTESY TONE should not exceed 1.5KHz
deviation.
11. Connect a phone line to the RJ11 jack. Key-up and enter [* PHONE NUMBER], un-
key. The voice synthesizer will say: AUTOPATCH read back the number, wait two
seconds, take the phone off hook and dial the number. During the autopatch,
adjust the PHONE LEVEL IN (R41) for the desired level of phone audio at the
transmitter. The phone audio input should modulate the transmitter at the same
level as audio from the repeater's receiver. Adjust the PHONE OUT LEVEL (R13)
for the desired level of receive audio into the telephone line. Key-up and
enter the [#] to disconnect the autopatch.
12. Key-up and enter the seven digit unlock number [1234567]. The voice will say:
"CAT-1000B CONTROL."
