Once  the  RX1,  and  RX2  audios  are  adjusted,  key-up  on  the  repeater  input  and  send  a  DTMF  tone.  

Monitor  the  REPEATER  transmitter.    Adjust  the  TX1  Audio  level  control  (R15)  as  required  to  set  the 

repeater  transmitter  deviation  to  3  KHz  or  as  desired.  If  the  repeaters  transmit  audio  input  is  very 

sensitive and you find the TX1 Audio level control near minimum, it is strongly recommended that an 

external voltage divider be installed at the audio input of the repeater’s transmitter. 

 

If a link transceiver is connected, key-up on the repeater input and send a DTMF tone.  Monitor the 

LINK  transmitter.    Adjust  the  TX2  Audio  level  control  (R16)  as  required  to  set  the  link  transmitter 

deviation to 3 KHz or as desired.  If the link-transmit audio input is very sensitive and you find the TX2 

Audio level control is near minimum, set the jumper plug at J5 between pins 1 and 2. 

 

Compare  the  receive  and  synthesized  voice  audio  and  adjust  the  voice  Level  (R30)  as  desired.    The 

synthesized voice should be slightly lower than the receive audio. 

 

Unlock  the CAT-250 by keying-up on the repeater input and entering: [1234567]. Key-up and enter 

the [*901] test tone programming command. Verify that the test tone provides approximately 1.5 KHz 

transmitter deviation.  Key-up and enter [*0] to exit the programming mode. 

 

Repeater and Link Interface (J2) 

Connector J2 provides an interface to the repeater and transceiver.
