BULLETIN # 1007
MODEL: TS-950SDX
SUBJECT: Speech Processor

Symptom:

Reports of low COMP meter sensitivity, or noise on the transmitted audio 
when using the speech processor is normally a result of misadjustment of 
the PROC IN control.  This control is very sensitive and is difficult to 
adjust properly.

Parts Required:

150 ohm chip resistor  Kenwood Part No:  RK73FB2A151J

Procedure:

Change the value of R258 in the SIG Unit (X57-4130-00) from 68 ohms to 
150 ohms. This will increase the available adjustment range of the PROC IN 
control. This will make it much easier to properly adjust the control and 
thus avoid overdriving the speech processor circuit.   

R258 is near L25 and Q33 on the foil side of Signal Unit (x57-4130-00).

Caution: This modification requires soldering equipment rated for CMOS type
circuits.It also requires familiarity with surface mount soldering
techniques. If you do not have the proper equipment or knowledge do not
attempt this modification yourself.  Seek qualified assistance.

Time required for this modification is 30 minutes or less.
