BULLETIN # 913
MODEL: TS-940S
SUBJECT: Signal to Noise Ratio Improvement


The following changes will reduce the tendency of the Zener Diode in the
Noise Blanker circuit to cause an increase in the ambient noise level.
This change ensures that no current flows thru this diode in the normal
receive position.

Parts Required:

560 ohm 1/4 watt resistor

Procedure:

On the IF UNIT  X48-1430-00 change R23 from 330 ohms to 560 ohms.

This change will be incorporated in all models beginning with serial number
603XXXX.

Time required for this modification is 1 hour or less.
