TS-430S Noise Blanker circuit
Some operators have indicated a desire to have their TS-430S noise blanker operate similar to the noise blankers in the TS-120S/130S series. By performing the following modification the operator will be able to increase the effectiveness of the TS-430S Noise Blanker circuit.
Procedure
On the RF unit (X44-1510-xx) change the following components.
R80 change to a 100 Kohm ¼ Watt resistor (RD14CB2E104J)
R81 change to a 56 Kohm ¼ Watt resistor (RD14CB2E563J)
C125 change to a 560pF 25V disc capacitor (CK45BIH561K)
This is an optional change and may not be performed in-warranty.
No realignment is required.
