Hello: Did the Inrad Audio modification on the IF/Audio board of one of my Omni VI transceivers. While looking for the R 38 resistor (100 K) which has to be chanced to 680 K I have noticed that R 39 which shows 3.3 K in the schematic (also in Omni VI+) has only 330 Ohms. Any info about that? 73s Wolfgang dk7cy
