When doing the swing mod for the Cobra 29, the CBRadioMagazine page suggests adding a variable power with the added 33 ohm resistor and disconnecting the RF Gain wires from the pot and soldering them together. Then, I am to link wires from both sides of the 33 ohm resistor and run them back to the RF Gain pot. But - wouldn't this increase the resistance and thereby lower the dead key to the point where there is no dead key watts??? Can someone explain if this mod is correct - and more importantly why? I'm trying to learn what is happening. I know they are acting as two resistors in parallel. But how does two different resistors behave - when one is variable? Add the resistance any given variable resistance point in the pot with the fixed resistor - and divide by 2? In addition, what is the best single-final mod for this radio?
