Dick, Guess I wasn't very clear. The tuning capacitor has two sections (front and rear). One for tuning the RF and one for tuning the oscillator. The usual arrangement is the stationary plates are connected to their respective circuit and the rotating plates are grounded. If the stationary plate section is also temporarily grounded it disables the function of that circuit. I don't know if the front section is the rf or osc. If that worked it would save disconnecting the antenna. Not a big deal but I'm lazy.
