various rf leads as shorl as possible. Be sure that the filter cases are grounded (center solder pin) and that the i-f amplifier module cases are grounded (solder to one of the case labs). A somewhat awkward arrangement of trimmer capacitor is shown in the photograph. Two 25 pF trimmers were connected in parallel to duplicate the single 50 pF unit shown in the schematic for the balanced modulator capacitive balance. Two other trimmers were used in the crystal oscillator circuit which proved completely unnecessary and are not shown in the schematic.
