Locate C45, 68 pF (68 or 680), LS 0.2. Be sure that you do not

confuse this capacitor with C56, also 68 pF but with 0.1” lead spacing,
that has not been installed yet. Note: C45 may be a much larger disc
type, which would not fit in the location for C56. But if both are small,
you’ll need to go by the lead spacing.

Install capacitor C45 to the left of C46 in the upper right quadrant

of the board.

Install capacitor C26, 120 pF (121) pillow-style disc ceramic,

about 1/2” (1.3 cm) below C45. Be careful not to put this capacitor
in the space for C44.
When C26 is installed, the space for C44
between C26 and C45 should be empty.

Test fit capacitor C1, 4.7 pF (4.7) pillow-style disc ceramic, next

to the lower right corner of the encoder. The bottom of the round
capacitor body should touch the board. If the ceramic coating on the
leads runs down too far to allow it to sit against the board, remove the
excess by squeezing the coating with long-nose pliers. It will crumble
and can be scraped away from the lead.

Install capacitor C1, 4.7 pF (4.7) making sure the bottom of the

round body is touching the board.

The following capacitors must be mounted closer to the

board than the others. They are installed in the area that lies
beneath the optional KXB30 30 meter or KXB3080 30 and 80
meter module. The KXB30 or KXB3080 module will not fit if these
capacitors sit too high above the board.

The capacitors installed in this step must be closer to the board

than any of the previous parts you have installed. After installation,
these capacitors must not exceed 5/32” (3.9 mm) in height.

_ C11, .1 µF (104) to the right of molded inductor L10.

_ C13, 56 pF (56) to the right of C11.

_ Use a ruler to verify that the above capacitors are no higher

than 5/32” (3.9 mm) above the board.

On the bottom of the board, ensure L5 (installed earlier) is

against the board, or it may strike other components when the KX1 is
assembled.
