NOTE: In the following step, install the
12 pF capacitor for a 2-meter built-in
calibrator. Otherwise, use the 14 pF
capacitor. See Power Meter Calibration on

off the excess lead lengths. NOTE:
Save one of the excess lead lengths
for use in later steps.

Refer to Detail 2A and install the
-56 pF phenolic (green-blue-gray).
Position this capacitor vertically
against the circuit board as shown.
The free end will be connected later.

( ) Install the toroid coil as follows:
Position the three toroid coil leads
as shown, and push the leads
through the circuit board. NOTE:
Be sure the twisted pair of leads goes
into the center hole. The lead
coming from the top of the coil
must go to the hole nearest D3, and
the lead from the bottom must go to
the hole nearest D2,
Carefully push an eyelet through the
center of the toroid coil. Do not
force the eyelet. Then push the
eyelet through the circuit board and
solder it to the foil.
NOTE: (f an ohmmeter is available, check
between the eyelet and one of the coil
leads to be sure they are insylated.
3. Solder the tinned ends of the three
leads to the foil and remove any
excess lead lengths.
