3.15 Install capacitors C5 and C8
These capacitors are band dependent. They add parallel capacitance to trimmer capacitor C1 to
bring it to the required value. The kit contains all required capacitor values. Install the capacitor(s)
appropriate to your band. Refer to the following table to find the correct capacitor value(s) for your
band. Where “none” is indicated in the table, do not install the corresponding capacitor.
