Install capacitor C30
This capacitor is band dependent. The kit contains all required capacitor values for all bands.
Install the one appropriate to your band. Refer to the following table to find the correct capacitor
value for your band:
Band
Value
Label
80m
180pF
“181”
60m
30pF
56pF
“300”
“560”
40m
56pF
“560”
30m
30pF
“300”
20m
30pF
“300”
17m
30pF
“300”
60m important note:
for the 60m band, the capacitor requires both the 30pF and 56pF capacitors
to be soldered in parallel, but there is only one component position on the PCB. For 60m, you will
need to install one of the capacitors (e.g. 56pF) in the component holes provided, and solder the
other one (e.g. 30pF) to the same pads under the PCB. Take care to keep the component wires
short and not accidentally touching any other nearby components or soldered pads.
80m important note:
the 180pF capacitor supplied has a 0.2-inch (5.08mm) pin spacing. But the
holes on the PCB are spaced 0.1-inch (2.5mm). It is necessary to squeeze the capacitors wires
carefully closer together to fit the PCB holes.
