Note 1. I made a mistake in the layout here.
These 4 pins of DIP switch should never be
connected to ground, so do not push
pins through the holes. Note 2. This part as
laid out is for the circuit that does not contain
modulator. If you are planning to implement
a modulator by modulating the reference,
you can use this part add modulating voltage
through the BNC connector and add a
varactor or a BJT (as a varactor).
