Brad,
If you look REAL close, one of those is actually labelled "R201"
The "1" got overlaid by the box that represents the resistor contour.
I'd say that the one close to the keyer is actually "R201". The REAL
R20 is tucked next to the NE5532 chip.
Most resistors & diodes have a lead spacing of 0.4". So if you measure,
you'll find that D7 goes to the hole just outside the silkscreen
diagram. The hole inside is called a "via" and is used to make a
connection from topside to bottomside. No connections will be made
to this hole, so don't worry that D7 lays over it. There will be many
of these "via" pads with no connections when you're finished.
