Any schematic that does not show all connections is incomplete (HA).

Persistence seems lacking...
One of the problems with the schematics given with the
kits is not all of the connections are shown... For
instance, on the QLG1 GPS board for the U3s, there are no
connections shown for power and ground for IC1. On the
Relay-switched LPF kit there are a gaggle of connections
marked with X for jumpers/external connections, etc that
make it very unsuitable for debugging... Although most
commercial radio schematics have a whole lot more detail,
they are much easier to read as all the connections to any
plugs/jacks are routed to the side and grouped by the
plug/jack in numerical number, and jumpers are shown in the
default positions, etc.
