It's common practice with solid state electronic not to show the power pins on the chips.

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.
