5Watter Organic Transceiver Build Phase 1: Power Supply

When building the 5Watter by W8DIZ, K7QO recommends building the power supply first as a troubleshooting measure. If the voltage regulators are installed and giving correct voltages, then you’ve eliminated one potential problem down the line.

Ouachita National Forest, K-4244

Camping in the Ouachita National Forest In Arkansas, national forest land abounds. Fifty-six percent of the state is wooded, of which thirteen percent is national forest.
