digital or analog type. Besides, you will need an electric drill and a 3 mm drill bit,
a 50 Ω, 20 W or higher power dummy load, an HF band SWR/Power meter, a 13.8
V/ 3 A power supply, a personal computer running Windows, an amateur radio
transceiver with a general coverage receiver and calibrated frequency display, and
other ancillary instruments. It will be nice if you have access to a frequency
counter, an audio signal generator, a RF signal generator, an oscilloscope and a

Board Assembly
We will do it step by step, finishing one part of assembly at a time, and testing it to

understand the theory of operation, and make sure you install all the parts required
to do the final testing of the block.
However, the partial schematic might not contain all the parts you should install in
each step, so don't get confused when you are told to install a part not shown on the
