QRP Operating Includes:QRP basicsQRP equipmentQRP operatingIt is possible to use many forms of equipment for QRP operation. It is often possible to use the main station rig in a QRP mode, but for many people QRP operation means a little more - operating with equipment they have built themselves.As a large number of people enjoy QRP amateur radio, there is a large variety of equipment, ready built, in kit form or circuits that can be built relatively easily.
