The NorCal BLT Tuner Fig. 12 QRP Kits Pacific Antenna The circuit also includes the famous N7VE LED SWR indicator circuit. Dan Tayloe invented this several years ago, and it has proven a great addition to the qrp fraternity. This allows us to have an indication of lowest SWR on the tuner (indicated by the dimming or LED going out at minimum SWR.) The circuit also is an absorptive bridge, which means Homebrew Antenna tuner for QRP | QRZ Forums Unfortunately, "QRP" operation and miniaturized antenna tuners are sort of mutually exclusive. When running QRP, you would want the MAXIMUM efficiency from a tuner, but miniaturized components (small coils made of small diameter [high AWG #] wire and miniature variable caps) increase the loss in the system, making your QRP signal even weaker.
