• HT and Light Bulb Load
  The light-bulb dummy load has been used with HF transceivers from way back in the old days (and sometimes more recently). Also, the Lightbulb QSO Party promoted the use of light bulbs as antennas. I wanted to find out if I could do the same thing with a 5W handheld transceiver, so I scavenged a … Continue reading HT and Light Bulb Load →

View in browser POWER MOSFETs PART 2 Last time, we examined how to use power MOSFETs. This time, we’ll build two projects. The first project is a transformerless voltage doubler that takes a DC voltage from 12 to 30 volts and doubles it. Unlike most other voltage doubler circuits, this design can supply amps of current. The second project uses a power MOSFET in a linear (rather than switching) application. Read It Now!
