WebThis is a QRP power level SMD Dummy Load, 40-2000 ohm 1/4 watt 1206 SMD resistors are soldered in parallel to make a 50 ohm load. An RMS RF probe is included to estimate output power with your DMM and an oscilloscope for monitoring waveforms can be connected also. The design survived a 2 hour test at the 4 watt power level. Documentation ... WebIn this video, I build a simple QRP Dummy Load that is good for up to 20 watts. It even has test point that you can use a meter to measure the voltage to calculate the power of your transmitter.
WebSep 19, 2011 · This 100w dummy load only needs about a half hour more work and today was a good day to do it. I fired up the soldering iron and soldered the remaining ten 1K Ohm resistors onto the board. (shown below) The next step was to test to make sure all the resistors were secure and see how close to 50 Ohms I would be. I call 50.6 close enough … http://www.4sqrp.com/4SDL.php
