Power And Swr Meter Arduino - Rf Level Meters With Ad8318 Radio Club Pzk Lab El Hf5l / 12w dummy load / power meter;. Use an arduino to draw pictures on an oscilloscope using xy mode #79: Usually the swr meter does show some reflected power with this test. However this would result in approximately 500 µa of idle current constantly flowing through r4 into pin 7 while the system is turned. And this is only the beginning! See appropriate #defines in the pswr_x.h file, included in the source code.
Use an arduino to draw pictures on an oscilloscope using xy mode #79: In this experiment were going to explore the use of a 1:64 matching auto transformer on the end fed long wire antenna. 12w dummy load / power meter; Qrpguys digital power/swr meter w/dummy load; Mar 24, 2018 · the same circuits can be used for the rf power coupler and the ad8307 as in the original power and swr meter project, however a few new builds are shown below.
