Power And Swr Meter Arduino - Arduino Based SWR/PWR Meter - The Board - Experimental ... / Usually the swr meter does show some reflected power with this test.. See appropriate #defines in the pswr_x.h file, included in the source code. I just have to key the mike to see the swr. The swr meter should show a standing wave ratio of approximately 1:1.5 or lower. Mine is automatic when it is in the swr mode on the radio. Some meters you have to zero.

The swr should be ok with this if your solder joints are good. This posting is the c++ arduino uno processor code for an experimenter's variable voltage transformer. However this would result in approximately 500 µa of idle current constantly flowing through r4 into pin 7 while the system is turned. It's also possible to test with a half wavelength of wire. See appropriate #defines in the pswr_x.h file, included in the source code.
