Hello, I'm Spinningspark. An edit that you recently made to Standing wave ratio seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! SpinningSpark 00:06, 25 May 2017 (UTC)
