garikfox Posted February 25, 2020 Share Posted February 25, 2020 I was noticing "coil whine" coming from the control box. I'm sure it's normal but was wondering does anyone else hear this? very high pitched squeal or whine, very faint. I also have a GM1000 and I don't hear it on that one. Edit: Interesting! Seems to be more prevalent when using Multi. Link to comment Share on other sites More sharing options...
Skookum Posted February 26, 2020 Share Posted February 26, 2020 Yep. I’ve noticed it when leaning near the unit. 1 Link to comment Share on other sites More sharing options...
nordic Posted February 26, 2020 Share Posted February 26, 2020 Have that too, faint hiss. Sound of switching power ouput. Link to comment Share on other sites More sharing options...
midalake Posted February 27, 2020 Share Posted February 27, 2020 I hate whines, would much rather have wines at the end of a good hunt. Have not noticed that on my 800. Dave Link to comment Share on other sites More sharing options...
