[QUOTE="ozziii, post: 192758, member: 3482"] Question, will running a higher voltage make EMI more noticeable.? Today we tried using the 1.5v alkaline batteries, I checked the voltage output from the battery tray & it was 13.31v. When I turned detector on there was noticeable interference, more than I've had before even when near a mobile phone tower & HV power lines, but the place we were at didn't have that around, only normal power lines about 200m away. If I turned gain down to just above half way it was ok but still made a slight warble here & there but turning gain to 3/4 or more caused more interference noise & was harder to tune. As this was the first time we used batteries with a higher voltage I was just wondering if that would have something to do with it. I couldn't try the rechargeable pack as we left it at home. Thanks.
