    I have an auxbeam switch panel and controller. Currently there are only 4 devices hooked to it: cali raised ditch lights, some cheap Amazon rock lights, and two micro tuning scene lights (wired separately). My GMRS is tapped into a circuit inside the truck.

    Originally, when i turned my ditch lights on, it created a buzzing in the gmrs like someone was just holding down their button out of range. I just added the scene lights... now it's one of those that do it and the ditch lights dont bother the radio at all anymore. I'm kinda stuck. Any suggestions on what could be causing this?

    You're getting interference from the led lights. I know because I have the same issue whenever I have my lightbar on. lol I have the Midland MXT 275 tapped into a 12v switch circuit as well. I'm about to relocate the power source directly to the battery to see if they'll help.

    LED lights are electrically noisy. There isn't much you can do about it besides convert to halogen.

    Try powering the radio directly from the battery.
