I recently installed a G50 receiver circuit board under the floor of the MOOER P6 miniature pedal board and case. Took quite a bit of work, cutting away some of the rubber floor support but I managed to get it in there. It worked for my show on the crusie ship, thank God, but now I am getting the dreaded red lights again, and switching from R1 to R2 makes no difference. I had this issue even before the cruise; sometimes it worked, sometimes it did not. I bought the receiver used on E-Bay which I am beginning to think was a mistake. But what causes these red lights and no reception?
