DF8OE suggest to replace the two parallel tantal capacitors next to the 3.3V voltage regulator by 100nF & 1uF. He also suggest to put 100nF & 1uF in the free location shown in Andy's photo. | DF8OE suggest to replace the two parallel tantal capacitors next to the 3.3V voltage regulator by 100nF & 1uF.
