BD3CG My FT-891 operates stably and normally, powered by either a 12V battery or a high-quality power supply.
bg5tlx I'm looking for a good quality power supply, but I think a high-end one is too much. They tend to have unstable voltage and fluctuate, which could damage my K3 if it happens again.
BG6UA I need a better power supply for this; it's not something you can skimp on. I think a vintage power supply, like the Jianwu PS-50, would be reliable.🎅
