Good morning, Has anyone noticed a slight background noise increase from both the KPA1500 amp and its power supply? It seems the background noise on the waterfall of my Flex radio goes down about 2 db when I turn off the amp and another db or so when I turn off the power supply. It’s about a 3 db overall increase when both are on. I’ve noticed this on 80 meters and to a lesser extent on 40 meters. It is imperceptible on 20 meters. There’s too much local noise to see anything on 160 meters.
