The Alinco power supply for amateur radio has been around for a while but this latest model has some extra features.
All switch mode power supplies or their harmonics can interfere with some of our bands.
It appears to be well shielded and I have not experienced any noise on the HF band.
It has a noise offset control that allows you to move the interfering frequency away if you have any.
