Some of them are quite noisy. I found my MyDel unit spews all over 20m. No lower bands for some reason. The joy is it has a noise offset control so I can keep it out of what I’m working. Also the switcher in tek 22xx’s is noisy as anything.

Have decided to buy a big scary HP 30A 20V linear supply when one comes along. Missed one the other day unfortunately.
