Meanwell switching power supply

The Quickstart refers to a Mean Well switching PSU which "we have found to be fairly quiet". Following a PSU discussion on a Perseus reflector, I decided to buy the 3A version for testing. Tested with the CloudIQ, it worked very well indeed, with no RFI showing up anywhere in the spectrum. However, nearby Kiwis were affected with one antenna connected, not with another. When I tested it on one of my Kiwis, I got severe RFI on the lower frequency ranges, see attachment. I guess "fairly quiet" stands, but not on MW and LW. Jpg shows the LW spectrum when powered by my Bel Power PSU vs. Mean Well PSU.
