In this video we tested and compared RFI from the following power supplies:
- Power supply with a buck converter (Switching)
- PC ATX power supply (Switching)
- HP Server power supply (Switching)
- Chinese power supply (Switching)
- MFJ power supply (Switching)
- Yaesu power supply (Regulated)
Used a 12V 35Ah battery to provide a clean baseline.

This was very informative. I suspected the MFJ was going to be somewhat dirty and was holding off purchasing one. After seeing your video, I am going to pick one up. I will get the same model only with the digital display. Hopefully, that won't impact the RFI in any way. Thanks for the information.

Very interesting presentation and nicely done. Thank you for sharing. I am somewhat surprised at how clean the Chinese PS is. There is so much bad press about Chinese hardware. 73's!

Thanks Bill. After uploading the video I found out that grounding the PS help to reduce further the RFI levels, specially on the HP Server PS converted. 73, Pablo
