Anker usb-c power supply RFI

February 28, 2026

Got this Anker power supply for my station computer: Anker MacBook Pro Charger, Compact and Foldable 100W USB C Charger for MacBook Air, Samsung Galaxy, iPad Pro, and More, 5FT USB C Cable Included

It was noisy especially on 80m, so it needed the “treatment”:

Ferrite rings on both sides of the power supply.

Update: It was still a bit noisy after this – ended up using another power supply…
