All equipment with a three-wire power cord must use a true grounded outlet. "Cheater" adapters that bypass the third pin are hazardous and should never be used.

Proper power management is the first line of defense for both the operator and the gear. Power, Grounding, Bonding, and Audio for Ham Ra...

Switch-mode power supplies (SMPS) can be a source of significant radio noise if not properly filtered. Experts recommend keeping the metal chassis of all AC-connected equipment bonded to the AC safety ground. 3. Managing RF and Interference (RFI) All equipment with a three-wire power cord must

refers to the intentional connection of an electrical system to the earth. This provides a path for static charges, stray currents, and lightning to safely dissipate.

Many hams mistakenly chase an "RF ground" to fix interference, but at radio frequencies, long wires have high impedance and do not act as effective grounds.
