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.
In the amateur radio world, "grounding" and "bonding" are frequently used interchangeably, but they serve distinct purposes:
Proper power management is the first line of defense for both the operator and the gear. Power, Grounding, Bonding, and Audio for Ham Ra...
Establishing a safe and high-performing amateur radio station requires a deep understanding of four pillars: . While often discussed as separate topics, they are deeply interconnected; a failure in one can lead to "RF in the shack," equipment damage, or poor signal quality. 1. The Foundation: Grounding vs. Bonding
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. All equipment with a three-wire power cord must
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)
Every station should ideally have a single reference point for all grounds. Connecting to multiple disparate earth grounds (e.g., one for the AC service and another for the radio) creates ground loops , which can introduce hum and invite lightning surges into the shack. The Foundation: Grounding vs
is the act of connecting all conductive parts together to ensure they stay at the same electrical potential. The goal is to minimize voltage differences between pieces of equipment, which prevents destructive arcs during lightning strikes and reduces RF noise. 2. Power Systems and AC Safety
