What is this page about?
This page explains what simplex operation is, how it differs from repeater operation, and why it remains important in amateur radio.
Why Simplex Matters
- Works without infrastructure
- Useful for nearby communication
- Important in emergencies
- Helps operators understand direct radio range
Simplex vs Repeater Operation
In repeater operation, a central system retransmits the signal. In simplex operation, the radios communicate directly with each other.
Practical Considerations
Simplex range depends on terrain, antenna height, power level, and environmental conditions.
