- What does RST stand for in amateur radio?
Show answer
Readability, Strength, Tone
- What is a contest exchange?
Show answer
The minimum required information exchanged during a contest QSO, typically call sign, RST report, serial number, and contest-specific data
- What is a serial number in a contest exchange?
Show answer
A sequential number assigned to count each QSO made by a station during the contest
- What is a multiplier in a contest?
Show answer
A countable factor beyond QSO count used to calculate score, such as states, countries, or zones worked
- What does DX mean in ham radio?
Show answer
Distance, or long-distance communication, typically international or intercontinental
- What is a QSL card?
Show answer
A postcard confirming a radio contact, sent between operators to verify communication took place
- What is a DXpedition?
Show answer
An expedition by operators to a rare or remote country to operate from that DXCC entity and make contacts worldwide
- What is a pile-up in DX operating?
Show answer
A situation where many stations attempt to contact a rare or desirable DX station simultaneously, creating RF chaos
- What is a DXCC entity?
Show answer
A country or territory counted separately for the DXCC (DX Century Club) award, based on political or geographic divisions
- What propagation mode allows long-distance HF communication via the F-layer?
Show answer
Skywave propagation, enabling ionospheric reflection for intercontinental contacts
- What does the solar flux index predict?
Show answer
Ionospheric conditions and HF propagation quality, higher values generally indicate better propagation
- What does the K-index measure?
Show answer
The level of geomagnetic disturbance, used to predict HF propagation (higher K-index indicates worse propagation)
- What is a DX window?
Show answer
A time period designated by contest rules or DXing etiquette during which a band is primarily for DX activity
- What is a DXcluster?
Show answer
A network system used to spot and share information about rare DX stations and propagation conditions in near real-time
- What is the Cabrillo format?
Show answer
A standardized plain-text file format for submitting amateur radio contest logs to contest organizers
