Operating Terms
General amateur operating vocabulary — DX and pileup terms, contest basics, POTA/SOTA activating, and traffic/net procedure.
The same term, "Activator," is used by both POTA and SOTA for this role — but the term for the other side of the contact differs…
Break-in Break-in (full vs. semi)เบรกอิน (แบบเต็มรูปแบบ vs. กึ่งหนึ่ง)See the QSK entry for the full-break-in-specific term and its history. Semi break-in is far more common on typical amateur transc…
Calling frequency Calling frequencyความถี่เรียกCommon on VHF/UHF (e.g. a national or regional simplex calling frequency) and in some HF contexts. Keeping calling frequencies cl…
Callsign CallsignสัญญาณเรียกขานAlways send/say your full callsign, not just a suffix — required practice in most countries and directly tied to legal station id…

Check-in Check-in (to a net)เช็คอิน (เข้าร่วมเน็ต)On a CW traffic net, checking in is done with QNI. On a casual phone net, it's usually as simple as giving your callsign and name…

Multiplier Multiplierตัวคูณคะแนน (Multiplier)What counts as a multiplier is entirely defined by each contest's rules — commonly DXCC entities, US states, CQ zones, or grid sq…
NCS Net Control StationNet Control Station (NCS)On a formal CW traffic net, the NCS is the only station authorized to use certain QN signals (marked with an asterisk in ARRL's o…
Net Net (organized on-air group)เน็ต (กลุ่มออกอากาศแบบมีการจัด)Nets range from formal CW traffic nets using QN signals, to relaxed weekly phone roundtables. See Net Control Station (NCS) and C…

Pileup Pileupไพล์อัพ (สถานีเรียกพร้อมกันจำนวนมาก)Working a pileup well is a real operating skill — listening, timing your call correctly, and following the DX station's instructi…
QSO rate QSO rateอัตราการติดต่อ (QSO rate)Contesters watch their rate closely during an event; a strong "run" on a clear frequency typically produces a much higher rate th…
Run Running (contest strategy)Run (กลยุทธ์เรียก CQ ต่อเนื่อง)The counterpart strategy to Search & Pounce. A station with a strong signal and a clear frequency can often "run" a fast rate of…
SOTA Summits on the AirSummits on the Air (SOTA)Each qualifying summit has its own reference number and point value based on height/prominence. As with POTA, program-specific ru…
