Please listen carefully before calling and follow the operators’ instructions. Split operation may be used whenever required to maintain an efficient and well-organised pile-up.

We will also attempt activity via the QO-100 satellite whenever possible.

Split operation will be used at all times. Please ensure your transceiver is correctly configured before calling and carefully follow the operator’s instructions.

Typical split ranges:
CW: up 1–5 kHz
SSB: up 5–15 kHz
RTTY: up 3–10 kHz

For FT8 operation, the MSHV software (2 to 6 slots) will be used on the announced frequency. Stations should call in normal mode and remain on their own transmit frequency.

Please do not transmit on our calling frequency. QSOs will be confirmed and logged on our server once RR73 or 73 is sent.

Confirmation

QSL Policy

QSL information will be announced by the team. Please check the official channels for direct QSL, bureau, LoTW and online log confirmation details.

Operators are kindly requested to avoid duplicate QSOs and to verify their contacts through the online log when available.
