SWL Logs should show in columns:





Callsign of "Station Heard",

complete exchange report sent by this station,


Callsign of station being worked,


a RS(T) report on "Station Heard" at SWLs QTH,


points and multiplier.


If both sides of a contest contact are heard, they may be claimed as separate stations and the callsigns have to appear in the "Station Heard" column. A station may only appear once per band as station heard. In the column "Station Worked" the same station may not be logged more than Five (5) times per band.


As stipulated in the regulations governing the license of the transmitting station.


RS(T) report plus serial number starting with 001 and increased by One (1) for each successive contact.


SEANET stations may contact all stations.

Rest of the World Stations may only contact SEANET Stations.

SWL’s may Log in all Stations participating during the SEANET Contest.

For this contest, a SEANET Station is defined as one operating from the following DXCC Country / Entity:

4S, 4W, 8Q, 9M/DX0 (Spratly), 9M2, 9M6/8, 9N, 9V, A5, BS7, BV, BV9P, BY, DU, H4, HL/DS, HS/E2, JA, JD1/M, JD1/0, KH0, KH2, P2, P5, S2, T8, V6, V8, VK, VK9C, VK9X, VR2, VU, VU4, VU7, XU, XV/3W, XW, XX9, XY, YB.


Valid QSOs count 1 Point.

Only one contact is allowed on each band with the same station (not one contact on each mode).


  1. SEANET Stations & SWL: Claim one multiplier for each DXCC entity worked on each band including those in the SEANET region and in their own country.
  2. Rest of the World Stations & SWL: Claim only one multiplier for each DXCC entities within the SEANET region (see the entity list above). Each multiplier counts once on each band and not mode. QSO points can be claimed for QSOs with the same station on different bands.

Score: Total number of QSO points multiplied by the total number of multipliers worked.


  • Contacts on cross modes or cross bands will not count.
  • Operators are not allowed to transmit more than one signal at any one time.
  • Entries that contain errors or unmarked duplicates will receive a reduction of points.
  • Any contestant who uses methods contrary to the spirit of the contest may be subject to disqualification.
  • All stations may use Internet or Packet Cluster "Spotting". Multi-band, multi-operator stations must not use more than one transmitter / transceiver at the same time for contacts, except that a second receiver / transceiver may be used for "spotting" only. The "spotting" station must not transmit or make any kind of contact.
  • The decision of the SEANET contest organizers shall be final.


Logs may be either hand-written or computerized and must contain a summary sheet that specifies the Category Entered.


Information required for each contact shall include:


Time (UTC)


Mode (CW / SSB)

Report Sent (RS[t])


Serial Number

Report Received (RS[t])

Serial Number

Claimed Multiplier


Duplicates should be logged, but marked clearly as duplicates (“Dupes”) and scored at zero points.

Both hand-written and computerized logs must be accompanied by a Summary Sheet listing the number of claimed contacts and multipliers per band, the final score and a declaration that the station was operated within the terms of the station license and the rules and spirit of the contest.

Computer logs and Summary Sheets must be in ASCII (text) format including Cabrillo. Please do not send (.bin) files.

It is recommended that entries be made in any standard contest logging program in the ARRL DX contest mode and then scored manually. Manual scoring is simply the number of valid QSOs multiplied by the total number multipliers. Almost every contest logging program supports the ARRL DX Contest and using this contest format allows the received serial number to be easily logged in place of the received power level. If you do not already have a contest logging program you may download CT by K1EA free of charge from
