4. Entry Categories


4.1 Single Operator

Single operator means that one single person performs all operating, logging and spotting functions. There is no limit in band changes. Only one transmitted signal is permitted at any time.

  • Single Operator All Band – High Power: Total output power must not exceed 1500 watts
  • Single Operator All Band – Low Power: Total output power must not exceed 100 watts
  • Single Operator All Band – QRP: Total output power must not exceed 5 watts
  • Single Operator Single Band – Scandinavians only – 80, 40, 20, 15 or 10 meter. Total output power must not exceed 1500 watts
  • Single Operator Low Band – Non-Scandinavians only – 80 and 40 meters. Total output power must not exceed 1500 watts

4.2 Multi Operator Single TX – All Band (MULTI-ONE)

This category is for all participants. Only one signal may be transmitted on any band at any time (running station). When operation has started on one band, the station must remain on that band for at least 10 minutes. The 10-minute period starts with the first QSO worked on that band.
Exception: It is allowed to work a QSO on another band if it is a new multiplier (multiplier station). The multiplier station is allowed to be on the air at the same time as the running station. The multiplier station may not solicit contacts by calling CQ, but may ask stations during the multiplier QSO to move to another band where the multiplier is needed. The log must indicate which station/signal (run or multiplier) made each QSO. Total output power of each transmitted signal must not exceed 1500 watts

4.2 Multi Operator Multi TX – All Band (MULTI-MULTI)

This category is only for Scandinavian stations. There are no restrictions on the number of transmitters. Only one signal per band is allowed at any time. Total output power of each transmitted signal must not exceed 1500 watts

4.3 Overlay

Single Operator All band entrants may also participate in one of the overlay categories by adding the CATEGORY-OVERLAY: ROOKIE, CLASSIC, TB-WIRES or WIRE-ONLY in their Cabrillo log file. Overlay category entries will be listed separately in the results. They are scored only as All Band entries and grouped by High Power and Low Power (includes QRP).

ROOKIE overlay must be licensed for the first time less than 3 years before the actual contest starts.

CLASSIC overlay may not use any assistance at all. No cluster and no devices showing call signs and frequencies of other participants.

TB-WIRES overlay shall use only one triband antenna with a single feed line from the transmitter to the antenna for 10, 15 and 20 meters, and simple wire antennas for 40 and 80 meters.

WIRE-ONLY overlay shall use the same single wire antenna for all bands.

4.4 CHECKLOG

Entry submitted to assist with the log checking. The entry will not have a score in the results and the log will not be made public.

4.5 EXPLORER

Read the EXPLORER rules supplement, below.

4.6 Station Location

All transmitters and receivers must be within a single 500-meter diameter circle. Antennas must be physically connected by RF transmission lines to the transmitters and receivers.

4.7 QSO finding assistance

The use of DX-Cluster, Skimmer, and Skimmer-like technology (such as Reverse Beacon Network) is allowed for all categories except CLASSIC overlay. Self-spotting or requesting stations to announce one’s own call on the DX-Cluster is NOT allowed.

5. Frequencies to be used

  • CW : 3510-3560, 7000-7040, 14000-14060, 21000-21070, 28000-28070 kHz
  • SSB: 3600-3650, 3700-3800, 7060-7100, 7130-7200, 14125-14300, 21151-21450, 28320-29000 kHz.

According to the IARU Region-1 HF Bandplan.

6. Contest exchanges

The contest exchange consists of RS(T) plus serial number sequence starting with 001 (e.g., 59(9) 001). QSO’s after 999 are numbered 1000, 1001, etc. Stations in the Multi Operator category may use separate serial number sequences on each band. The same station may be worked once on each band. Cross-mode and/or cross-band QSO’s are not allowed.

7. Scoring

A QSO with correct callsign and exchange counts for QSO points.

7.1 For Scandinavian stations:

  • EUROPEAN stations, outside Scandinavia, are worth two (2) points for every complete QSO.
  • NON-EUROPEAN stations are worth three (3) points for every complete QSO.

7.2 For non-Scandinavian stations:

  • EUROPEAN stations receive one (1) point for every complete Scandinavian QSO.
  • NON-EUROPEAN stations receive one (1) point for every complete Scandinavian QSO on 14, 21, and 28 MHz and three (3) points for every complete QSO on 3.5 and 7 MHz.

8. Multipliers

8.1 For Scandinavian stations

Each worked DXCC entity is valid as one multiplier for each band.

8.2 For non-Scandinavian stations

Each worked prefix-number (Ø-9) in each Scandinavian DXCC entity is valid for one multiplier on each band (e.g. SI3, SK3, SL3, SM3, 7S3, and 8S3 all count for the same (1) multiplier). Stations without a prefix number count for the 0th area (e.g., LA/G3XYZ counts for LAØ), and those with two or more prefix numbers counts for the area indicated by the first number (e.g., OZ150A counts for OZ1).

9. Final score

To calculate the final score, multiply the sum of QSO points on all bands with the sum of multipliers worked on all bands.

10. Logs

By submitting a log, you agree that your log and the corresponding log checking report may be made open to the public. Use the CABRILLO format. Find the Cabrillo template under the Rules menu https://www.sactest.net/blog/rules/cabrillo-3-0/. Please ensure that you fill out all of the header information, including a possible category overlay as indicated in §4.3 above. Leave all your QSOs in the log, dupes included. The log checking software will find the dupes and mark them with zero points. Participants aiming for a top-three score should include the exact frequency of every contact in the log. Electronic submission of logs is required for all entrants. Logs are uploaded on https://www.sactest.net/robot/

11. Closing date for logs

Cabrillo logs shall be uploaded no later than 5 days after the end of the contest, at 23:59 UTC . Logs submitted after the deadline will be listed as checklogs.

SAC Category Explorer 2023

With the EXPLORER Category we want to encourage you to do experiments in the way you participate in contests. It can be the way you use remote receivers, internet links, video transmissions and it also includes some new thinking in hardware design like filters, clean signals, TX interleaving, remote controlling and log program innovations. In this way you may participate in the SAC Contest while experimenting creatively with stations linked in any way, Multi-signal transmissions and other new technologies. The Category is for both Scandinavians and non-Scandinavians.

The EXPLORER category is intended to encourage innovation in technology adaptation, station design, new technology development and operating strategies. Rules for all participants are the same as the standard rules (date, time, modes, exchange) – with the following additions:

E1. Entry Category-Operator

  • Single-operator: only one licensed radio amateur performing and supervising all operating and logging functions.
  • Multi-operator: multiple operators perform or supervise all operating and logging functions. Members of a multi-operator team are permitted to operate from different locations.

E2. QSO-alerting

QSO-alerting assistance and QSO solicitation: The use of QSO-alerting assistance IN ANY WAY is permitted in both categories. Self-spotting or asking to be spotted is permitted. All contacts must be accomplished over the air (Audio recording).

E3. Locations

All entries may use multiple transmitting and/or receiving sites. Remote receiving sites may be located anywhere. All cross-border remote operations must comply with the regulations in the country where the transmitting site(s) is/are located.

E4. Log Submission

Log Submission: Logs must be uploaded at https://www.sactest.net/robot/
Logs must be in Cabrillo standard format and include the lines:
CATEGORY-STATION: EXPLORER
CATEGORY-OPERATOR: [SINGLE-OP or MULTI-OP]

E5. Audio Files

Each participant must (on demand) deliver a full 24 hour Audio file recording of the “On Air Communication” for every logged QSO. The audio streams must include both received audio and sent audio. Each participant may deliver the audio file if their entry would assume such and make its details more presentable…..
The files must be in mp3 format

E6. Station Description

A detailed description and pictures of equipment and operation is extremely welcome. The SAC contest committee will find the most innovative station and award this with a special prize.

E7. Awards

The winning entry in each of the two categories will receive a special EXPLORER Plaque. In addition, entries demonstrating a significant amount of innovation may receive special prize at the discretion of the SAC Contest Committee.
