3.1 Contest bands and segments

The following bands will be used for this contest: 160M, 80M, 40M, 20M, 15M, 10M. Avoid interference with other modes or contests running in the same weekend.
The contest frequencies for FT8 modes will not be the usual for these protocols, but somewhat higher in frequency. The transceiver dial frequencies that will be used for FT8 are: 1,843 – 3,577 -7,077 – 14,077 – 21,077 and 28,077 MHz.
For FT4 the standard frequencies for FT4 can be used.

3.2 Entries are separated in “World” and “the Netherlands”.

4. Division ranking

4.1 Dutch VERON members can put the number and optionally the name of their division (not the QSL region) in the Cabrillo log “Club tag” like: CLUB: 35 or CLUB: 01 Alkmaar
The sum of the single operator and SWL operator scores of a division will give the divisional score.

5. General Rules

5.1 The transmitter and receivers must be located within a 500-meter diameter circle. All antennas used by an entrant must be physically connected to the transmitter or receivers by wires (cables or feedlines).

5.1.1 All categories of entrants can use packet and WEB clusters.

5.1.2 Self-spotting is not allowed during the contest.

5.1.3 Using other stations callsigns to keep the working frequency free on the other bands, making schedules or DX-spotting is prohibited.

5.2 Single operator participants may change bands and modes without restrictions. Only one signal can be transmitted at any given time.

5.2.1 Single Operator: Those stations at which one (1) person performs all of operating, logging, and spotting functions.

5.3 MOST stations can transmit only one signal on any band at any given time. A “multiplier” station is allowed if there is an interlock ensuring only one signal at any given time.

5.3.1 In the MOST category, the RUN station is allowed to change bands only once every 10 minutes. Violating this rule will make that the QSO’s made in the non-regular time will be discarded.

5.3.2 The log must indicate which transmitter made each QSO (according to the CABRILLO standard).

5.4 Each station can be worked once in RTTY and once in FT8 on each band.

5.4.1 The use of software functions that allow two or more QSOs on the same moment are forbidden (Multi Answer, FOX-Hound, etc.)

5.4.2 The use of a QSO robot is strictly prohibited. The operator must operate the equipment during the QSO.

5.4.3 The use of a remote SDR station is not allowed.

6. Exchange

6.1 Dutch stations (PA): signal report (RST) + 2 position province abbreviation. GR, NB etc.

World: RST + serial number starting with 001

7. QSO Points

7.1 Each valid contact with another participating contest station is worth one (1) point, a QSO with a Dutch station 3 points.

7.2 For a SWL station each heard RTTY PACCdigi contest station (both Dutch (PA) and non-Dutch (Non-PA)) counts as 1 point. Every callsign counts once per band. Heard FT8 QSO’s will not provide any contest points.

7.3 A contest station may not be logged more than 10 times per band.

8. Dupes

8.1 Dupes are contacts made with the same station on the same band. If the first contact between stations is valid, dupes have a 0 points value. If the first contact is not valid, the second (dupe) contact is accepted.

8.2 Dupe contacts are not penalized; one does not have to mark them in the Cabrillo log submission.
Moreover, entrants are strictly recommended to leave DUPES in the log file. DO NOT DELETE DUPES!

9. Multipliers

9.1 A multiplier of one (1) for each worked different Dutch Province. Every Province can be worked in RTTY as well as in FT4/FT8. So, the maximum number of multipliers on each band is 24.

9.2 The abbreviations for the Dutch Provinces are: NH, ZH, ZL, NB, UT, FL, FR, GR, OV, DR, GD, LB
Contacts with Dutch maritime mobile (/MM) don’t count as a multiplier.

10. Final Score

The final score is the sum of all qso points multiplied by the sum of all multipliers (band and mode).

16. Penalties

  •  One QSO is penalized with 1 QSO point for the following:

– Incorrectly logged calls.

– Not logging the exchange of the opposite QSO partner.

– One QSO is not present in the other station’s log. A close similar call sign, giving evidence of a miscopy by the other station, could not be found in the other station’s log (NIL).

  • QSO neither counted nor penalized for the following:
    – QSO time in entrant’s log and other station’s log difference is more than 5 minutes (except systematic computer errors).
    – QSO band or mode in entrant’s log and other station’s log differ.

    -Dupe QSO which is not in the other station’s log.

    – The other station is obviously not a contest participant (‘001’ exchange in multiple logs, other exchanges not found).

  • One QSO which is a UNIQUE (not in the database and cannot be related to a possible miscopy) will get normal credit. The Contest Manager will further check logs of stations with a far above average percentage of UNIQUES.

16.1 PACCdigi Contest manager decisions are final. PACCdigi Contest manager invites all the radio amateurs from the Netherlands and foreign countries to take part in the 2024 PACCdigi Contest.
