The 350-kilometer (approximately 220-mile) separation threshold introduced in 1960 was retained, but additional guidance was provided to address previously ambiguous cases.

II. Eligibility Requirements

• Open to all licensed amateur operators worldwide.

• All contacts must be two-way amateur QSOs conducted under lawful authorization.

• Contacts made after November 15 1945 qualify for credit.

• Any amateur band or authorized mode may be used.

• All contacts for a given application must originate from a single DXCC country.

---

III. Confirmations

• Each claimed country must be supported by a QSL card showing: callsigns, date, time (GMT), band, mode, and station location.

• Cards must be verified by ARRL Headquarters or an authorized DXCC Field Representative.

• Duplicate QSOs with the same country do not increase totals.

IV. Qualification for Award

• Confirmation of 100 countries qualifies for the DX Century Club Certificate.

• Endorsements issued for higher totals (125, 150, 200, 250, 300, etc.).

• “Single-Band” and “All-Band” DXCC accomplishments recognized.

• Recipients listed in QST and the annual ARRL DXCC List.

V. Maintenance of the DXCC List

“

The Awards1961 Committeerules shallcontinued reviseto vest authority for maintaining the DXCC List in the ARRL Awards Committee, with revisions implemented as political or geographic changes occur, or when new information becomes available. Additions or deletions become effective as of the date published in QST.”

Notable 1961 additionsoccurred and changes:

• Newly independent African nations added (e.g., Nigeria, Cameroon, Somalia).

• Adjustments to Pacific island groups (clarifying boundaries for Lord Howe, Norfolk, and Cocos entities).

• Separation of French Somaliland and Aden as distinct entities under Rule 1B.

VI. Determination of Borderline Cases

“All questions as to the qualification of an area as a DXCC country shall be determined by the ARRL Awards Committee, whose decisions shall be final.”

VII. Publication and Recognition

• Award recipientsformally published in QST. The publication-based implementation process introduced earlier was now firmly established as the standard mechanism for updating the list.

Determination

of Borderline Cases

AllThe 1961 rules reaffirmed the ARRL Awards Committee’s role as the final authority in determining DXCC entity qualification, maintaining continuity with earlier editions. However, the clarifications introduced in this revision significantly reduced the scope of ambiguity in many borderline cases, particularly those involving offshore islands and intervening territory.

The addition of explicit guidance—such as the great-circle path test and the 50-kilometer island grouping rule—provided more objective tools for resolving geographic questions that had previously been subject to interpretation. Similarly, the requirement for recognized communications authority in administrative cases helped standardize decisions involving dependencies and territories.

Despite these improvements, the system remained inherently hybrid. While many scenarios could now be resolved through clearer rule application, the continued presence of exceptional cases and the need to reconcile new criteria with existing precedent ensured that administrative discretion remained an integral part of the Awardsdecision-making Committee are final.process.

Historical Significance
