ARRL DXCC ENTITY RE-EVALUATION MEMORANDUM – 3B7

3B7 — AGALEGA & ST BRANDON ISLANDS
Evaluation Under 1960 ARRL DXCC Rules

I. PURPOSE

This memorandum evaluates whether 3B7 — Agalega & St Brandon Islands qualified as a separate ARRL DXCC Entity under the 1960 ARRL DXCC Rules, which governed DXCC administration during the early post-war expansions of the list.

The evaluation includes:

• 1960 political-entity criteria (sovereignty, colonial administration, distinct governing authority)
• Geographic and “dependency island group” criteria
• Separation from the parent entity Mauritius (3B8)
• Distinct administrative identity within the British colonial framework
• 1960 DXCC interpretive practice for remote island dependencies

Agalega & St Brandon were recognized in the “3B” block as administratively separate from Mauritius and Rodrigues.

II. BACKGROUND

Political & Administrative Status (as of 1960)

• In 1960, Mauritius—including Agalega, St Brandon, and Rodrigues—was a British Colony: The Colony of Mauritius.
• Within this structure:
– Agalega was administered by a private company under concession, with semi-autonomous local administration.
– St Brandon (Cargados Carajos) was managed by fishing companies under long-term leases, with separate administrative oversight from Mauritius.
• Both groups were recognized by the colonial administration as outer island dependencies, not part of the contiguous settled island of Mauritius.

Geographic Characteristics

• Agalega Islands lie ~700 miles north of Mauritius.
• St Brandon Islands lie ~260 miles northeast of Mauritius.
• Both archipelagos are:
– Isolated
– Geographically distinct from Mauritius
– Not connected by reefs or continental shelf
– Sparse or seasonally inhabited
• The islands are composed of:
– Agalega: two elongated islands
– St Brandon: >50 sand cays and islets spread over a shallow bank

DXCC Prefix

• Use 3B7, assigned to Mauritius’ “outer island groups” under the broader 3B prefix family:
– 3B6/7 (Agalega & St Brandon)
– 3B8 (Mauritius)
– 3B9 (Rodrigues)

DXCC History

• The 3B region was subdivided early into three separate DXCC Entities:
– 3B8 Mauritius
– 3B9 Rodrigues
– 3B6/3B7 Agalega & St Brandon
• Subdivision reflected 1960 ARRL practice of recognizing administratively distinct, geographically remote island dependencies.

III. ANALYSIS UNDER THE 1960 DXCC RULES

The 1960 DXCC Rules recognized DXCC Entities in three categories:

Political Entities
Dependencies with clearly separate administration
Geographically separate island groups with no physical connection to parent territories

The 1960 Rules did not yet include the later 100-mile rule, but DXCC practice followed DeSoto’s 1935 “discrete entity” concept plus recognition of administratively separate dependencies.

1. POLITICAL ENTITY CRITERIA (1960)

1(a) Sovereignty — FAIL

• Agalega and St Brandon were not sovereign; they were dependencies of the British Colony of Mauritius.

1(b) Distinct Government — PARTIAL

• Agalega had local administrative authority under corporate concession.
• St Brandon had independent management structure separate from Mauritius civil administration.
• However, both remained under ultimate colonial authority.

1(c) International Recognition — FAIL

• Neither island group had separate international or diplomatic standing.

Conclusion:
Agalega & St Brandon cannot qualify as Political Entities under 1960 rules.

2. GEOGRAPHIC / DEPENDENCY CRITERIA (1960)

This is the core of their qualification.

The 1960 Rules allowed recognition of remote island dependencies where:

The islands were geographically distinct and significantly separated from the parent colony.
The islands had separate administrative or dependency status within the colonial government.
The group formed a coherent archipelago outside the main island.
The DXCC Program had long recognized similar cases (e.g., CE0 Chilean dependencies, FJ Saint Barthélemy, VP6 Pitcairn).

Applying these:

2(a) Islands above high tide — ✔ PASS

• Both groups contain multiple permanently exposed landmasses.

2(b) Significant geographic separation — ✔ PASS

• Agalega is ~700 miles from Mauritius—far greater than typical dependency separations of the era.
• St Brandon is ~260 miles from Mauritius—still substantial for 1960 DXCC practice.
• Neither island group sits on Mauritius’ shallow coastal platform.

2(c) Distinct dependency administration — ✔ PASS

• The colonial government treated Agalega and St Brandon as outer dependencies, not as part of the main Mauritius district administration.
• Each had separate governance mechanisms and lease/concession frameworks.

2(d) Precedent for remote island entities — ✔ PASS

1960 ARRL practice recognized:
• CE0 Chilean offshore dependencies
• FR/G Glorioso
• FT/W Crozet
• ZD7 St Helena
• VP2/VP5 Caribbean dependencies
• VK9 external Australian islands
Agalega & St Brandon fit this established pattern.

2(e) Distinct identity within DX usage — ✔ PASS

• The region had historical amateur operation distinct from 3B8 and 3B9.

Conclusion:
Agalega & St Brandon fully satisfy the 1960 geographic/dependency criteria.

3. SPECIAL-AREA CRITERIA (1960)

No special-area categories existed.
Not applicable.

4. 1960 DELETION CRITERIA — NOT TRIGGERED

Deletion required:

Proof that an entity never met original criteria, or
A political change merging it into another entity.

In 1960:
• Geographic separation existed
• Administrative separation existed
• DXCC intentionally recognized the group
• No political merger had occurred

Thus the deletion rule was not triggered.

V. FINAL DETERMINATION

✅ 3B7 — Agalega & St Brandon Islands qualify as an ARRL DXCC Entity under the 1960 DXCC Rules.

Qualification basis (1960):

✔ Clear and substantial geographic separation from Mauritius
✔ Distinct administrative and dependency status within the Colony of Mauritius
✔ Recognized as “outer dependency island groups” under British colonial governance
✔ Consistent with ARRL recognition of similar remote dependency islands in 1960
✔ Satisfy island-exposure, distinct-archipelago, and administrative-separation criteria
✔ DXCC precedent for remote dependency island entities strongly applicable

Conclusion:
Under the 1960 ARRL DXCC Rules, Agalega & St Brandon were properly recognized as a separate DXCC Geographic/Dependency Entity (3B7).
