ARRL DXCC ENTITY RE-EVALUATION MEMORANDUM – D4

D4 — CAPE VERDE
Evaluation Under 1975 ARRL DXCC Rules

I. PURPOSE

This memorandum evaluates whether D4 — Cape Verde qualified as a separate ARRL DXCC Entity under the 1975 ARRL DXCC Rules, the criteria governing DXCC classification during the major post-colonial restructuring of the world political map.

Evaluation covers:

• Cape Verde’s political status in 1975
• Whether it met the DXCC Political-Entity criteria
• International recognition and sovereignty
• National prefix and telecommunication independence
• Applicability of deletion criteria

Cape Verde appears on the DXCC List under the D4 prefix block.

II. BACKGROUND

Political & Administrative Status (Pre-1975)

Prior to independence, Cape Verde was:

• A Portuguese Overseas Province, not a colony
• Administered from Lisbon
• With no separate sovereignty
• Not recognized internationally as independent

Political Transformation (1975)

On 5 July 1975, Cape Verde became:

• The independent Republic of Cape Verde
• With:
– A sovereign constitution
– Independent executive, legislative, and judicial branches
– Full control of territorial governance
– Its own foreign policy and diplomatic representation

International Standing (1975)

After independence, Cape Verde was:

• Recognized by Portugal and other major world governments
• Admitted to the United Nations in 1975
• Listed in all international diplomatic records as a sovereign African nation
• Engaged in formal bilateral relationships with numerous states

DXCC Prefix Identity

• “D4” was allocated as Cape Verde’s national telecommunication prefix block
• Demonstrates independent national radio regulation
• Consistent with prefix practices for newly independent Lusophone states (D2 Angola, D3 Angola, D6 Comoros)

DXCC Context (1975)

The 1975 ARRL DXCC Rules recognized:

Political Entities as:

Sovereign independent nations, OR
Administratively separate territories with distinct governance, OR
UN-recognized non-self-governing territories

Cape Verde fits Category 1 exactly.

Geographic Entities as:

• Islands ≥100 miles from parent
• Entities separated by another DXCC Entity
• Special cases (Antarctica, etc.)

Cape Verde is a sovereign nation, so the geographic tests are irrelevant.

III. ANALYSIS UNDER THE 1975 DXCC RULES

1. POLITICAL ENTITY CRITERIA (1975) — PASS

1(a) Sovereign Independent Nation — ✔ PASS

• Independence formally achieved 5 July 1975
• No continued Portuguese sovereignty
• Cape Verde assumed full territorial control

1(b) Independent Government — ✔ PASS

• Established constitution
• National ministries and civil administration
• Independent judiciary and legislature
• Self-governing in all respects

1(c) International Recognition — ✔ PASS

• Quickly recognized by the UN
• Diplomatic recognition by Portugal, Africa, Europe, and worldwide
• Participation in international organizations

1(d) Distinct ITU Prefix & Telecommunications Authority — ✔ PASS

• Assigned D4 prefix block
• Independent national licensing and regulation
• Fully meets DXCC prefix identity criteria

Conclusion:
Cape Verde satisfies all 1975 Political-Entity requirements completely.

2. GEOGRAPHIC ENTITY CRITERIA (1975) — NOT REQUIRED

Cape Verde is a sovereign state; therefore:

• The 100-mile offshore-island rule does not apply
• Intervening-entity rules do not apply
• Island-group tests do not apply

Its DXCC qualification is political, not geographic.

3. SPECIAL-AREA CRITERIA (1975) — NOT APPLICABLE

Cape Verde was not:

• A UN trust territory
• A mandate
• A protectorate
• An Antarctic region

Thus §III has no bearing.

4. 1975 DELETION CRITERIA — NOT TRIGGERED

Deletion required:

Loss of sovereignty, OR
Absorption into another state

Neither applied:

• Cape Verde’s sovereignty was newly established and remained intact
• No merger into another nation occurred
• No administrative dependency reintroduced

Thus deletion is impossible.

V. FINAL DETERMINATION

✅ D4 — CAPE VERDE qualifies as an ARRL DXCC Entity under the 1975 DXCC Rules.

Qualification Basis (1975):

✔ Newly independent sovereign nation (1975)
✔ Internationally recognized and admitted to the UN
✔ Independent civil administration and national governance
✔ Unique national prefix block (D4)
✔ Fits the 1975 DXCC Political-Entity definition perfectly
✔ Entirely consistent with DXCC treatment of post-colonial states (D2 Angola, 3C Equatorial Guinea, 9G Ghana, 5H Tanzania, etc.)

Conclusion:
Under the 1975 ARRL DXCC Rules, D4 — Cape Verde qualifies clearly, fully, and directly as a Political DXCC Entity.
