ARRL DXCC ENTITY RE-EVALUATION MEMORANDUM – BS7H

BS7H — SCARBOROUGH REEF
Evaluation Under 1995 ARRL DXCC Rules

I. PURPOSE

This memorandum evaluates whether BS7H — Scarborough Reef qualifies as a separate ARRL DXCC Entity under the 1995 ARRL DXCC Rules, the criteria in effect when ARRL added Scarborough Reef to the DXCC List on 1 April 1995.

The evaluation considers:

• 1995 Geographic Separation Criteria (100-mile rule)
• Political-entity criteria under Rule 1(a) and 1(b)
• Recognition of Scarborough Reef as a dependency of China (PRC)
• Territorial isolation and non-self-sustaining nature
• Precedent for uninhabited offshore reefs and rocks
• Applicability of deletion rules under the 1995 DXCC List policy

Scarborough Reef was added in 1995 exclusively as a Geographic Entity (offshore island/reef group), not as a political entity.

II. BACKGROUND

Geographic and Physical Characteristics

• Scarborough Reef is a small atoll consisting of four large rocks permanently above water at high tide
• Located in the South China Sea
• No permanent population
• No independent administration
• No resource base; unsuitable for sustained habitation

Coordinates (approx.):
• 15°07′N 117°45′E

Political Status in 1995

• Claimed by China (PRC)
• Also claimed by the Philippines
• In 1995, the ARRL used the de facto administrative claim standard for dependencies
• Despite the international dispute, ARRL listed Scarborough Reef as a Chinese dependency (“BS” prefix block) for DXCC purposes

DXCC History

• Added 1 April 1995 as a new Geographic Entity
• Qualification based on island/reef separation under the 1995 Rules
• First BS7H DXpedition: 1995 (the activation that resulted in its recognition)

III. ANALYSIS UNDER THE 1995 DXCC RULES

Under the 1995 DXCC Rules, an Entity could qualify by either:

(1) Political Entity Rules

(2) Geographic Entity Rules

Scarborough Reef did not qualify as a political entity, so the case rests entirely on the Geographic Entity criteria.

1. POLITICAL ENTITY CRITERIA (1995)

Rule 1(a): United Nations Membership — FAIL

• Scarborough Reef is not a sovereign state
• No UN membership or separate diplomatic status

Rule 1(b): Internationally Recognized Sovereign Nation — FAIL

• Scarborough Reef is not a sovereign nation
• Subject to competing claims between China and the Philippines

Rule 1(c): Distinct Administration — FAIL

• No indigenous government or civil authority
• Administered (for ARRL purposes) as part of China, but with no distinctive political administration
• Non-qualifying under any political path

Conclusion: Scarborough Reef clearly fails all political-entity paths under the 1995 rules.

2. GEOGRAPHIC ENTITY CRITERIA (1995)

Scarborough Reef was added solely under this section.

The 1995 ARRL DXCC Rules contained the classic 100-mile rule:

Rule II: Separate Entity status may be conferred when:

“A separated island, island group, or reef is located at least 100 miles from the nearest point of its parent political entity.”

For dependencies or territories of a DXCC parent, an entity must be:
• Separated by at least 100 miles, AND
• Be part of a recognized administrative dependency of that parent

1995 Geographic Data

• Distance from Scarborough Reef to mainland China: far greater than 100 miles
• Distance to the nearest other Chinese DXCC Entity (Hainan Island) also exceeds 100 miles
• Scarborough Reef is a reef group with at least four points permanently above water

Does Scarborough Reef satisfy the 100-mile rule?

✔ YES — PASS

The reef lies:
• ~400+ miles from Hainan
• ~550 miles from Guangdong
• >100 miles from all components of the “China” DXCC Entity
• >100 miles from any other DXCC Entity

Thus Scarborough Reef fulfills the separation requirement substantially, not marginally.

Definition Check: “Reef” as a Qualifying Feature

The 1995 rules explicitly allowed:

“Island, island group, reef, or rock that is permanently above water at high tide.”

Scarborough Reef satisfies this.
The four major rocks meet the high-tide permanence requirement.

Administrative Linkage Requirement

For offshore-island entities:
• Must be attached administratively to a parent DXCC Entity
• ARRL accepted the PRC’s claimed jurisdiction in 1995
• Therefore the reef was classified as a Chinese dependency

Conclusion:
Scarborough Reef fully satisfied the Geographic Entity criteria under the 1995 rules.
This was the sole basis for its addition.

3. SPECIAL-AREA CRITERIA (1995)

Not applicable.
Scarborough Reef is not:
• Antarctic
• International zone
• Special political area
• Historical exception

4. DELETION CRITERIA UNDER THE 1995 RULES

Deletion occurs only if:

An entity loses all criteria under which it qualified, OR
Its political status changes such that its classification was in error.

For Scarborough Reef:

• It still exists physically
• It still meets island/reef permanence definitions
• It is still >100 miles from China
• It still qualifies under the same Geographic criteria

While political control is disputed today, the 1995 rules accepted PRC administration for DXCC purposes.
Disputes alone do not trigger deletion under those rules.

Conclusion:
The 1995 deletion rule is not triggered.

V. FINAL DETERMINATION

✅ BS7H — SCARBOROUGH REEF qualifies as an ARRL DXCC Entity under the 1995 DXCC Rules.

Qualification Basis (1995):

✔ Meets the 100-mile Geographic Separation Rule
✔ Recognized as a Chinese dependency for DXCC purposes
✔ Meets reef permanence criteria (above water at high tide)
✔ No political-entity criteria required
✔ No deletion criteria met

Conclusion:
Scarborough Reef was properly added as a Geographic Offshore Entity under the 1995 Rules, and its qualification is fully supported by the criteria then in effect.

VI. SUMMARY TABLE
