ARRL DXCC ENTITY RE-EVALUATION MEMORANDUM – 3D2/C

3D2/C — CONWAY REEF
Evaluation Under 1990 ARRL DXCC Rules

I. PURPOSE

This memorandum evaluates whether 3D2/C — Conway Reef qualifies as a separate ARRL DXCC Entity under the 1990 ARRL DXCC Rules.

The evaluation includes:

• Political-entity criteria
• Geographic island-separation criteria
• Reef/shelf discontinuity
• Remote-uninhabited-island provisions
• 1990 deletion and validity checks

Conway Reef appears on the DXCC List as a geographic island entity, distinct from mainland Fiji (3D2).

II. BACKGROUND

Political & Administrative Status

• Conway Reef (Ceva-i-Ra Reef) is a Fijian territory.
• Located ~450 km southwest of Viti Levu, Fiji’s main island.
• No resident population; used periodically for navigation, maritime, or DXpedition purposes.
• Governance: under the Fiji Ministry responsible for offshore islands and reefs.

Geographic Characteristics

• A very small coral platform ~2 m above high tide at its highest point.
• Dimensions vary by tide and storm action.
• One of Fiji’s remotest possessions — far outside any coastal platform or shelf.
• Sits on its own isolated submarine mount.

DXCC Prefix

• DXCC assigns 3D2/C for Conway Reef.
• Distinct from:
– 3D2/R Rotuma
– 3D2 Fiji main islands

DXCC History

• Recognized as a distinct DXCC Entity under the evolved geographic-island rules established 1978–1990.
• Treated similarly to other isolated offshore reefs with no shelf connection (e.g., Scarborough Reef, Minami Torishima, Mellish Reef).

III. ANALYSIS UNDER THE 1990 DXCC RULES

The 1990 Rules split entity qualification into:

Political Entities
Geographic Entities
- Offshore Island Rule
- “Second Island Entity” Rule
- Reef/Shelf separation requirement
- Minimum separation distance (≥350 km)

Conway Reef qualifies exclusively under Geographic Entity criteria.

1. POLITICAL ENTITY CRITERIA (1990)

1(a) Sovereign state — FAIL

• Conway Reef is not sovereign; incorporated into Fiji.

1(b) Administrative separation — FAIL

• No local government or province-level autonomy.

1(c) ITU prefix block — PASS (but insufficient)

• Fiji (3D2) has a valid ITU prefix block, but this does not qualify Conway Reef as a political entity.

Conclusion:
Conway Reef cannot qualify as a political DXCC Entity.

2. GEOGRAPHIC ENTITY CRITERIA (1990)

This is the qualifying path for 3D2/C.

2(a) Permanently above high tide — ✔ PASS

• Conway Reef has a natural sand and coral cay above high tide, although barely.
• ARRL 1990 policy accepts low sand cays like:
– Scarborough Reef (BS7)
– Mellish Reef (VK9M)
– Minami Torishima (JD/M)

2(b) ≥350 km separation from parent entity — ✔ PASS

Fiji’s main landmass (Viti Levu) ≈ 450 km from Conway Reef.

Exceeds the 350 km requirement.

2(c) No land/shelf connection — ✔ PASS

• No land, reef, or continuous shallow platform links Conway Reef to Fiji.
• The reef sits on its own submarine bank.
• Depths between Fiji and Conway Reef drop thousands of meters.

2(d) Distinct geographic island group — ✔ PASS

• Conway Reef is a single-reef island group.
• Meets DXCC criteria for “geographically distinct features not contiguous with the parent.”

2(e) Supports amateur radio operation — ✔ PASS

• Multiple successful DXpeditions.
• Sufficient landmass above high tide for antenna systems.

2(f) Not man-made; natural feature — ✔ PASS

• Entirely natural coral formation.

Conclusion:
Conway Reef fully satisfies all 1990 offshore-island requirements.

3. SPECIAL-AREA CRITERIA (1990)

• Not Antarctic
• Not an international headquarters
• No special-status territory

Not applicable.

4. 1990 DELETION CRITERIA — NOT TRIGGERED

Deletion occurs if:

The island is no longer above high tide
The entity was added in error
A political integration or geographic change eliminates the separation

In 1990:

• Conway Reef remained fully above high tide (barely, but valid).
• Separation remains >350 km.
• Reef still isolated on a separate seamount.
• It was deliberately added by ARRL using the offshore-island rule.

No deletion criteria were met in 1990.

V. FINAL DETERMINATION

✅ 3D2/C — Conway Reef qualifies as an ARRL DXCC Entity under the 1990 DXCC Rules.

Qualification Basis (1990):

✔ Offshore-island geographic separation
✔ >350 km from Fiji (main islands)
✔ Fully natural and above high tide
✔ No land, reef, platform, or shelf connection
✔ Consistent with ARRL treatment of isolated reef entities
✔ Demonstrably supportable for amateur operation

Conclusion:
Under the 1990 DXCC Rules, Conway Reef is a valid and properly recognized Geographic DXCC Entity, qualifying via offshore-island separation.
