ARRL DXCC ENTITY RE-EVALUATION MEMORANDUM – IS0

IS0 — SARDINIA
Evaluation Under 1947 ARRL DXCC Rules

I. PURPOSE

This memorandum evaluates whether IS0 — Sardinia would have qualified as a separate ARRL DXCC Entity under the 1947 ARRL DXCC Rules, the governing criteria when the post–World War II DXCC List was reconstituted.

The evaluation includes:

• Political status and sovereignty
• Administrative relationship to Italy
• Geographic distinctiveness
• Telecommunications and prefix allocation
• Applicability of the 1947 political and geographic DXCC criteria
• Final determination

II. BACKGROUND

A. Political & Administrative Status (1947)

In 1947, Sardinia was:

• A region of the sovereign state Italy
• Fully administered as part of the Italian Republic
• Lacking any independent:
– Sovereignty
– Governmental authority
– International diplomatic recognition
• Not a colony, protectorate, trust territory, or mandated territory
• Not a special extraterritorial possession

Thus, Sardinia was entirely integrated within the state of Italy, without any DXCC-relevant political independence.

B. International Standing (1947)

As part of Italy:

• Sardinia did not possess separate diplomatic identity
• It did not appear on any list of international political entities
• No treaty organization or foreign government recognized Sardinia separately

Therefore, Sardinia fails the 1947 DXCC political-entity standard.

C. Telecommunications & Prefix Status (1947)

In 1947:

• Italy used the I prefix block nationally
• Sardinia did not have separate ITU-recognized prefixes
• The IS0 prefix was not yet assigned
• All amateur radio activity from Sardinia in 1947 used Italian callsigns

Lack of prefix independence eliminates one of the 1947 DXCC political indicators.

D. Geographic Characteristics

Sardinia is:

• A large island in the western Mediterranean
• Approximately 200 km west of mainland Italy
• Geologically part of the European continental margin

Under the 1947 rules:

Geographic separation alone was NOT a basis for separate DXCC Entity status.
Only remote overseas possessions or non-contiguous colonies qualified geographically.

Sardinia was neither.

E. DXCC Policy Context in 1947

The 1947 ARRL DXCC Rules recognized only:

1. Political Entities

• Independent sovereign nations
• Colonies
• Protectorates
• Mandates
• UN trust territories
• Overseas possessions

2. Geographic Entities

• Only remote island groups not politically part of their parent nation
• Examples: CE0 islands, EA8 Canary Islands, CT3 Madeira

Sardinia met none of these categories.

III. ANALYSIS UNDER 1947 DXCC RULES

1. POLITICAL ENTITY CRITERIA (1947) — FAIL

1(a) Sovereign Nation — ❌ FAIL

Sardinia was part of Italy; not sovereign.

1(b) Separate Government — ❌ FAIL

No autonomous political authority in 1947.

1(c) International Recognition — ❌ FAIL

No separate diplomatic identity.

1(d) Distinct Prefix — ❌ FAIL

No IS0 prefix in 1947.

Conclusion:
Sardinia fails all political-entity criteria.

2. GEOGRAPHIC ENTITY CRITERIA (1947) — FAIL

Geographic entities required:

• Political separation, or
• Remote overseas-possession status, or
• Administration separate from the parent government

Sardinia satisfied none.

Specifically:

2(a) Separated by Water — ✔ TRUE but not sufficient

Geography alone was not grounds for DXCC status in 1947.

2(b) Non-Contiguous Colonial or Overseas Possession — ❌ FAIL

Sardinia was not a colony.

2(c) Special Administrative Status — ❌ FAIL

No distinct governance in 1947.

Conclusion:
Sardinia does not meet the 1947 geographic entity requirements.

3. SPECIAL-AREA CRITERIA (1947) — NOT APPLICABLE

Sardinia was not a:

• Mandated territory
• UN trust territory
• Joint international zone

4. 1947 ADDITION / DELETION RULES

Addition (1947) requires:

✔ Sovereign state
—or—
✔ Colony/protectorate
—or—
✔ Overseas possession
—or—
✔ Remote non-contiguous geographic entity

Sardinia is none of these.

Deletion (1947) applies only if:

• A listed entity loses sovereignty or is absorbed
—Not relevant.

V. FINAL DETERMINATION

❌ IS0 — SARDINIA does NOT qualify as an ARRL DXCC Entity under the 1947 DXCC Rules.

Reasons:

✘ No sovereignty
✘ No separate administration
✘ Not a colony or protectorate
✘ Not an overseas possession
✘ Geographic separation was insufficient under 1947 rules

Conclusion:
Under the rules in force in 1947, Sardinia could not have appeared as a separate DXCC Entity.

It only qualifies later, under 1950–1955 reforms, which introduced the “separate political subdivision / separate call-area” criteria.
