Amateur Radio Licenses in EUDI Wallet - CEPT T/R 61-01, HAREC, ECC (05)06, PuB-EAA

Amateur radio licenses are issued as Public Electronic Attestations of Attributes (PuB-EAA) in EUDI Wallets by national telecommunications authorities, enabling smooth cross-border ham radio operation under CEPT T/R 61-01 reciprocal agreements without carrying physical documentation.

CEPT Framework: European Amateur Radio Reciprocal Licensing

Amateur radio international reciprocal operating agreements permit amateur radio operators from one country to operate a station whilst traveling in another without the need to obtain additional licenses or permits. This established framework provides the perfect foundation for EUDI Wallet digital credential implementation.

Three CEPT Recommendations for Amateur Radio

1. CEPT T/R 61-01 (1985): Full Reciprocal Operating Privileges

The 1985 initiative by CEPT, which resulted in CEPT ECC Recommendation T/R 61-01, has made it possible for radio amateurs from CEPT countries to operate during short visits in other CEPT countries without obtaining an individual temporary licence from the visited CEPT country.

CEPT Recommendation T/R 61-01 (CEPT Radio Amateur License) accords full reciprocal operating privileges to amateur operators holding equivalent license classes. Operators authorized under T/R 61-01 can transmit on all amateur radio frequency bands allocated to their license class in the visited country.

2. CEPT T/R 61-02 (1990): HAREC for Longer Stays

CEPT Recommendation T/R 61-02 was first approved in 1990, allowing CEPT administrations to issue a Harmonised Amateur Radio Examination Certificate (HAREC), which shows proof of successfully passing an amateur radio examination.

The HAREC facilitates the issuing of an individual licence to radio amateurs who stay in a country for a longer term than that mentioned in CEPT Recommendation T/R 61-01. The HAREC document demonstrates competency by showing proof of successfully passing an examination which complies with the Examination Syllabus for the HAREC.

3. ECC Recommendation (05)06 (2005): Novice License

Following the success of the CEPT Radio Amateur Licence detailed in CEPT Recommendation T/R 61-01, in 2005, a CEPT Novice Radio Amateur Licence was developed. The CEPT Novice Licence is detailed in ECC Recommendation (05)06 and has a lower standard than the CEPT Radio Amateur Licence.

The Novice license provides entry-level reciprocal operating privileges with restricted frequency bands and power levels, enabling new radio amateurs to gain international operating experience while developing skills before advancing to full license classes.

Public Electronic Attestations of Attributes (PuB-EAA)

Amateur radio licenses are issued as Public EAA (PuB-EAA), digital attestations issued on behalf of public sector bodies when data originates from official registries, particularly relevant for professional qualifications and government-issued licenses.

National telecommunications authorities (such as Ofcom, BNetzA, ANFR, Agcom) issue amateur radio licenses from official spectrum management databases as PuB-EAA in EUDI Wallets, providing cryptographically verifiable credentials that replace physical license certificates and HAREC documents.

Verified Attributes in Amateur Radio Credentials

Amateur radio licenses issued as PuB-EAA in EUDI Wallets contain verified attributes confirming regulatory compliance and operating authority:

Call sign: Unique station identifier assigned by national telecommunications authority following International Telecommunication Union (ITU) prefix allocation (e.g., DL for Germany, F for France, PA for Netherlands).

License class: Operator privilege level (Full/Extra, General, Novice) determining authorized frequency bands, power limits, and operating modes under CEPT T/R 61-01 or ECC (05)06.

Frequency authorizations: Specific amateur radio bands allocated to license class (HF, VHF, UHF, microwave), with transmit power limits (e.g., 100W, 400W, 1500W peak envelope power).

HAREC certification: Harmonised Amateur Radio Examination Certificate status confirming examination compliance for longer-term reciprocal operation under T/R 61-02.

CEPT reciprocal status: Confirmation that license qualifies for T/R 61-01 (full) or ECC (05)06 (novice) reciprocal operating privileges in CEPT member countries.

License validity period: Issue date, expiration date (typically 5-10 years), and renewal status ensuring current authorization before transmitting.

Cross-Border Operating Workflow with EUDI Wallet

Radio amateurs operating under CEPT reciprocal agreements present amateur radio licenses from EUDI Wallets instead of carrying physical documentation:

Step 1: Verify reciprocal status before travel: Amateur operator checks that destination country is CEPT member implementing T/R 61-01 or ECC (05)06, confirming reciprocal operating authorization.

Step 2: Construct visitor call sign: Operator determines proper call sign format for visited country (e.g., German DL2ABC operating in Netherlands uses PA/DL2ABC or DL2ABC/PA prefix/suffix).

Step 3: Present digital license if inspected: If telecommunications authority conducts spectrum monitoring or station inspection, operator presents amateur radio license from EUDI Wallet instead of physical license certificate.

Step 4: Authority verifies PuB-EAA: Telecommunications inspector uses relying party verification system to cryptographically confirm license authenticity, validating call sign, license class, CEPT reciprocal status, and expiration date.

Step 5: Operating authorization confirmed: Inspection validates that operator is authorized under CEPT T/R 61-01 or ECC (05)06, complying with visited country's frequency allocations, power limits, and operating regulations.

Important Limitations and Documentation Requirements

Not all European countries have implemented CEPT recommendations. Therefore, operators do not have reciprocal privileges in many countries, including popular travel destinations like Italy, the UK, or France (for certain license classes). Operators must verify specific country reciprocal agreements before traveling.

CEPT only authorizes in-person operation from within signatory countries. CEPT does not address remote operation from inside or outside a country. Operators must be physically present in the country when transmitting.

Operators must carry proper documentation: license (now via EUDI Wallet), proof of citizenship, and relevant public notices, and follow the host country's regulations when operating under CEPT agreements.

National Telecommunications Authorities as Issuers

National telecommunications regulators responsible for amateur radio licensing issue PuB-EAA credentials from official spectrum management databases:

Ofcom (United Kingdom): Issues amateur radio licenses with unique M, G, 2E call sign prefixes from radio licensing database.

BNetzA (Germany): Bundesnetzagentur issues licenses with DL, DA, DB, DC, DD, DE, DF, DG, DH, DI, DJ, DK, DL, DM, DN, DO call sign prefixes.

ANFR (France): Agence Nationale des Fréquences issues licenses with F call sign prefix from national frequency registry.

Agcom (Italy): Autorità per le Garanzie nelle Comunicazioni issues licenses with I call sign prefix, supporting CEPT reciprocal agreements.

Amateur Radio Associations and Credential Verification

National amateur radio societies (DARC, RSGB, REF, ARI) can verify EUDI Wallet credentials when members request IARU confirmation letters, contest certificates, or award program documentation requiring license class verification.

Emergency communications coordinators can verify operator credentials when activating emergency communication networks during disasters, confirming licensed amateurs before granting access to emergency frequencies.

Spectrum Monitoring and Enforcement

Telecommunications authorities conduct spectrum monitoring to detect unauthorized transmissions, interference, and regulatory violations. When inspectors identify suspicious amateur radio operation, they can request operators to present licenses from EUDI Wallets for immediate cryptographic verification.

Enforcement actions for unlicensed operation, excessive power, out-of-band transmission, or operation without proper reciprocal authorization can be streamlined through digital license verification, preventing disputes over physical documentation authenticity or expiration status.

Implementation Timeline Throughout 2028

Following the December 2026 EUDI Wallet rollout and December 2027 mandatory private sector acceptance, national telecommunications authorities implement amateur radio license issuance as PuB-EAA throughout 2028, using established CEPT framework and existing spectrum management databases.

With Public EAA (PuB-EAA) enabling national telecommunications authority issuance from official registries, CEPT T/R 61-01 (1985) providing full reciprocal operating privileges for short visits, T/R 61-02 (1990) facilitating HAREC certificates for longer stays, ECC (05)06 (2005) supporting Novice license reciprocal agreements, verified attributes confirming call signs, license classes, frequency authorizations, and CEPT reciprocal status, cross-border operating workflow replacing physical documentation with cryptographic verification, and national telecommunications authorities (Ofcom, BNetzA, ANFR, Agcom) issuing from spectrum management databases, amateur radio licenses demonstrate how EUDI Wallet credentials enhance regulatory compliance and international operating convenience for radio amateurs.

The combination of established CEPT reciprocal framework (four decades of cross-border operation since 1985), public sector registry integration (PuB-EAA from telecommunications authorities), complete attribute verification (call signs, frequency authorizations, power limits, HAREC certification), smooth cross-border operation (T/R 61-01 short visits, T/R 61-02 longer stays, ECC (05)06 Novice), and enforcement support (spectrum monitoring, inspection verification) positions amateur radio licenses as a model use case for government-issued credentials in the EUDI Wallet ecosystem — demonstrating how digital identity infrastructure modernizes regulatory compliance while preserving international reciprocal agreements that have enabled global amateur radio communication for decades.
