The I1AA Radio Station: Società Ferrarese Amici delle Radiocomunicazioni' Pioneering Role in Early Italian Amateur Radio

Introduction

The Società Ferrarese Amici delle Radiocomunicazioni, established in 1923 in Ferrara, Italy, holds a distinguished place in the history of Italian amateur radio as the operator of station I1AA (initially 1AA in early notations). This society, a collective of radio enthusiasts and experimenters, began transmissions in December 1924 from the north-west tower of the iconic Castello Estense, marking it as the first officially recognized Italian amateur radio station. Chronicled in Il Radio Giornale and later historical accounts, I1AA symbolized the dawn of organized amateur radio in Italy, fostering technical innovation and community collaboration. As a section of the Radio Club Nazionale Italiano (R.C.N.I.), the society contributed to the amateur movement's growth, eventually merging into the Associazione Radiotecnica Italiana (A.R.I.) in 1927. Their efforts highlighted Ferrara as a "cradle" of Italian radiantismo (amateur radio), with activities emphasizing reception, emission tests, and education amid the 1920s' radiotelegraphy boom.

Technical Achievements and Experiments

The Società Ferrarese focused on practical experimentation, constructing and operating valve-based equipment for telegraphy and early telephony. Their station I1AA utilized modest setups, including unifilar antennas and receivers like the Bourne model with amplification stages, as detailed in reception logs.

Key highlights from Il Radio Giornale and historical sources:

• Radio Giornale, April 1924: The society is prominently mentioned under "Dalle Società," indicating active involvement in radio communications, likely including early transmission tests from Castello Estense.
• Radio Giornale, May 1925: A reception report lists their equipment: "Società Ferrarese - Amici delle Radiocomunicazioni - Ferrara. Ricev. Bourne, 1 A.F. 1 B.F. — Aereo unifil. 25 m." This setup (Bourne receiver with one audio frequency and one bass frequency stage, plus a 25-meter unifilar antenna) was used to intercept Italian stations such as i3AM, i1RT, i1AF, i1WB, and i3 in April 1925, demonstrating reliable medium-wave reception capabilities.
• Broader Activities: As per historical records, I1AA conducted initial transmissions in December 1924, focusing on shortwave and medium-wave experiments. The society's statute, notarized in 1923, emphasized building apparatus, aligning with R.C.N.I.'s promotion of circuits like neutrodina and tropadina in contemporary issues. QSL cards from I1AA confirm their emission activities, with addresses at Via del Gorgadello 19 (now a historical site in Ferrara).

These experiments underscored the society's role in advancing amateur construction and testing, often in group settings similar to workshops.

International Receptions and Recognition

While primarily focused on national activities, I1AA's signals and receptions extended to European and transatlantic logs, reflecting the era's propagation studies. As the first Italian amateur station, it garnered recognition for pioneering efforts.

• Interceptions and Logs: In January 1925, as noted in Il Radio Giornale (1925_03.pdf), the society compiled chronological lists of intercepted callsigns, contributing to community data on signal propagation. Their April 1925 log included multiple Italian stations, indicating strong local and regional reception.
• Historical Recognition: The station's inaugural transmissions in 1924 were hailed as a milestone, with QSL exchanges confirming contacts. By the centenary in 2023, I1AA was celebrated as the genesis of Italian amateur radio, with commemorations noting its role in early DX and emissions.
• Broader Impact: Though not as DX-focused as stations like 1GW, I1AA's activities paralleled international tests in "Le vie dello spazio" sections, inspiring logs from Europe and beyond.

Organizational Role and Legacy

As an early radio society, Società Ferrarese served as the Ferrara section of R.C.N.I., promoting amateur interests through statutes, meetings, and collaborations. Their merger into A.R.I. in 1927 integrated their expertise into the national framework.

• R.C.N.I. Affiliation: Mentioned in Il Radio Giornale as a society contributing reports and interceptions, they embodied group dynamics, similar to Associazione Radio Montatori.
• Legacy: Ferrara's amateur radio heritage, rooted in I1AA, is preserved by ARI Ferrara, with the 2023 centenary highlighting its foundational status. The society's emphasis on "amici" (friends) fostered community, influencing modern Italian ham radio sections and commemorations, as seen in historical accounts by figures like Franco Moretti I4FP. I1AA remains a symbol of Italy's radiantismo origins, bridging early experiments to organized amateur radio.
