I1AS – 1926 Italian Amateur Radio Station

Introduction

The amateur radio station I1AS was operated by Dr. Silvio Pozzi, one of the early Italian pioneers of radio experimentation. Active from the mid-1920s, I1AS represents the spirit of individual scientific curiosity that characterized the formative years of Italian amateur radio. Pozzi was already recognized nationally by the early 1930s and is listed among Italian radiants in authoritative contemporary publications, confirming the technical and cultural relevance of his station.

Technical Achievements and Experiments

I1AS was born from a strong experimental vocation. Silvio Pozzi was known as an eclectic experimenter, initially fascinated by Hertzian waves and by the reproduction and construction of scientific instruments capable of generating sparks and radio-frequency energy.
His activity fits squarely within the transition from spark-based systems to more refined valve-based amateur transmitters. Although specific circuit diagrams are not preserved, his work reflects the typical advanced home-construction practices of the 1920s, emphasizing hands-on experimentation, measurement, and progressive refinement of equipment.

International Receptions and Recognition

The call sign I1AS appears in multiple key reference works:

• “Come funziona e si costruisce una Radio” by Ernesto Montù (1932)
• RADIO Schemi Call Book, 1st edition (1947)

This continuity of references over decades demonstrates that I1AS was not an obscure or short-lived station, but one well known within the Italian and international amateur radio community. After World War II, Silvio Pozzi was affectionately known on the air and within ARI circles as “Papà IRA”, a sign of deep respect and recognition by fellow operators.

Organizational Role and Legacy

Beyond his technical activity, Silvio Pozzi played a significant institutional role:

• National Councillor of ARI (Associazione Radioamatori Italiani) in 1948–1949
• Continued contributor and advisor to ARI even after his formal mandate

He was part of the group of pre-war amateurs who actively helped rebuild and revitalize Italian amateur radio after World War II, supporting Ernesto Montù (I1RG) during the critical post-war reconstitution of ARI.
Pozzi was known for his balanced attitude on the air: precise technical answers when asked, encouragement toward newcomers, and a consistently respectful operating style. His legacy extended through mentorship and example rather than self-promotion.
