ei1MG – G. Manni, Rome: "Usque ad aras", with a Photograph of the Station
Introduction
The second card from G. Manni's station in Via Principe Umberto 205, Rome (see also EI1MG-1927-01), is a folding card of unusual design: on the left a drawing of the Capitoline wolf on a pedestal inscribed "VSQVE AD ARAS – ei1MG", on the right a photograph of the station room with its wall of QSL cards and a horn loudspeaker. Il Radio Giornale printed the same photograph in November 1928 (page 34), captioned "ei 1MG", in its survey of Italian amateur activity. The card confirms a contact with nu2GP, Donald C. Sayer of Richmond Hill, New York, on 9 April 1928 at 05:00, with "RC sigs R6" (rectified AC note), and adds "Pos QSL ur card – I did!"; the back carries "Via A.R.I.", "Sure vy gld for QSO, hope cuagn" and the Hartford forwarding stamp.
The station in 1928
The magazine's monthly lists show ei1MG heard across Europe and beyond in the first half of 1928: in Spain in February (in telephony, with poor modulation), at Reims, in Syria, in Egypt, in Barcelona, Uppsala, Berlin, Barmen and Königsberg between January and March, in Estonia and in Sweden in May and June, and in Madrid and Barcelona in August. Manni published no activity reports of his own and did not enter the A.R.I. contests; his first name and profession are not recorded.
Between the two cards the transmitter grew from 75 to 100 watts, still a Hartley, while the receiver remained the "Heart" with detector and two audio stages covering 15–2,000 m. Of the two Rome QSL services of the period, this card went through the A.R.I. bureau rather than that of the magazine Radiofonia used for the 1927 card.
