(Without extra /HE) to make understandable the working station her QTH. Some foreign, amateur radio operators living away from that time had no idea of the existence of the Principality of Liechtenstein - for graduate may have a separate DXCC country a counting. It took a long time, especially on CW, repeatedly having to explain the location. All radio activities during further two years in Liechtenstein were made in the course of the series with the callsign HB1../HE for every DXer. This situation was not unknown in Bern.

This in turn led immediately to the appeal of the anchor radio groups now grown to 12 members in Liechtenstein under conductor device by Gunther Erich Holzknecht HB0CZS. At the same time was taken in Vaduz is now responsible for postal service and telecommunications in operation.
