The IARU (International Amateur Radio Union) was founded on April 18, 1925. Every year, this event is honored worldwide with the World Amateur Radio Day. The USKA and the Swiss radio amateurs do this by activating the association call sign HB9WARD, this year specifically with HB100IARU throughout the month of April. The operation is carried out by interested operators – individuals or groups and clubs – from their respective locations. If even outsiders can be informed and motivated to use amateur radio during the activations, all the better.
When: 01 April 2025 – 30 April 2025
Bands: All bands are authorised according to the licence, including WARC. Special stations may operate on WARC, only contest operation is not permitted.
Operating modes: Phone, CW, Digital.
Other approved amateur radio bands and operating modes are also possible if interested and after consultation. Attention: No special activities are permitted on the WARC bands (30m, 17m, 12m).
Maximum power: in accordance with Swiss legislation.
