The club station operates under the 9H1MRC callsign, which uses Malta’s national 9H prefix assigned to all Maltese amateur‑radio stations. This callsign identifies the station as part of the Malta Amateur Radio Circle and is used for all club activities, including contests, special events, training sessions, and demonstrations. Operating under a recognized national prefix also ensures full compliance with Maltese licensing regulations and makes the station instantly recognizable to operators around the world during QSOs and international contests.
