Notice from Shanghai Coast Radio Station (XSG) on Hosting the Global Amateur Radio Communication Event
Dear Amateur Radio Enthusiasts,

The event will take place from 12 to 13 February 2025, using the station’s long-standing callsign, XSG.
Established in 1905, Shanghai Coast Radio Station celebrates its 120th anniversary this year.

QSL Confirmation:
Due to differing regulations set by amateur radio licensing authorities across the globe, XSG will only confirm amateur radio QSOs and SWL reports via paper QSL cards delivered by mail. If you wish to receive an XSG QSL card, please send your card to: No. 1 Diantai Road, Zhangjiang Town, Pudong New Area, Shanghai 201206, PR China. Email: hadt@shhadt.com.
Important Reminder:
To be clear, contacts with XSG will be cross-band contacts where XSG will operate on its authorized frequencies outside of the amateur radio bands, and any amateur radio operator making contact will operate within their own allocated amateur frequencies as listed above. Operators should exercise caution when operating split cross-band, ensuring they do not accidentally transmit on top of another station within the amateur bands. It’s a good practice to regularly monitor your transmit frequency.
Please note that amateur radio operators are not permitted to transmit on XSG’s dedicated frequencies. Operators must adhere to the transmission requirements in their respective licenses. It is recommended that amateur radio enthusiasts consult their national licensing authorities regarding applicable regulations before engaging in communications with XSG.
We warmly invite amateur radio operators worldwide to participate in this event and look forward to celebrating this milestone together.
