From Tony N2MFT:
Helgoland hop
Over twenty amateur radio operators will activate the German island
of Helgoland for two weeks, starting this Friday, the 25th of March.
The group will be using two callsigns. DA0HEL will be used on the
main island, located in the German Bight. The second callsign DL0IH
will be used during daytime from the uninhabited dune island next to
Helgoland, limited by the tides and the ferry timetables.
The youth hostel on the island will provide accomodation and serve
as the shack for operations on all bands, on all modes. Contacts
with the team on Helgoland will count towards the RSGB-IOTA diploma,
Helgoland and the neighbouring dune share the IOTA number EU-127
