The former beacon (HELA) stopped transmitting on April 8. 2. A new beacon (model 2.0) has been installed, which started transmitting on April 9. 3. The Starec antenna (type B) is centered above a mark on a concrete block, located about 10 m from the old antenna. The DOMES number for the new antenna reference point is 30606S003. The acronym in the data files for this new station is : HELB. The main reason why this station has been upgraded is that the former antenna is about to fall down because its support is highly corroded.
