Possible end of an ERA transmitting via shortwaves.
According to this article (in Greek):
The ERT CEO Giorgos Gambritsos has signed a decree to close down the shortwave transmitting facility at Avlida, Greece after March 31, 2022. The news release by ERT is leaving the possibility of shortwave broadcasts to continue only if the Ministry of Defense and Foreign Ministry decide to oversee the continuation of broadcasts on shortwave.
The article also mentions that only three MW broadcast centers will continue to broadcast and will be maintained (Bogiati 729 kHz, Kerkyra 1008 kHz and Tripoli 1314 kHz).
