Thessaloniki public radio fares medium-wave well and forever, as the historical transmitter of Perea, relaying the 102FM service of ERT3 on 1044 Khz, switched off for good. The medium-wave broadcast of 9.58FM at Malgara was switched off a bit earlier, on the 22nd of February.
The aforetime powerful transmitter of Perea is currently being dismantled and disassembled and its pieces are going to be used as replacement parts for transmitters of the same type which will keep broadcasting. Meanwhile, the rest of the equipment is to be removed from the estate, which is being cleared and according to newspaper reports [GRreporter] is one of the cherished pieces of land that are about to be given to the Fund for the State Property Development in order to be sold. It covers an area of 328 hectars between the airport and Perea which has been hosting the supporting buildings, two towers supporting the 99,5m-high medium-wave aerial and a forest of shorter shortwave antennas.
Switching off the two transmitters signals the end of an era for the Radio Station of Macedonia (ERT3), having made its first steps on the medium-wave and stayed there for 65 years. The first transmission on 1044 KHz took place on the 1st of March 1947 by EIR, whereas a transmitter was installed in Perea in 1954, initially having a power of 5KW. Today's settlement was given to the public radio by the Voice of America in 1972, including a transmitter of 50KW; in its peak it 25 employees of all specializations worked here.
The latest trasmitter of Peraia, a product of Siemens, had a maximum power of 200KW and got installed in 1984. It consisted of two trasmitters of 100KW each, operated with Pulse Digital Modulation (PDM) and featured a hybrid cooling system with blowing air and water. During the good times, its coverage used to spread over Greece, Balkans and Black Sea. Due to lack of replacement parts during the last years it operated with only 75KW, whereas since summer 2011 a severe modulation problem resulted to a very bad sound quality.
The transmitter of 1179 KHz at Malgara had been installed during 1973 by YENED, featured a power of 50KW and an aerial tower of 86m, which is still being used by ERA Sport (792 KHz).
Lots of devoted listeners are going to miss the “medium-wave of Thessaloniki”, as many residents of remote areas used to tune in the Radio Station of Macedonia, within or across the Greek borders, in order to get updated on the news of Northern Greece and keep in contact with the Diaspora Greeks who tuned in the shortwave service overnight.
