"In 1970 a technician from Stanford University came to Athens because the tracking station they had set up on Mount Pendeli could not pick the University's satellite, whereas they were getting good signals from it in Spain.One of the assistants at the station told the American that he knew an amateur who could pick up signals from satellites, meaning me.The American, who happened to be an amateur himself, immediately asked to see me.When he saw my 8 antenna array he suggested we should use it to try and pick up the University satellite.I pointed out to him that my array was for 144 MHz whereas the satellite beacon was transmitting on 136 MHz.He gave me the coordinates for the next pass and I rotatedand raised my array in anticipation.When the exact time arrived my modest receiver picked up the satellite beacon loud and clear.The American got so excited he asked me if he could use my telephone to call the University in the U.S.A.He told them the satellite had been heard at last in Athens, and by an amateur no less.Later I received a letter from NASA thanking me for the assistance I had given.When the American left he gave me that 50 MHz converter you can see there on the shelf."Norman: "Tell me about your contribution to the transequatorial tests of 1979."SV1AB: "I had been in regular contact with ZS6LN on ten metres long before Costas SV1DH appeared on the scene.I remember asking ZS6LN why we should not receive South African stations on 2 metres when we could hear them so well on 50 MHz.He had replied that the two frequencies behaved in a very different manner, but there was no harm in trying.He got ZS6PW and ZS6DN interested in the idea, particularly ZS6DN who had much better aerials and a very good QTH.He was the one who stood the better chance of being heard in Greece.We arranged a schedule of transmitting and listening every evening.First they transmitted and we listened, and then we transmitted and they listened, and contact was maintained on ten metres."Norman: "You said `every evening' --do you mean that the Sun has something to do with this type of propagation?"George: "Most certainly.All the contacts that were made subsequently were at least one hour after the relevant part of the ionosphere was in darkness."George then described how the first signals were heard via transequatorial propagation.
George: "First we heard the beacon on 144.160 MHz set up by Ray Cracknell ZE2JV in Southern Rhodesia (now Zimbabwe).The date was April 12th 1978 at 18.00 G.M.T.Ten months later I heard ZS6DN's automatic beacon with a colossal signal, but he was not at home! I went to 20 metres and put out a frantic CQ for any station in South Africa but got no reply.I returned to the cross-band frequency on 10 metres which we used regularly for 28/50 MHz QSOs and managed to contact a station inSouth Africa who was very far away from ZS6DN but who kindly offered to QSP a message by telephone.He was told that ZS6DN had gone out but would be back soon.I was terrified that the opening would not last long enough.But in a few minutes I heard him calling me slowly on CW and we exchanged reports at 17.20 G.M.T on February 16th 1979.This was a new world record for the longest distance on 2 metres"Three days earlier, however, when I was not at home, Costas SV1DH had established the first TEP contact between Greece and South Africa when he contacted ZS6DN.As you know, my location is a mere 10 kilometres north of SV1DH's.I have a tape recording of my QSO with ZS6DN as well as with ZS6PW whose signals came through a few minutes later at 17.34 G.M.T.on that historic evening.(The local time in Athens was 7.34 p.m.).Of course the distance record was broken again on September 17th 1981 when I contacted ZS4BU who is 110 kilometres further south than ZS6DN."Norman: "Were all these contacts only on the key?"George: "Yes, all the contacts were on CW.On several occasions we tried SSB but there was so much distortion that not a single word could be identified.TEP has a lot of flutter and fading and as you can hear on the tapes even the morse comes through like a breathing noise, not a clear tone.This applies to contacts between Greece and South Africa.Contacts between Japan and Australia where the distances involved are smaller, have been made on SSB."Norman: "What about cycle 22?"
George: "see how things go.If anything is achieved it should be in 1990 or later.With modern equipment we shall be able to hear signals that were buried in the noise in 1979."4.Dr Spyros Tsaltas SV1AT & George Delikaris SV1AM.(Mobile).The first two licensed amateurs to make contact on 2 metres inGreece were Dr Spyros Tsaltas SV1AT and George Delikaris SV1AM.They had put together the famous Heathkit `TWOER'.Crystals were plentiful on the surplus market, but it was not easy to find two of the same frequency.SV1AT transmitted on 144.720 and SV1AM on 145.135 MHz.The first contact took place at 13.30 local time on the 21st of December1963.
A few days later SV1AT had a cross-band QSO with George Vernardakis SV1AB who was transmitting in the 20 metre band on 14.250 MHz A.M.as he had not completed his TWOER yet.
At that time SV1AT was the Secretary of the Radio Amateur Association of Greece.He suggested to the Committee that the Club should apply for a temporary licence to be granted to SV1AM enabling him to transmit from his vehicle while in motion.The licensing authority gave the licence "for experimental purposes only, and for a period not exceeding one month".
And so it was that the first `mobile' QSO took place on 2 metres between licensed Greek amateurs on the 27th of January 1965 at 19.25 local time.SV1AM was travelling in his car and SV1AT was at his home QTH.
