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. In 1970 Costas Tzezairlidis SV4CG built a unique electro mechanical machine using two motors to achieve horizontal and vertical scanning.
The first two licensed amateurs to make contact on 2 metres in Greece 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.
