"After the successful launch of Oscar 10 those amateurs who had complex antenna systems and low-noise receivers they had used for Moonbounce congregated on 145.950 and spoke to each other on QRP which prevented ordinary mortals from hearing them. By QRP I mean outputs of half a watt or less.

The calling frequency for Moonbounce is 144.011 MHz., and the duration of the call is 2 minutes, but for the first minute and a half you call CQ DE SV1OE and during the last half minute you also give the call of the station you are trying to contact, for instance G3FNJ DE SV1OE. You must on no account transmit for more than two minutes because at the beginning of the third minute the other station will begin transmitting the same pattern of signals.

I was hoping to make some Moonbounce contacts, but at that time it was very difficult to construct low noise preamplifiers. After many days and hours of trying I managed a single brief contact with F8DO in France. Some time later I heard that Mike Staal K6MYC had heard me in California.

SV1OE then explained the very strict procedure which must be adhered to for Moonbounce schedules. "Schedules are arranged to last one hour. The first station to start transmitting on the hour must be the one whose QTH lies to the east of the other.

"The funny thing about this aerial array was that it enabled me to receive television signals from Nigeria on Channel 3 but only when I raised it up to an elevation of nearly 90 degrees." Norman: "I understand that Costas Georgiou SV1OE is the only Greek amateur who has had successful QSOs via Moonbounce." George: "Yes indeed. But it was many years later, using a low noise GASFET preamplifier.

But when finally one day I broke into a net QSO I arranged schedules for Moonbounce with two stations in Sweden. I had a successful contact with one of them but never heard the other.

In 1982 Costas had been trying for three years, without success, to hear his own signal via Moonbounce. The reason for his failure was that he was unaware of a very basic fact. "I was completely ignorant of the Doppler shift effect," Costas told me. "The frequency of received signals varies according to the position of the moon.

Up to the end of 1988 the only Greek amateur who had positively authenticated Moonbounce contacts was Costas Georgiou SV1OE. His very first contact was made in 1982 when he contacted VE7BQH in Canada on 2 metres. In the ensuing four years Costas managed to work four more stations: K1WHS, SM4GVF, W5UN and KB8RQ.
