Greek amateur to have two…way contacts using radio telephony； way back
in 1921。 He was also the first amateur to operate from the island of Crete
in 1938。
2。 Dr Costas Fimerelis SV1DH。 （Transequatorial propagation）。
On October 9th 1988 at 23。10 GMT a new world distance record was
established on the 50 MHz band by the Greek experimental station
SZ2DH operated by Costas Fimerelis SV1DH and a station in Tokyo；
when it was proved that the signals had travelled a distance of 30；650 over
the South American continent。 This is 15；000 kilometres more than the
short path between the two stations； over which there was absolutely no
propagation at that moment in time。
A simple 5 element Yagi and a power of 100 watts was used at
SZ2DH。 The contact was on CW but the signals were so strong that it
might well have been on SSB。 It is estimated that 8 hops were needed to
cover this record distance。
Most people know by now that SV1DH was one of the principal
stations involved in the very successful Transequatorial propagation tests
which took place during the 21st sunspot cycle between 1977 and 1983。
Costas gave me a simplified explanation of the phenomenon first noticed
by Ray Cracknell ZE2JV and Roland Whiting 5B4WR way back in
September 1957； namely that VHF signals can travel great distances
across the equator （5；000 to 8；000 kilometres） during the years of high
sunspot activity。
Costas said that usually stations located approximately the same
distance north and south of the magnetic （not geographic） equator can
contact each other shortly after sunset at both locations。 The first such
QSO took place on the 10th April 1978 between ZE2JV and 5B4WR。 Two
days later ZE2JV contacted George Vernardakis SV1AB and this contact
was followed a few days later with QSOs with SV1DH and SV1CS。

The dawn of amateur radio in the U。K。 and Greece ： a personal view
（Fuller details of these contacts are given later in this book in the interview
with SV1AB）。
In October 1976 there was a rumour that 145 MHz signals had been
heard directly between Argentina and Venezuela。 With the imminent
beginning of sunspot cycle 21 many amateurs in the northern and southern
hemispheres began organizing tests on 50；144；220 and 432 MHz。 Within
less than a year successful 2…way contact was established between
Argentina and Venezuela on 144 MHz。
Greece is favourably placed for TEP to countries in Africa where
there is considerable amateur radio activity； like Zimbabwe and the Union
of South Africa。 So towards the end of 1977 SV1AB and SV1DH began
looking for colleagues in suitable geographic locations with the
appropriate equipment and the time and inclination to engage in tests
which could go on for months and months on end。 Very soon the following
stations agreed to participate in the tests。 The northern group included
SV1AB； SV1DH； 5B4WR and 5B4AZ。 In the southern hemisphere
participants were ZE2JV （now G2AHU）； ZS6PW； ZS6DN； ZS6LN and
ZS3B。
After 4 months of daily test schedules； early in 1978； successful
contacts took place on 144 MHz； some of which constituted world
distance records for that time； as can be seen in the accompanying table。
Amateurs in Malta； Italy； France and Spain soon began to participate in the
tests； as well as amateurs in other areas of South Africa。
It can be seen from the world map that the magnetic dip （shown as a
heavy line） is very different to the geographic equator。 The QTH of
SV1AB is in a suburb 10 kilometres north of SV1DH's so George's
contacts with the stations in Africa always had that edge on them。
In South Africa Dave Larson ZS6DN had set up a beacon which was
first heard in Athens by SV1AB in February 1979。 Within a few days
ZS6DN had QSOs with SV1DH and SV1AB。 The latter contact was a
world distance record via the F…regions of the ionosphere because of the
extra distance involved owing to the locations of the two Greek stations；
as mentioned in the previous paragraph。

3。 George Vernardakis SV1AB。 （V。H。F。）
In March 1988 I visited George Vernardakis SV1AB （formerly F9QN
of Marseilles； France） who spoke to me about his contribution to the
transequatorial tests and his other experiments in connection with
Moonbounce； Meteor Scatter and Sporadic E propagation。
〃In 1965〃 George told me； 〃I was the only SV station equipped for
