SV1AB and SV1IO on 1��296 MHz who could hear what was going on。 I 

remember SV1AB got very excited and began shouting `I can hear him�察�I 

can hear him��' The QSO was with VE7BQH。 Later Lionel sent me a very 

valuable   present�察  �valuable   not   for   its   cost   but   for   the   fact   that   it   was 

something   quite   unobtainable in   Greece   at   that time      a   very  low´noise

       ;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。 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。 The 

reason     may    have    been    a  very   simple    one�此  �the   polarisation     of  signals 

returning from the Moon varies from one moment to the other�察�so if you 

have     been    transmitting      with   horizontal     polarisation      and   go    over   to 

reception   it   is   very   easy   to   miss   the   answer   of   the   other   station   if   the 

polarisation has changed。; 

       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   calling   frequency   for   Moonbounce   is   144。011   MHz。�察  �and   the 

duration of the call is 2 minutes�察�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�察�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。 But if he has heard you he will alter the pattern。 

For   the   first   half   minute   he   will   send   SV1OE   DE   G3FNJ   and   for   the 

ensuing minute and a half he will transmit the letter O which signifies that 

he has heard your callsign completely and without difficulty i。e。 Q5 in the 

Q Code。 If I have also heard your callsign completely I will send G3FNJ 

for half a minute followed by RO for a minute and a half�察�which means 

that I have also received your callsign and your O。 And you will reply RO 

73 which concludes the successful contact。 

       ;There   are   one   or   two   other   letters   that   can   be   used。   Sending   M 

signifies that I hear you well but can only copy 50�ァ�of your transmission�察�

equivalent to Q3。 And the letter T signifies I hear you but cannot read you

                        CHAPTER EIGHT 



               PERSONAL REMINISCENCES AND ANECDOTES 

       The eight items which follow are not strictly part of the story of the 

development of amateur radio�察�but they deal with some historical events 

which   are   connected   with   our   hobby。  Two   are   of   particular   interest�此  �the 

account given to me by Takis Coumbias formerly SV1AAA of the early 

days of amateur radio in Russia and the story of the Greek broadcasts from 

Cairo�察  �Egypt   during   the   German/Italian   occupation   of   Greece   in   World 

War II。 

     Nearly all the photographs of the period were taken by the author。 

     1。 Athanasios 'Takis' Coumbias ��1909´1987�� 

       When I met Takis in his office in May 1983 I told him I was thinking 

of   writing   a   small   book   about   the   history   of   amateur   radio   in   Greece 

before it was too late  so many of the old timers had already passed away。 

Little did we both suspect at the time that he also would not live to see the 

finished project。 I asked him how far back he could remember。 

       ;Well�察  �I   can   start   from   1924   when   I   was   about   15   and   living   in 

Odessa in the Soviet Union。 There was a lot of interest in wireless and two 

magazines       were    published    in   Russia    which    dealt   mainly     with   the 

construction of receivers。 My interest was first aroused when a friend of 

mine at school proudly showed me something he had just made。 It was�察�he 

told me�察�a variable capacitor and he was going to use it to make a radio 

receiver。   The   contraption   was   enormous   by   today's   standards   and   must 

have weighed about half a kilo。 My friend said it had a capacity of   250 

micro´micro farads�察�which meant absolutely nothing to me at the time。 

       ;When     he   completed     his  receiver   I  became     very   interested   and 

decided I would build one too。 But materials were hard to find and very 

expensive。 Two items one had to buy�此�valves and headphones。 

       ;I asked my friend where he had found the sheet metal to make the 

plates of the capacitor。 He took me to a row of small shops which had a 

metal´faced ledge below the shop window。 The metal was thin and seemed 

easy   enough   to   remove。   We   sat   on   the   ledge   for   a   while   and   when   the 

coast was clear we tore away a section and ran like mad。 Later I ruined a

pair   of   my   mother's   dressmaking   scissors   cutting   out   the   plates。   I   used 

rings of some thick   copper wire to space the plates but   I could not  drill 

holes in the plates for the spindle so a friend did that for me。 I used about 

15 plates and to this day I have no idea what the capacity of the finished 

capacitor was。 Some small items for the receiver could be found in a little 

shop owned by an old man who charged exorbitant prices�察�so I decided I 

must go to Moscow for the valve and a single headphone that I needed。 

       ;But   Moscow   was   three   days   and   two   nights   away   by  train�察  �and   it 

was the middle of winter。 So what�察�you may ask。 Like many others I had to 

travel on the roof of a goods waggon。 I took with me a loaf of bread�察�a 

piece of cheese and two hard´boiled eggs。 My father said I must be mad 

but he gave me some spending money and his blessing。 

       ;I   had   eaten   my   food   by   the   end   of   the   second   day   so   when   we 

stopped at Brensk which is famous for its 'piroushki' I decided to try them。 

They were kept warm in large metal tins ready for the arrival of the train。 

There were seven varieties and I had one made with liver and a savoury 

sauce。 

       ;When I arrived in Moscow I went to see the Greek ambassador as I 

was     carrying    a  letter  of  introduction      from   my    father   who    was    acting 

Consul   for   Greece   in   Odessa�察  �but   it   was   Saturday   and   the   ambassador's 

office was closed。 I learned later that only foreign establishments closed at 

the   week´end。   So   I   went   to   look   for   a   cheap   hotel。   Looking   out   of   the 

bedroom window I saw a lot of people running in one direction。 At that 

moment a woman brought me a towel and a small bar of soap�察�so I asked 

her what was going on outside。 She said the butcher near the hotel had just 

received   some   liver。   Would   she   buy   me   some   I   said。   I   gave   her   some 

money and she returned nearly two hours later with the liver wrapped in 

newspaper。 When   I   opened   it   I saw  it   was horse liver   cooked   with   corn 

and   it   had   an   awful   sour   smell。   I   just   could   not   face   it�察  �although   I   was 

starving by now。; 

       I   asked   Takis   about   the   shops   in   Moscow。   He   said   he   had   found 

several shops with parts and some made´up receivers in the State owned 

shops。     He    learned    later  that   these   receivers     were    made    by   amateurs 

because      the  factories    only   made     equipment      for  the   armed     forces。   He

bought a triode valve called 'MICRO' and was told it had an amplification 

factor of 7。 He wrapped it carefully in cotton wool for the return journey 

to Odessa。 He also bought a dry battery pack which gave 80 volts�察�and an 

enormous single headphone for one ear which was ex´army surplus。 

       When he returned home and began to build his receiver he raided his 

mother's kitchen to build things like terminals�察�switches etc。 There was an 

electric bell circuit between the dining room and the kitchen and as they 

didn't use it his mother said he could dismantle it and use the wire�察�which 

was quite long because it went up into the loft and then down again to the 

kitchen。 

       ;I had acquired a small square of bakelite and I used a penknife to 

make a holder for the valve�察�twisting a few turns of wire round the pins as 

I could fin
