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, 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, he told me, 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, 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: 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, 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, and it

was the middle of winter. So what, 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, 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, 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, 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, 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, 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, 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, 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, twisting a few turns of wire round the

pins as I could find nothing to use as a socket. I had no idea how to

connect the various items I made or bought. I had seen a circuit

diagram in a French magazine of a detector with reaction. I made the

connections by twisting wires together and finally the receiver was

complete. The next thing was the aerial. I made an enormous aerial

with four parallel wires, like the aerials I had seen on ships.

Putting it up was a dangerous operation as our house had a rather

steep tiled roof, so I got some friends to help me. Some of them who

had 'superior knowledge' told me the down-lead must have no bends. I

got hold of a stiff copper wire and supported the down-lead on two

enormous bell insulators as used on telegraph poles. I had to smash a

corner of my bedroom window to bring the wire in. I had bought a

large knife switch which could be turned over to connect the aerial to

ground. I was afraid the large flat top of the aerial would attract

thunderbolts. When I finally connected the aerial to the receiver I

heard ABSOLUTELY NOTHING."

I asked him how he tuned the receiver. He said he had put many

taps on the coil and he twisted his antenna to these taps trying

various combinations with the tuning capacitor.

"All I heard was this breathing noise. I learned later that it

was the 'carrier wave' of a broadcasting station without modulation,

but I didn't know what that meant. As my friends also heard the same

noise I was convinced my receiver was working. We soon found out that

the long wave transmitter at Ankara, the capital of Turkey was making

test transmissions without modulation. Ankara was one of the first

broadcasting stations in that part of the world."
