Hi Piet Blaas

The Elektromekano radios were bought in a junkyard. They used to buy old ships for dismantling and take away some electric engine parts. They had all kind of radios there and several radio parts. They also had a fabulous radar that i wanted to get my hands on but it was definitely too heavy and too big for my car. believe it or not, the radar had the incredible price of 50 Euro (monitor screen and tx/rx system, no antenna). It was from the late 1940's. just a sad note: all the radios and electronic equipment on the junkyard was hammered after a few weeks there. If they didn't sell it to a crazy guy like me, all that goes down to pieces, by hammer.

These two Elektromekano radios, i believe, are also from the late 40's, early 50's. They are both in working conditions.

The Elektromekano P78 is a receiver that covers from 230 to 540 Khz and works with power (AC) ranging from the 100 to the 160 volts. I ran it on 110 volts for quite some time, while testing.
The antenna connector is not standard. I believe it was connected inside the rack directly to the ship's antenna cable.


The Elektromekano SM108 KM2 is a crystal operated TX/RX in two frequncies: 500 KHz and 8 MHz. It's power is generated by turning a metal handle that the operator has to stick in the top right corner of the radio panel.
This radio was meant to be used in lifesaving boats. That is the reason for the mechanical power generator. It has a lamp that indicates when there is power enough to operate on the included batteries, wich i believe is an electrolytic condenser and not really a battery.
Right below (in th photo you can see it) the place to insert the handle there is a reel of electric wire that should be thrown into the water to serve as a "ground connection.
The valves (tubes) are:
EK 90
ECC91
EF93 (2)
EL90
They are all british made Mullards.

It is magnificently built. And, i was very lucky because this radio, being meant to be used in a lifeboat, came closed in a waterproof/weatherproof metal case. Therefore, it is practically rust free. I believe mine is quite rare as all the panel plates are written in portuguese.

Not the same on the P78 wich has the panel in english.

Hope this is the type of info you were looking for. If not, if you need any further details, let me know.

Greetings

Paulo
