  Marinetta 3

Is a naval distress radio, working on three distress frequencies . No infos could be found so far, even Marine Radio specialists could not help.

It was built by Skanti, like the more common successors.

Obviously, the model was the SCR-578/BC-778 (also called "Gibson Girl"). The housing, the hand crank, the CW- mechanism and even the connecting plug are absolutely equal. (see the picture gallery).

However, unlike the SCR-578/BC-778 (a transmitter), the Marinetta 3 is a transceiver.

  • Three fixed frequencies can be used in AM- mode.
  • By usinng a mechanical CW- Mechanism, emergency calls can be transmitted;
  • CW- calls can be sent by using the CW- key on the front of the radio.

    The receiver is transistorised, the transmitter uses three tubes:
    2 x ECC82 and 1 x 12A6.

    Frequencies:
    500 khz
    2182 kHz
    8364 kHz
