Not even a radio-amateur (yet), this picture was made on 22 November 1979 (I was 23 here):
my FIRST day of my FIRST job on my FIRST ship: merchant marine Radio Officer....
This is the radio-station of m/v Raamgracht / PFON, a 82 mtr coaster.
The 19-inch racks contain: 2x Skanti R-5000 receivers, in the middle rack (top) the battery-charger for the batteries of 500 Khz emergency transmitter, the latter is on the far right side, with under it the Automatic Alarm Device, that starts ringing when an emergency signal is received.
Above the transmitter you see a SOLID copperwire to the antenna on top of the wheelhouse.
My first voyage: From Amsterdam to Hudeidah (in Yemen) via the Suez Channel.
