Dutch D-class Shell-tanker radio station
Camera: Asahi Pentax Spotmatic II
Typical radio station as fitted by Radio Holland in the ’60 ‘s
on Dutch D-class Shell-tankers.
from left to right
1 Marconi "Crusader" SSB transmitter, (the one with the 100 ledex switches)
2 Marconi antenna switching unit
3 Skanti portable life boat transceiver (beneath "sloepszender" sign)
4 Renovas reserve/emergency transmitter (MF-band A1/A2) ,
5 Redifon R408 main receiver,
6 Marconi "Argonaut" VHF transceiver (FM) control unit,
7 Sailor 46TNAW reserve/emergency receiver,
8 Radio Holland switchpanel with:
morse auto-keyer, reservebattery controls, meters, speaker, DF request signal etc.
9 receiver antennas connecting box, and
10 receiver antenna protection unit.
All very basic, simple, nothing special, no luxury.
Not a very pleasant radio station to work in.
Very little daylight entering through the 2 portholes, each at a far end of the room.
Very odd !
As a bonus the ships main engine produced ionized exhaustgasses.
Resulting in poor or very bad reception or no reception at all.
These gasses could charge the transmitting and receiving antennas to very high voltages.
With very loud frightening big flashes in antenna switching unit as a result.
Also maintransmitter end-stages were destroyed in some Dutch D-class ships.
All antennas must be "earthed" when sailing before the wind !
And it took some courage to do just that.
Later this problem was solved (more or less) by installing earthing coils in the main engine exhaust system.
