The Radio Traffic during the Capture of the British Steamer |
|
|
"PORT BRISBANE". |
|
================================================================== |
|
|

The steamer recognized by day at the smoke plume was closed at night and at 22.03 hours received the stop shot and the visual order not to use the radio. Since the steamer still starts to give an emergency message, it was shot at and after the third salvo the radio station was put out of operation by a direct hit. During this time, the steamer managed to transmit its emergency message with position and name once. With the first "R," the jamming began. The jamming was "ve ve ve" with an illegible name, followed by a hissing noise; the entire traffic lasted about a minute. After the RR report, the 600-meter wave immediately became quiet, and after about 10 minutes, normal steamer traffic resumed, likely transmitted by the British steamer "CHANCELLOR" on shortwave. At 00:24 hours the British steamer "AGAPENOR" repeated the R report and was heard very loudly. |

The auxiliary vessel of Ship 33 also observed this jamming traffic and determined that the Marconi transmitter was not suitable as a jammer, as it was drowned out by the other transmitter. Likewise, the DEBEG transmitter s 356 s was insufficient. |
