| Ship 33 | ||
Sending the Radio Codeword on 14.9.1940. |
||
============================== |
||
| On 9/14 a radio codeword and a radio message was sent from ship 33 to the homeland. Since the transmission of a long radio message could very likely be detected by the enemy direction finding bases, it had to be ensured that this only happened at a time when the connection with home was ensured. The radio codeword was used for this. Norddeich acknowledged the radio message sent by the ship, which thus confirmed communications. In addition, the codeword conveyed basic reports in the event that the radio message from Norddeich could not be recorded correctly. | ||
| 18 meters was chosen as frequency because this wavelength was heard the loudest in the last few days before it was sent. This wavelength was also used because it is less noticeable than 24 and 36 meters, depending on its propagation, by the enemy B-Dienst and bearing observation service, and Norddeich probably has the least interference on this frequency. At 18:17 hours GMT, reception was made on 18 meters at Volume 5 and the radio password was sent in the 5 minute break. Since Norddeich did not acknowledge in the following periods, the radio password was set at 22.16 GMT on frequency 36 meters, which came through at Volume 5 in between, while 18 and 24 meters could only be heard faintly. Norddeich acknowledged at 22.30 hours. GMT. Since the connection was now secure, the radio message with 38 groups 5 digits after radio instruction for HSK was sent at 22.37 hours GMT. There was no acknowledgment from Norddeich. A radio message from SKL transmitted the following day that the Radio message had been only half received and unclearly. It is assumed here that interference impaired reception by Norddeich. | ||
