Operating instructions - this page is a stub

This page holds some guidelines for operating the 32620 speech/morse generator, that was used during the Cold War behind the Iron Curtain for the Numbers Stations of the Eastern Bloc and its allies. For a more complete (but partially incorrect) description of the operation, please refer to the original German manual of 1985 [A]. The device was initially developed for the East-German Stasi, but has an English user interface to accomodate non-German users like Cuba and Poland.

Manual programming
Clear memory and select default settings
Before entering a new message, it is recommended to clear the memory contents. This is also necessary when the memory contents have been corrupted, which will be the case when the device has been switched off for an extended period of time. In this situation it is also recom­men­ded to select the default mode of operation.

The procedure below describes how a message can be entered manually, and how the numbers can be delivered as a spoken message. In this mode, the message format is free, as long as the first character is a number. Messages may contain the numbers 0-9, but also the space character (SPC), Achtung (:) and Trennung (/). The message must be terminated with a (+) character.
