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.
