- Notes
-
In 1927, the production of detector crystal radios was commissioned by the newly established Zagreb radio station. Due to the desire to increase the number of subscribers, the management of the radio station has commissioned thousands of radio detector receivers from Paspa. Each new Radio Zagreb subscriber was given a free kit - a receiver with a crystal detector and headset.
