| Comments |
| This model is a descendent from the single conversion superheterodyne UE 11(1953). The UE 12 was designed for the marine market and licensed as a class one receiver by the Deutsche Bundespost. A standard receiver like the competitor Siemens E 310 (= E 566) on German and Scandinavian ships. The eleven bands are selected by push-buttons. The tube currency is 0.1 A. |
| Variants |
| The common version includes a transformer in the cabinet. The UE 15 is similar but didn’t have the first LF-range. |
