That would be an "Avionic Dittel" Radio.........Not to be confused with
"Walter Dittel"
These radios are however similar to the ATR720 sold in the past by Filser,
the pin outs are the same although some interal components are different,
the manual with digrams for wiring are available from Filser website
http://www.filser-electronic.de/inde...als&language=e

ATR720C Manual is in English, ATR720A (like what I think you have) is only
German, but both radios also have same wire pin-outs.
