Last Saturday there was an exhibition at the Tele and Radio Technology Institute in Warsaw. We showed what we do today, but also what we did in the past. In the early 1950s, we had an experimental TV studio.

The former Studio is now a conference room.
We showed some old radios and TV sets.
To our surprise, the children were very happy to see themselves on the screen of the old KVN receiver and the CCTV monitor of the Polish Alfa II system.
