Nordell & Koskinen’s crystal receiver, 1928

The crystal receiver, manufactured in 1928, was the Salo-based Nordell & Koskinen’s first own product. It was only manufactured for a short period of time in the summer and autumn of 1928. According to one of the owners, Fjalar Nordell, crystal receivers were already old news at the end of the 1920’s. They assembled crystal receivers and sold cars as well.

On the front mask of the crystal receiver there was a glass tube -covered crystal that needed to be tuned to be able to listen to transmissions. Headphones were needed to listen to the crystal receiver.
