Speaker used with Marconi CR100/2 Communications Receiver

Speaker used with a Marconi CR100/2 Communications Receiver. Part of the equipment Geoff Perry and Derek Slater used to track Soviet space activity at the Kettering Grammar School Group.

Slater and Perry worked at the Kettering Grammar School together and shared an interest in space. They used borrowed and inexpensive equipment to teach their students how to track satellites. In the process of doing this, the Kettering Satellite Tracking Group was born - which in turn led to the discovery and announcement of a secret Soviet launch site at Plesetsk, securing the Group worldwide media attention.

The Marconi CR100/2 Communications Receiver covered HF (High Frequency) up to 30 MHz and was used for tracking Soviet satellites and spacecraft operating in the 15-20 MHz part of the spectrum. The speaker connected to the unit so that the signals could be heard and recorded.
