    This 1920s TRF radio manufactured by Signal is constructed on a breadboard Tuning a TRF receiver, like this 5 tube Neutrodyne set from 1924 with two stages of RF amplification, was a complicated process. The three tuned circuits, controlled by the 3 large knobs, had to be tuned in unison to the new station.

    It generates a stream of real-time decryption keys which are broadcast over the Internet to remotely located satellite receivers. Limiting factors in the number of remotely located satellite receivers are the network latency and the period between the updated keys and the ability of the card client's receiver to use the decrypted key stream.
