Notes

NAGRA T-RVR - A monaural or stereo machine designed with the 19" rack format. It is a reel to reel 1/4" tape recorder designated for automatic long recording using the four  standard tape speeds. The machine is equipped with an automatic start recording device actuated by the input signal and, at the tape end, allows automatic connection to another machine that starts to record in a new tape without loss of signal. When equipped with the accessory RCHS, Time Code Reader Searcher, the machine allows the high speed search of a particular sequence when its time code had been entered by the keyboard or from its memory. This machine were used by intelligence services of several countries and logging service of radio stations.
