| An all valve Loran B reciever. I can tell not much more about it, this picture taken at the shack of VK3ASE | ||
 |
 |
 |
| Loran B was a radio navigation system that was discontinued I think about 1980. This valve "computer" generated pips on an air radar set that "indicated" where you were. The circuit would appear to be a set of programmable delay lines which you turned until "something happened" or something was indicated on the radar display. You then read the dials and by referencing a chart you would know where you were. Thats all I know about it and thats probably just a guess. Those of you that listened to the Hams late at night on 160 meters during the late seventies would hear the rapid pulse like noise emanating from across the planet. These were loran B, a planet wide ship and aircraft hyperbolic navigation system. This apparutus is what decoded and displayed this data. | ||
