the web page of            Ralph M Klimek

Greetings to the other  Ralph Klimeks  that seem to exist elsewhere.

 known as VK3ZZC in ancient times, and now coming to the aether near you !

The most cool ™ web page in the entire universe

a contemptible miscellany of offcuts, broken ideas and random musings

for further information please email  


if you find the content of these pages usefull, let me know. There is more stuff to come.

at least the fully sealed die cast enclosure was Larkspur grade!

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.
