[Moon-net] 10 gHz tellurometers/with Voice Capabilites.

[Pat Barthelow]

Folks:

I have a pair of tellurometers,  70s vintage Electronic Microwave distance 
measurement equipment.  Military Versions with a built in the box antenna, 
about 1 ft dia.  Klyston tubes, 10 ghz.  Really nicely packaged.

Built in full duplex voice comms for the surveyor operators who used them 
for distance measurement.
Can be easily tripod mounted, and use 12,24, or 110- vac for power. Has 
anyone used these for terrestrial microwave comms, or maybe even adapted for 
EME

Only about 30 mw out, but…with 65 db gain of Jamesburg, maybe possible for 
EME?

Anyone know of a source for Surplus equipment manuals that might have one 
for these MC-8s?


See for pictures of similar, but not exactly the same units Mine are 
streamliined, with a square box, and built in parabloic antenna.:

"TELLUROMETER"Discussion:
The first successful microwave EDM was invented by Col. Harry A. Baumann of 
the South African Trigonometrical Survey, developed by Trevor Lloyd Wadley 
of the Telecommunications Research Laboratory of the South African Council 
for Scientific and Industrial Research (CSIR), and manufactured by 
Tellurometer Pty. Ltd. in Cape Town. The Tellurometer was designed to yield 
geodetic accuracy over geodetic distances, but it was also useful for second 
order work, especially in areas where the terrain was rough and/or the 
temperatures extreme.
The original Tellurometer, known as the Micro-Distancer M/RA 1, used a 
continuous wave at 3,000 megahertz, modulated by 10 megahertz and three 
other nearby frequencies. The remote station reradiated the incoming wave in 
a similar wave of more complex modulation, and the resulting phase shift was 
a measure of the distance traveled. The results appeared on a cathode ray 
tube with circular sweep. This instrument could penetrate haze and mist in 
daylight or darkness, and had a normal range of 30-50 km. It was covered by 
patents in at least eleven countries granted to Wadley and assigned to the 
CSIR; the U.S. patent (#2,907,999) was entitled "Determining Relative 
Position by Means of Transit Time of Waves.
