standards under contract to NOAA/NGS for the VLBI stations that we equipped with
Mark III VLBI terminals for project POLARIS - <st1:City w:st="on">Fortaleza</st1:City>,
<st1:City w:st="on"><st1:place w:st="on">Hobart</st1:place></st1:City>,
Hartebeesthock. I don’t know if they are still in use. I know that I
found Harry easy to work with and he was dedicated to delivering the best
produce that he could, at the lowest cost. At the time, Harry and Bob Vessot
disagreed about the best design for the MASER oscillator cavity – Bob built
his out of Cer-Vit to minimize temperature effects and make the most stable oscillator
that he could. Harry made his of Aluminum, and had a feed back loop to
compensate for dimensional changes. We bought a Vessot MASER for Westford, and
it performed well, but it was considerably more costly than we could purchase
from Harry Peters, so we purchased three from him, and they also performed
well. I’m sorry to hear the he has passed away – seems like every
day I hear about the death of another old colleague. Thanks, Tom Clark, for
passing on the information and for the nice summary of Harry Peters life and
contributions to science.<o:p></o:p></span></font></p>
