Something about *accuracy*, rather than just rants, bothers you?

either? <snip>
Floyd said:So you are claiming they needed to cool a DMS to 62F to get it to
operate? Do you have any other fairy tales? Why do you make up
such goofy stories?
What you are saying has *nothing* to do with the DMS design. It
says that the HVAC was improperly designed.

when someone posts to 3 am, then gets up at 8 am just to resume a flame
war, as it Bob's case, on a daily basis, I'd say that's a flag of a
personal addiction problem <snip>
TROLL ALERT!
Of course, Nudo doesn't understand the idea of "time zones," nor does
he understand that "goo goo groopz" doesn't give reliable message
posting data.
Not understanding gg's shortcomings doesn't make him a troll. <snip>
DeserTBoB said:Total nightmare. Hams that like old Collins gear wouldn't be Collins
fans much longer if they only saw what Collins built for commercial
microwave. It was a total disaster.
The Collins C-band equipment they sold to CATV and TV stations was
pure crap as well. Fixed tuned with a single channel filter at the
antenna, and a mechanically tuned 4 GHz oscillator. A poor noise
figure, and they ran so hot that the green fiberglass PC boards turned
dark brown in a couple years of use. <snip>

after the built elevated 85 ... essentially thru part of the plant site
... people would comment that their radar detector would trip passing
the path between the roof of bldg.12 and relay tower.
there was completely set of c-band stuff for satellite that was but in
by SBS on most plant sites (sbs had been formed by comsat, ibm, and
aetna). couple posts about the T3 encrypter on the TDMA channel ... the

(... and some clear-channel T1 on telco (although we had to convert
when the local telco's came back and said that they would no longer
support clear-channel T1s ... and we had to play games with 193rd bit

was TDMA earth stations that had KU-band transponder on SBS4 (or SBS-D)

There is an abandoned C-band earthstation near here I'm trying to
track down. It was the only uplink built by Microdyne, and is supposed
to be the infamous site used by "Captain Midnight". <snip>
I worked for
Microdyne for a number of years and collect their odd limited run
products, but this one would fill my garage according to one of the
engineers who worked on the system design. For instance, I may have the
only surviving C-band signal generator they built for the production
line testing of CATV & broadcast downlink equipment at the Ocala plant. <snip>
DeserTBoB said:That wasn't the GTE DOMSAT station in Homosassa, FL, I'm sure. I
think that one was scrapped. It had two 105' Sylvania/Rohr bean
waveguide antennæ and Lenkurt GCE. It was a sister station to Sunset
Beach, HI (one antenna) and the main GTE station at Triunfo Pass, CA,
where I worked for years after AT&T bought it in 1986.
Didn't Microdyne become part of Satellite Transmission Systems later
on? They're in Melboune.
