Questions from Jerry Proc VE3FAB

While searching for information, I stumbled upon your 291 BLOG and
wonder if you can provide any assistance in answering some questions.
Since 2004, I have been documenting SUPRAD stations past and present.
http://www.jproc.ca/rrp What started out as an innocent equipment
identification exercise has turned into a major research project though
no fault of my own :-)

At the end of June I attended the Old Timers Reunion in Ottawa. On the
way there I stopped at the C&E Museum for a photo shoot. As a result, I
have created two new sections at the top of the CFS Alert document :
http://www.jproc.ca/rrp/alert_photos2.html

These are titled "Dual and Single Intercept Positions". Of course, a
number of questions have arisen. Do you know of any 1980
or 1990 vintage operators who might be able to answer any of my
questions below.

DUAL INTERCEPT POSITION

1) Is the dual intercept position display fairly accurate and could this

configuration be found at other SUPRAD stations such as
Alert, Masset and Gander?

2) Why no table in front of the rack? Did the operators stand for the
entire shift to use this equipment?
However, if a table were placed in front of the rack , the operator
would always have to be getting up to work the equipment in the upper
reaches. Was the equipment mounted exactly as shown ? Was there a table?

3) I find it very difficult to listen to two people simultaneously and
understand both. Would the same problem apply when trying to tune and
analyze two sets of signals from two receivers in this dual intercept
position? Was this something you just learned to do?

4) The top most unit in the dual intercept cabinet is the Pylon 095 RF
Distributor. What was its purpose? Did it act as antenna multicoupler
for two receivers?

5) Next down is the Pylon 364 which I am calling an "audio panel" for
lack of a better term. What is the correct term? What was its purpose
along with the jack field below it? There is no hook to hang the red
handset on. Is the 364 panel really supposed to be here or is it a case

of the museum lacking a hook for the handset? The red handset is just
hanging to the floor, a small detraction to the exhibit.

6) Further down is the Pylon 125 tuning indicator. What was it's
purpose? Did a real setup use two of these since only one is shown?
Please explain.

SINGLE INTERCEPT POSITION

8) For the single intercept position, some similar questions apply.
Why no table? Is it simply missing from the display?
Did an operator have to stand the entire shift?

9) Did the single intercept position have a Pylon 125 tuning indicator
and 364 audio panel. If not, why?
Would the single intercept position be views as a "half work load "
position when compared to a dual position.

Any assistance you can provide will be most appreciated since I am
trying to preserve the history of the 291 trade.
I have never served in the military so I apologize if the questions
sound too elementary.
