<div>I located some of my info on the PLAT program. It stood for
Pilot Landing Aid Television. It originally was built around VR-1100's,
but I'm fairly certain I have some later info indicating a change to VR-660's at
some point.</div>

3 other AVR-1’s so it was not worth trying to have a mix of heads.</span></p>

<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">I am
impressed how so many of you guys remember not only the model numbers of the
helical machines but some of the history of them. I always had trouble with
model numbers, Revision Numbers, etc.</span></p></div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">CBS
only went so far as the BVH-2000's after the BVH-1100A's as far as I can
remember, although there is one PAL VPR? not sure of the number, which
fortunately has been working OK at least till I retired. There are a
couple of BVH-3100's (?) around. I don't know where they came from,
perhaps a garage sale. They have the self threading feature. I don't
know anyone who had trouble with threading up tape and it seems like a lot of
work to come up with one of those. I didn't like working on them because
of the keypad on them. Almost everything I needed to do was by inputting
codes from that damn keypad, even putting it into E-E. Fortunately there
was one maint. tech who would bail me out as she remembered the codes.
When she wasn't around it was a pain as the book was never in the same place
twice.</span></p></div>

<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">I ran
into one neat machine. It is an Ampex 1200-E with the flat
deck. It belonged to Charlie (Chubby) Salvato from Orange County,
NY. It was put together by AF Assoc. They installed Volvo motor
mounts on it with wheels so it could be rolled anywhere with just your
fingertips. It also had no Amtec, Colortec, Proc, etc. They put in
a CVS Digital TBC, I don't remember the number, but it had a "16" in it (I
think). CVS had a mod for it to work with Quads, it was a board which
had to be installed in it. I remember taking it to CVS to have it done
for Chubby.</span></p></div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';"></span> </p></div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">This
was done around the time the AVR-2 came out. Ampex propaganda had fotos
of 2 people picking up the top deck then the TBC bay and showing how easy it
was to move. Chubby bragged how easy this machine is to move. A
cavewoman could do it alone. He brought it to my home from time to time so I
could tweak the servo, etc. We just rolled it in and out of his van
easily. That was the only time I had a Quad in my
garage.</span></p></div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';"></span> </p></div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">It
was so neat, it could be moved over bumps easily and when it stopped it would
just sit there and rock back and forth a couple of times. Then all you
had to is plug it in the wall, put video in and record or take video from it,
no need for sync gen. etc. (It still needed air). I asked him about it some
time ago, he said he sold it to a TV station in P.R.</span></p></div>

<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">By
the way Chubby was known for his "Fire Engine". He had a big fire engine
with a 70 ft. or so ladder on it on which he had a camera mount which he
rented out for sport events. Perhaps some of you have seen it.
Last I heard, his son was running it around for him.</span></p></div>

<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">There
was a BVT-2000 connected to the the Ampex VR-2000's, before they were
removed. It was used for SCH purposes as it was feeding Betas and
D-2's. I tried feeding the BVT-2000 right out of the Demod, but it
couldn't seem to handle the head switching. I tried widening and
increasing the switching suppression pulse but to no avail.</span></p></div>

<div>
<p class="MsoNormal"><span style="font-size: 10pt; color: black; font-family: 'Arial','sans-serif';">Another
interesting thing, sometime in the 80's, my Navy Reserve unit was having a
triple Retirement and Change of Command. I was given the job of getting
it done. I was able to get the "Intrepid" in NYC for the
ceremony. While schmoozing the museum curator we came across
a room full of 2" video tapes. He told me they were recordings of
flight ops. while she was in commission. (One of the early uses of
video tape was recording flight ops on carriers so the pilots could watch
their landings, and they still do.) Also that he wanted to get them dubbed to
U-Matic as he wanted to use them in displays around the ship. (The
machines they were recorded on were gone.) I forgot all about the first
thing I learned in the Navy, "Never "Volunteer" and I offered to help him
out. I also forgot how heavy a 2" reel of tape can be after carrying
them about a mile, from the Intrepid to CBS, and back but I needed the
exercise. I thought I was in deep trouble with the first reel. I found
they were recorded at 7.5 IPS. Would you believe we also found some
5 Mil heads on the ship which were in good shape. I put one on the Quad
near my shop and had good luck with it. The only problem is they
were ball bearing heads and made about 10 DB more noise than the air bearing
heads do and I was trying to do this whole job un-noticed. Fortunately the
maint. manager at time was interested in WWII planes as his father worked for
Grumman designing some of them and let me get away with it for the small price
of VHS copies of some of the tapes. The tapes were fabulous. I managed
to do about 50 reels for him. I don't know what model VTR they were made
on.</span></p></div>
