[QuadList] ATSC 30 station taking shape for NAB/Image Orthicon cameras r...

Thu Apr 20 08:56:29 CDT 2017

I also worked at the U of M and it was interesting to see pictures from  
these cameras. A lot of light was needed.  1000 foot candles at f  8.   They 
were TK-45 not 44.  I got a copy of the instruction  book from Chuck Pharis 
last year.  It turned out that it was the book from  the U of M.

The Museum of the broadcast  television cameras  has a good list of RCA  
Cameras at http://tvcameramuseum.org/rca/rca_list.htm   by my experience they 
are a missing one camera type, that is the original  TK 44  a three Vidicoin 
color camera designed for use in operating  rooms, 10 were produced for 
medical use. to my knowledge only 3 were sold  the rest were given away. I know 
it well as I worked with it at the Army  Medical Center in 1956-7 and at 
the University of Michigan in  1958-62. Later while at RCA I sold the TK-44A  
(Plumbicons)  after an abortive attempt by RCA Lancaster to provide a 
modified 3  " IO to compete with the Philips Plumbicon Camera.

Paul, Where will you be located.  I spent 22 years with RCA  (61-83) and 
never came across a TK34.

DARN!  sorry to miss this...

I did   see Paul Beck and crew last year though and enjoyed seeing the old  
 gear and actually meeting Paul in person at last.

Is   Paul's  crew also  going  this  year to  demo  stuff?

Thought  you'd want to know that the ATSC 3.0 demonstration station is 
taking  shape on Black Mountain in Las Vegas.

One of the people helping  to build the station is QuadList member John 
Turner, head honcho at  Turner Engineering in New Jersey.

He advised the Old VTR's group  this morning:

"We are building a real time ATSC 3.0 transmission  system on ch 50 at 
Black Mountain for the convention. Pulling this RF  off air at the Grand Lobby 
and North Hall. Big demo will be a 65” LG  OLED consumer receiver being sold 
in Korea today.

Content is UHD  stored on a Harmonic (Omneon) 50TB, 2 RU server. The server 
is playing  out digital video at 8X 1080I!
Sure interesting to compare this new  system to the 1960’s analog VTRs.

John (My 50th consecutive NAB  this year)"

Turner helped build the ATSC 3.0 station at NAB  last year, and has 
participated in a number of other NAB demonstration  projects over the last several 
decades.

He also enjoys restoring  Quad and other vintage video tape equipment in 
his company's New Jersey  facility.

The "NextGen TV" demo area is in the Grand Lobby   between North and 
Central halls.

More about the ATSC 3.0 demo  here:
http://atsc.org/news-release/next-gen-tv-hub-showcase-benefits-new-broadcast
-tv-standard-2017-nab-show/#.WO-pPjxHaEc

"Tomorrow's  technology" is just a short walk away from where the Museum of 
Broadcast  Technology is bringing a showcase of vintage television gear to 
the  entrance of Northhall opposite the taxi drop off.

In the last  several years, the Museum's exhibit has showcased 2" quad 
video  recorders along with a number of portable television cameras from the  
mid to late 70s and early 80s.

MBT's Paul Beck advises this  year's display is RCA:  "One original TK-31 
with tubed power supply  and one TK-34 with WP-16 and external focus 
regulator. And... an  original ZOOMAR 3x1 studio lens.

Yep !  (Image) Orthicons  are making a come back !!! You just wait and see  
!!!!"

Should be an interesting NAB, that's for  sure!

I'll have an announcement about the "Annual Quad Videotape  Group Luncheon 
at NAB" in a forthcoming separate email.

As always  it will be on 12:30 PM, Tuesday, April 25, 2017. The location is 
being  identified. It will likely be near the MBT exhibit.

Looking  forward to seeing folks there. Unless something changes 
dramatically in  the next two weeks, we will be walking the floor rather than standing 
in  a booth.
