[Boatanchors] Anybody remember the "Wobulator"?

Wobulators were used for a lot of things in my time.

One of the more interesting ones I remember is:
I worked as an engineer at KTUL TV Ch. 8 Tulsa from 1958 to 1966 and our 
News Dept got a KINESCOPE Film transfer unit.

A 16mm film camera was mounted to film a kinescope tube.  Since the tube 
scanned 525 lines(not all active) and we played it back on the same type 
scanning system, the lines would not match up and lots of detail was lost.

SO... ENTER the professional kinescope  film transfer unit, costing many 
thousands of dollars.  It was bought since its quality was so good.  
It's main secret was the wobulator, which wobbled the scan lines, 
allowing for better resolution and quality of picture in the film 
transfer process.  It worked pretty good too.  Considering.

Before that the mounted the camera in front of a TV monitor had a 
resultant film picture that looked pretty soft and grainy.  So the 
wobulator really helped.

Seems like we could adjust the "wobulation effect" for best detail too. 
They also used a high intensity CRT with a coating that caused the 
picture to be retained a bit longer but without "trails", as I recall.  
Hard to remember and bring it all back.  Anyone remember "travel ghosts"?

Then the video tape recorder wiped the film/kinescope transfer process out.

That was a long time ago... things have really improved a lot since 
then...   WOW...

turn into the wind to take off.
It's the push against that what resists you
that can help you succeed.

July 2011, Bill, W5SJ, and I
had a blast in the Caymans.
He was ZF2EZ and I was ZF2UQ.

Recently I was HP0/W5UQ/MM2 on
Carnival Cruise Ship in Gulf/Caribbean.
There were several USA Hams on this trip.
