<DIV>NTSC was done in 625 with a higher sub carrier. It was used in closed
circuit for a while in Europe. RCA use to make the modules for the solid
state color encoder with the 4.42 circuits in them. They were on the TK-27
that I had. </DIV>

the heterodyne process here in Aus as far as I know, but I was looking through
the tender documents for our first VR1100 and at one point it was stated that
the machine must be capable of being "modified to record and play back an NTSC
signal recorded at 625 lines". Of course this was when PAL was still in the
Lab. Does anyone know if any work was done running NTSC on 625? By the
time we bought the VR2000's (used in the Mexico Olympics and then shipped back
to Sydney!) high band and Colortec were in existence.</FONT></SPAN></DIV>

<DIV></DIV>The RCA modulator was direct color recording but of a non-standard
nature. Heterodyne was the process of color recovery/conversion (the scheme to
get a reduced bandwidth, somewhat unstable but watchable color picture off
tape and over the air with FCC waiver) until the direct recovery method was
developed some years later (Ampex Colortec).
<DIV><BR></DIV>
<DIV>At "The Reel Thing" St. Louis, 2009, I made a presentation on the
recovery of the Cyd Charisse special, an RCA modulator color program. Part of
that presentation was a display of a typical NBC Burbank work order indicating
the mode of the recording. A portion of that work order is displayed
here:</DIV>

<DIV><BR></DIV>
<DIV>In 1958 at the beginning of "Color City" color recordings, the operator
had a choice of using the Ampex modulator on the Ampex machines for mono or
the RCA modulator for color although I have encountered mono recordings using
the RCA modulator scheme on Hope black & white programs from 1959. VTR 1
& 3 were VR 1000's. They were transports with no overhead bridge. In the
rack were both modulators.<BR>
