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>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>
